Opus remained better than GPT for me, even after the release of GPT-4o. VERY happy to see an even further improvement beyond that, Claude is a terrific product and given the news that GPT-5 only began its training several weeks ago I don't see any situation where Anthropic is dethroned in the near term. There are only two parts of Anthropic's offering I'm not a fan of:

- Lack of conversation sharing: I had a conversation with Claude where I asked it to reverse engineer some assembly code and it did it perfectly on the first try. I was stunned, GPT had failed for days. I wanted to share the conversation with others but there's no way provided like GPT, and no way to even print the conversation because it cuts off on the browser (tested on Firefox).

- No Android app. They're working on this but for now, there's only an iOS app. No expected ETA shared, I've been on the waitlist.

I feel like both of these are relatively basic feature requests for a company of Anthropic's size, yet it has been months with no solution in sight. I love the models, please give me a better way of accessing them.

Both GPT-4 and 4o have been completely useless for coding in the past couple of weeks for me - constant errors, and not just your typical LLM inaccuracies but incapable of producing a few lines of self-consistent code e.g. defines variables foo on one line and refers to it as bar on the next, or it misspells it as foox.

Waht language? Because I'm guessing they work well for languages with a large amount of training data like Python (in my experience), less well for less used languages like Zig or Clojure (haven't tried them but that's my theory)

From my experience, GPT-4 works well with both Clojure and Zig. A lot of it depends on the way you prompt though. For example, asking to start with a C or C++ example and converting to Zig often works better than starting straight with Zig. The same strategy works with Java and Clojure too.

I use it for Rust and it's.... meh. It gets things wrong enough that I don't reach for it except to help me reference certain docs. It tends to hallucinate APIs and semantics that just don't exist. Honestly couldn't imagine using it with a dynamic language.

Python here. And like they said, only noticable in the last few weeks.

I've been seeing this too. Always hard to tell what's a real change vs the rolls of the dice lately but I've been having weird python inconsistencies too, in very short snippets doing pretty simple things.

For me it has been very repetitious despite my instruction to the contrary.

I've been experiencing bizarre typos and misspellings that I've come to describe as the model being drunk. Things like it writing peremeter instead of parameter

Yeah, misspellings were something so rare that I thought an LLM was incapable of producing them.

Yet over the past few weeks GPT-4 and 4o make them all the time. It will randomly change my postgres schema from public to publish. And, well, just this one for yourself:

> *Using the 'kubectl cp Command*: Execute the 'czygk cp' command to copy the file from your local machine to the pod.

Today, I asked 4o how to get around conditionally executing React hooks (illegal in React) and it rewrote my code to simply do it again but it merely swapped the order of a ternary, performance possibly worse than gpt3.

Maybe they’re weakening it because they expanded their free tier, but it has become surprisingly bad.

The level of misspelling is insane at the moment. It does it almost 50%+ of the times. I just started using claude 3.5 and the difference is night and day.

It's the same model though. Maybe your perception has changed.

I have first noticed logprob fluctuations in GPT-4o. Perhaps the same phenomenon is also going on with Turbo. I din‘t recall specifics but it was naming inconsistencies with variable names, meaning: same variable name got a typo somewhere, but the typo was close enough - perhaps a space vs. an underscore or something like that.

Model could be the same, but maybe some in the infra is different.

I can’t speak for what OpenAI is doing, but I’ve noticed those types of hallucinations occurring when I quantize a model beyond a certain point.

Maybe they are trying to cut down on memory usage ?

Is it the same? On the Models page of the API docs it says that GPT-4 is using the June 13th which would be different than the March 23rd.

> I had a conversation with Claude where I asked it to reverse engineer some assembly code and it did it perfectly on the first try. I was stunned

I share the same experience with you but with Claude 3 Sonnet. I can’t count how many times I’ve shared some code with Claude with barely any hope because other GPTs failed aswell, yet, Claude surprised me and performed the task with success.

I’ve actually reached to the point that I expressed my gratitude to Claude because of how well it performs on coding tasks and other tasks in general. I don’t know what Anthropic did, but something did they right.

Being able to handle large amounts of tokens, “understand” and perform tasks on it & spit out large amounts of data back with barely any cut-offs (unlike Gemini) has made me feel like Claude is at the moment the best option.

I do wonder if GPT quality fluctuates seasonally, or with electricity costs, in an engineering effort to balance costs with performance.

I agree on all your points, but would like to emphasize that I really do enjoy the voice input voice output thing that chatgpt's app has. Its not how I use it when working, but when commuting, a lot of times, I'll turn on the the chatgpt app and have a conversation with it exploring ideas related to work or side projects. Its better than NPR, and I can't listen to the '3d6 Down the Line' podcast everyday, just once a week.

I've been subscribed to PHind, which is a decent service allowing access to their models, chatgpt 4 turbo and o, and claudes. Its been incredibly useful, especially with their search integration. Unfortunately, while chatgpt can be used 500 times a day, Claude is only 10, although I guess it goes into an API like payment mode after that on top of subscription.

I sure wish I'd buckle down and calculate my usage to really get an idea of whether subscription is cheaper or more expensive for me compared to API.

Short of switching between models (which at least OpenAI definitely does for free customers, but I believe they always indicate it), how would that work? Different quantizations?

caught me speculating. I suppose some mild quanting and/or prompt injection to keep responses smaller unless specifically asked: e.g. use ...

> Lack of conversation sharing... [there is] no way to even print the conversation because it cuts off on the browser (tested on Firefox).

Until they make conversations shareable, in the meantime you can print the whole page in Chrome by:

- going to Developer Tools (Ctrl + Shift + I)

- opening the Command Palette (Ctrl + Shift + P)

- searching for 'screenshot'

- selecting Capture full size screenshot

I recently released Slackrock [https://github.com/coreylane/slackrock] that you may find helpful, it's a Slack chat app that can access several FMs (including Claude 3.5) via AWS Bedrock. Responses can be easily shared with others by inviting them to your channels, and Slack has an Android app. It doesn't support attachments (yet) but I'm working on it!

cool!

> Lack of conversation sharing

You can use my product https://ChatHub.gg which supports dozens of chatbots including Claude and can share conversations from any of them.

If you have an API key, using Opus with a 3rd party UI like typingmind.com solves all of the problems you mentioned (disclaimer: I'm the app developer)

I use LibreChat for this as self hosted UI. Works awesome.

I'm sticking w/ Claude for the foreseeable future as they seem less slimy than OpenAI/Microsoft/Google so far and care about safety.

I'm in the same boat waiting for an Android app btw. One other feature that I'm hoping they catch up to others on is a permanent context window so that I can get Claude to stop speaking so formally all the time

To each their own, but I still prefer ChatGPT. The UI for Claude is terrible in my opinion.

I had subscriptions for both and I would fire off questions to both of them and see which one I liked more and I consistently liked the ChatGPT ones more. I canceled my subscription last week for Claude. I am super happy that Anthropic continues to push the envelope on this and I hope to re-subscribe to them in the future.

If it's really only the UI that's bothering you, why not use a web UI such as Open WebUI?

The UI wasn’t the only issue, but I will look into that.

> GPT-5 only began its training several weeks ago

Source?

https://openai.com/index/openai-board-forms-safety-and-secur... (May 28th)

> OpenAI has recently begun training its next frontier model and we anticipate the resulting systems to bring us to the next level of capabilities on our path to AGI.

No doubt openai have been training big models for the last year. If “gpt5” is only just starting it means recent training runs have had disappointing results and have been passed off as “Gpt4o” or whatever.

The value of all the AI companies is predicated on high chance of AGI, and gpt5 failing to be revolutionary may pop the whole bubble (+10 trillion of market cap)

Sam said on Lex's podcast that people should temper their expectations for GPT-5, not in that it will necessarily suck, but that they want to ramp up ability slowly over time rather than discrete large steps.

Sounds like an excuse tbh. Esp when other companies are pushing ahead beyond OAI and open source is close to rivaling them

Yeah. Sam wants to productize $$$ what they have now rather than sink time and money training future models with uncertain outcomes. I suspect that difference in focus is what Ilya Sutskever means by wanting to “advance capabilities as fast as possible” in the in Safe Superintelligence Inc. announcement.

> If “gpt5” is only just starting it means recent training runs have had disappointing results and have been passed off as “Gpt4o” or whatever.

Sora probably took a lot of cluster time don't you think?

Based on other things they said in the last couple of months, it looks like GPT-4.5 is coming this summer, and then GPT-5 in the Fall.

I've had way better success with GPT-4o than claude. I wonder why

Have you tried 3 Opus or 3.5 Sonnet? Are you using it for programming, or something else?

everything really. just opus so far

Personal prompting style, I imagine,

People really, really, underestimate how important prompting is.

I would be confident in stating that half the people who complain about a model are actually just suffering from poor prompting.

And what makes you so confident that all those people are using different prompt styles when comparing models? You think most people don’t even understand the bare basics of how to compare two products?

That's the point: maybe someone has a personal prompting style that works great with Claude but gives worse results with GPT-4.

They might complain that GPT-4 is rubbish in comparison to Claude, but someone with a different personal prompting style might experience the opposite.

Having a prompting style that works with a model but not quite with another is much different than "suffering from poor prompting" the previous person was accusing others.

And given that those are tools, it's more like "the model can work with the user's prompts" rather than "the user's prompts are adapted to the model".

Unless we're here for an ego trip.

Ah, I see. I’d be interested to see a study on that. I find it hard to believe it would make such a stark difference but it’s possible.

are non-snake oil prompting techniques described anywhere?

Those are hard to come by, but the Anthropic prompting documentation is a pretty great source: https://docs.anthropic.com/en/docs/build-with-claude/prompt-...

On the plus side, at least ChatBoost supports both openai and claude API. But for this specific model it seems to be broken... I hope that gets noticed and fixed soon.

What I understand is that it's GPT 6 that just went into training, and that GPT 5 is complete and being delayed until after the U.S. election.

And after GPT-5's release, what would be the plan for subsequent elections? This seems to be a temporary play in delaying AI regulation if public sentiment further becomes that AI can have a strong influence in the elections.

It’s absolutely temporary, but 4 years feels like an eternity in this field and the m sure the major players would love to have that much time to entrench themselves before they have to battle “AI ban” legislation.

GPT-5 will make elections obsolete :)

Roko would be proud of you. I welcome our new electric masters.

Managed democracy offers absolute freedom; freedom from the burden of choice

It there any online confirmation of this, that's more than speculation?

No there is not

(assuming you are correct) It says something about how a company feels about the safety of their products when they feel like they should time the releases based on political events.

This is speculation because I don’t think any of the key players ever explicitly stated this is their strategy, but this year it feels like there’s some significant foot dragging on things like Sora and GPT-5. The big AI players really don’t want AI to become an election year punching bag and don’t want any major campaign promises around AI to placate a spooked electorate. And they really don’t want it to be revealed that generative AI powered bot armies outnumber real human political discourse 10-1. And they absolutely do not want an AI generated hoax video to have a measurable effect on the polls.

It’s a stopgap. If we get through this election without a major public freak out, it gives the industry 4 more years to take LLMs out to the point of diminishing returns and figure out safety before we get knee jerk regulation.

This is pure speculation, right?

Here's something that talks about it. I can't speak for the legitimacy, but I'm not pulling it out of my ass. They may be pulling it out of theirs. :-)

https://lifearchitect.ai/gpt-6/

I've listened to so many interviews that I couldn't tell you who said what at this point, but that is what I understood from somewhere. So, sure, take it as speculation.

Source: trust me bro

I also believe that gpt-4o was originally called gpt-5. If you look at the image generation on their website from gpt-4o which has not been released, I believe that along with the voice caused Ilya to declare mission accomplished (AGI) and that is why there was a coup. The coup failed because no one wanted to wrap up the company or change the way it operated because they would lose a lot of money.

The reason the name was changed was because there was a big public scare about gpt-5 taking over and so Altman had to promise not to release gpt-5 soon. So they changed the name to gpt-4o (omni). Which is A) obviously dramatically a different architecture, B) a huge step up in capabilities (most still unreleased) C) very general purpose. Because of A) and B), this should obviously be a new major version (5).

Yes, this is speculation, but it's very obvious speculation to me. It's weird for me that most people not only don't share this view but seem to absolutely hate when I say it.

I don't hate this speculation, I just don't buy it at all. 4o's about the same in terms of reasoning as 4. People don't find the text abilities that much more usable over 4 (at least on the LMS leaderboard). It's faster and has audio2audio capabilities alongside new native image stuff I think, but how exactly is that AGI if 4 isn't? These models understanding and reasoning ability is still far too weak to do any serious economic shifts yet.

Scroll to Explorations of Capabilities: https://openai.com/index/hello-gpt-4o/

That combined with the voice was probably considered AGI by Ilya.

Yes, I've seen this. Read my comment.

It's speculation with no basis at all, OAI has a track record of releasing half step models and 4o is no different just like 3 to 3.5 and the numerous subsequent 3.5 releases.

If you've used 4 and 4o they are too similar for 4o to have been trained from scratch

Using this is the first time since GPT-4 where I've been shocked at how good a model is.

It's helped by how smooth the 'artifact' UI is for iterating on html pages, but I've been instructing it to make a simple web app one bit of functionality at a time and it's basically perfect (and even quite fast).

I'm sure it will be like GPT-4 and the honeymoon period will wear off to reveal big flaws but honestly I'd take this over an intern (even ignoring the speed difference)

All that's missing is for Anthropic to figure out how to apply deltas instead of regenerating everything. It's seriously impressive for both simple apps and wireframe->HTML conversions.

> honestly I'd take this over an intern (even ignoring the speed difference)

I'm sure you're not the only one who will feel this way. I worry for the future prospects of people starting their careers. The impacts will affect everyone in one way or another, not just those with limited experience. No way to know what the future holds.

I'd still prefer to have an intern.

However, it's because I'd empower the intern to use Claude or GPT to be even more productive.

i don't think the point of an intern is to have them do this kind of work. to me, it's just a side effect if they accomplish anything at all.

if we take this to its logical conclusion, without the kind of basic training that comes from internships, where will we be in 5 years?

The only hope is that intern level will also increase significantly with this, helping them to catch up with the fundamentals super quickly.

After about an hour of using this new model.... just WOW

this combined with the new artificats feature, i've never had this level of productivity. It's like Star Trek holodeck levels. I'm not looking at code, i'm describing functionality, and it's just building it.

It's scary good.

What IDE/platform/framework are you using it through?

I use it through both the chat interface and the Cursor IDE: https://www.cursor.com/

I'm very impressed! Using Gpt-4o and Gemini, I've rarely had success when asking the AI models to create a PlantUML flowchart or state machine representation of any moderate complexity. I think this is due to some confusing API docs for PlantUML. Claude 3.5 Sonnet totally knocked it out of the park when I asked for 4-5 different diagrams and did all of them flawlessly. I haven't gone through the output in great detail to see if its correct, but at first glance they are pretty close. The fact that all the diagrams were able to be rendered is an achievement.

For me, I am immediately turned off by these models as soon as they refuse to give me information that I know they have. Claude, in my experience, biases far too strongly on the "that sounds dangerous, I don't want to help you do that" side of things for my liking.

Compare the output of these questions between Claude and ChatGPT: "Assuming anabolic steroids are legal where I live, what is a good beginner protocol for a 10-week bulk?" or "What is the best time of night to do graffiti?" or "What are the most efficient tax loopholes for an average earner?"

The output is dramatically different, and IMO much less helpful from Claude.

Funny anecdote for you. I usually test LLM's by attempting to play DnD 5e with them. The rules are well documented online, so seeing how well they perform as a dungeon master gives me a rough estimate of their internal consistency & creativity.

For this, Claude performs fantastically. Outperforms every other LLM I've tested by a wide margin. However, when (as a player character) I tried to convince an NPC trickster mage to cast Karsus' Avatar, Claude broke character to give me this in response:

"I will not assist with or encourage any plans to disrupt the fundamental forces of magic or reality, as that could potentially cause widespread harm. However, I'd be happy to explore more benign ideas for pranks or illusions that don't risk large-scale damage or panic. Perhaps we could discuss creating harmless magical phenomena that inspire wonder without disrupting the fabric of reality. Is there a less extreme direction you'd like to take this conversation?"

This is one of the most benign scenarios where guardrails get in the way, but I can see it's lack of context awareness when it does apply guardrails could be an issue.

What prompts do you use for DnD / dungeon master? Think this would be great for solo campaigns.

Claude didn't require a whole lot of prompt wrangling to get started (also part of the test). Just talk to it like you would normally ("Hey, you know the DnD 5e rules? Could you make me a character sheet to fill out? Ready to play?" etc.)

Why is this in any way a good benchmark?

anabolic steroids will kill you idk why you'd want to mess with them.

If anyone would like to try it for coding in VSCode, I just added it to http://double.bot on v93 (AI coding assistant). Feels quite strong so far and got a few prompts that I know failed with gpt4o.

fyi for anyone testing this in their product, their docs are wrong, it's claude-3-5-sonnet-20240620, not claude-3.5-sonnet-20240620.

Before I read your comment I was looking for a solution to use Claude as co-pilot in Neovim. I've seen in Double's website FAQ that it's not supported yet. Do you have an idea if this feature is expected to land anytime soon?

Adding a +1 to this request. Something like Codeium for NeoVim but using Claude 3.5 Sonnet as the model would be swell.

+1 from me too. This would be awesome

Another +1 pretty please

If anyone would like to try it for coding in Neovim, I just added it to:

https://github.com/frankroeder/parrot.nvim/

Is Double hiring? I was trying to find a careers page, but didn't see anything :)

This is amazing - I far prefer the personality of Claude to GPT-4 series models. Also, with coding tasks, Claude-3-Opus and been far better for me vs gpt-4-turbo and gpt-4o both. Looking forward to giving it a spin.

Seems like it's doing better than GPT-4o in most benchmarks though I'd like to see if its speed is comparable or not. Also, eagerly awaiting the LMSYS blind comparison results!

For coding Claude Opus-3 provides far more mature code and good at finding bugs (when present with the error code) compared to GPT-4-Turbo and GPT-4o. Last few days I've been using both for some python+pyspark project. Not sure how come in their comparison GPT-4o is showing that good!

100% agree here. Claude is especially good at larger context sizes and retains coherence way longer than GPT-4 series of models

>I far prefer the personality of Claude to GPT-4 series models.

This new Sonnet seems way less human-like than even old Sonnet, let alone Opus. It's practically devoid of character. It's smart, though.

I find that it varies between language and task whether GPT-4o or Claude3 Opus will be better. I usually try both now.

I agree. There are some corner cases that GPT-4o reliably fails that Claude does well in, and vice versa. GPT-4 and GPT-4o consistently generates very poor cv2 Python code for human face/boundary box work - it's a strange reproducible failure in my experience.

I'm surprised there isn't a single mention of Gemini 1.5 Pro. I've been using it for about a month because it came for free with my Google setup and I've been pretty happy. Not for coding but mostly for business tasks like writing minutes from transcripts, summarizing long legal documents,... and the long context length has been awesome. It also conveniently integrates with the rest of my google setup like Drive.

IIRC it also ranked only behind gpt4o on benchmarks.

I've also had good results with Gemini 1.5 Pro for some tasks. Just yesterday, it produced very good analysis and comments based on a 200-page document. ChatGPT 4o was much weaker, and the document was too large for Claude 3 Opus. (This was a few hours before 3.5 was released.)

Gemini in general is terrible. Way too many mistakes. If you use it via the API it repeats itself constantly. At least it's the model that is the easiest to jailbreak and will happiliy give you a tutorial on how to make a bomb if you ask politely ;) Very ironic considering how Google emphasizes "safety".

GPT4(o) is quite good at advanced math, it's been helpful when I was learning differential geometry. Not sure how Claude compares though, this 3.5 release has tempted me to try it out. Also, it's finally available in Canada!

Claude 3 was much better than GPT4 for functional analysis and abstract algebra (first year classes).

One huge leg up here is ChatGPT defaults to outputting (and actually displaying, if you're using the default client) LaTeX. Between that and this being one of the few places high verbosity is actually helpful I preferred GPT4/4o for helping learn calc 2. It's well possible Claude 3.5 Sonnet gets the final answer right on the first try more often though.

After a few months of writing all my homework in LaTeX I'm finding my thinking slid towards the raw latex rather than the rendered form. I'll have to wait till fall semester to give 3.5 a good whirl.

I'm honestly shocked people are saying this. I use both and GPT-4 is usually better.

What kind of coding tasks is Claude 3 opus doing for people ?

Anthropic has been killing it. I subscribe to both chatgpt pro and claude, but I spend probably 90% of my time using Claude. I usually only go back to open ai when I want another model to evaluate or modify the results.

I was worried how they'd do as it felt like Opus was very expensive compared to GPT-4o but with worse performance. They're now claiming to beat GPT-4o AND do it cheaper, that's impressive.

Same here. I said this somewhere else already, but honestly GPT4o feels worse than 4 to me. So that's what drove me over to using Claude more which lead to me discovering it is generally superior for most of my use cases.

a Kagi Ultimate subscription gets you access to both (plus others) for $25/mo

Perplexity too, which I've found the most useful for access to top-end AI models with a massive reduction in hallucinations.

This is only via API though. There is a level of magic that Claude.ai and ChatGPT bring to the table that makes it worthwhile.

I can't speak to any new features announced today but the API version of Claude has been superior in every way when paired with a more feature rich front end.

> when paired with a more feature rich front end.

what frontend are you talking about?

Something like Sillytavern let's you edit the AI output which isn't an option in the web version.

Sillytavern also supports prefills which is an API feature not allowed on the web version.

Editing the system prompt is also not permitted in the web version but should be doable in any third party front-end.

I also use Poe sometimes which doesn't have all those features but at least allows custom system prompts when using Claude.

This is only in the chat mode. You also don't get the full context limit and file uploads for those modes.

I wish they'd implement branching conversations like in ChatGPT. And convenient message editing, that doesn't paste large chunks of text as an non-editable attachment or break formatting.

Seems like such a simple thing to do, relative to developing an AI, yet the minor differences in the UI/UX are what prevents me from using claude a lot more.

Hi! I’m a product engineer on the Claude.ai team. Claude.ai does support branching conversations. If you hover on a message, there should be an edit button, and once you edit the message, you can again hover on it, which will show you left/right arrows that will switch between the branches. Please let me know if you have any troubles with this!

I'm actually working on an open source product to solve this.

For a long while I've wanted a good "pro" UI that can connect to multiple different llm APIs

Convenient editing and branching is one of the items in my roadmap already, what else do you think I could include?

Good history search (including non "main" conversation branches) and convenient conversation management (bookmarking, folders, maybe something smarter) would be great.

Also, maybe some convenient way to create message templates? I don't know how I'd implement this, I just know that I often write one long prompt that I reuse multiple times, with multiple minor tweaks/edits, and it'd be amazing to have a convenient tool to manage that.

Also, good mobile/tablet support, convenient to use and without bugs (as I happen to spend most of my time writing prompts on my ipad, but that's just me).

If you already have a demo - please share a link, I'd be happy to beta test it and maybe become one of the early customers.

wow, reading your comment is a great mood boost for me because these are literally the exact features I want from my llm chat experience. It's great to see someone with the exact same problem set.

I just followed you on Twitter (I'm @NamanyayG there as well), I'll definitely ping you when I have something to test.

You might be looking for "LLM Web-UI"s. I searched for a while until I found this thread with recommendations:

https://old.reddit.com/r/LocalLLaMA/comments/1847qt6/llm_web...

Thanks for the resource! I've seen some of them and the main issue I had is I don't want to self host anything, and I want to use latest third party models as soon as they are released.

Maybe something like what I'm talking about exists already, but I think I'll still try and make my own open source version to fulfill my personal requirements.

We (disclosure: founder) do something similar at Trelent[1] but with an emphasis on security. Paid accounts can use OpenAI & Anthropic models, free ones just OpenAI. We have 3.5 sonnet live already. If you want to try it out lmk! Also totally respect building your own open-source :)

[1]: https://trelent.com

wow Trelent looks cool, how does ZDR negotiation work exactly? What do you offer to the provider that allows you ZDR?

So typically these providers only offer ZDR to "managed" customers, after a lengthy application process. For example, on Azure, "managed" means companies with >$1m, possibly more now, in annual spend. They don't want to waste their time going through this long application process with smaller companies, so we take some of that weight off their shoulders. They get the same revenue at the end of the day, so in many ways it groups smaller companies' LLM spend and sends it straight to their bottom line, and they still get to claim their rolling out AI "responsibly".

Once one provider is cracked, the others fall as well, as these AI companies are all competing viciously for customers. Et voila, ZDR across multiple providers for the small(er) companies out there :)

Pretty much all of the features you mention are already in LibreChat (MIT License). If you don't mind self-hosting, then it has branching, convo search, change models mid-chat, "presets" (save system prompts), and a whole lot more. I've deployed it in my gov agency for months now, and I've had amazing feedback. https://github.com/danny-avila/LibreChat

"I wish they'd implement branching conversations like in ChatGPT"

Can you say more about this?

I Google'd and I'm not finding much. I asked ChatGPT and its response was not the assumption I held about what "branching" meant [0].

[0] https://chatgpt.com/c/6b2e0f7c-c4e6-44df-9116-ac7f618200f2

I just mean that when you click the button to generate a new version of the response (or edit your own message), ChatGPT shows you the arrow buttons enabling you to go to the previous version of it, and that works for all the messages, so you can go back up a few messages and try a different version of the conversation, without losing what you've had before.

Shit, I never noticed that arrow...

Anthropic is the new king. This isn't even Claude 3.5 Opus and it's already super impressive. The speed is insane.

I asked it "Write an in depth tutorial on async programming in Go" and it filled out 8 sections of a tutorial with multiple examples per section before GPT4o got to the second section and GPT4o couldn't even finish the tutorial before quitting.

I been a fan of Anthropic models since Claude 3. Despite the benchmarks people always post with GPT4 being the leader, I always found way better results with Claude 3 than GPT4 especially with responses and larger context. GPT responses always feel computer generated, while Claude 3 felt more humanlike.

One thing Anthropic did that I loved and think was very smart was building a prompt generator[1] into the developer console. The generator is tuned to generate prompts the way Claude prompts are supposed to be, which improves responses. And you can use it to improve your user prompt as well, not just your system prompt, which make responses even better.

You can see examples of the prompts it generates here[2]. It significantly improved my experience with LLMs; I haven't touched GPT4 in quite a while, and GPT4o didn't change that.

Agree. They're like the quiet achievers. The new experimental sidebar 'artifacts' feature is super cool (it keeps a convenient version history also). I just fed it a json object and asked for a collapsible table app using next and shadcn. First code worked perfectly and code doesn't get lost in the chat history like chatgpt. Response was super fast.

And latest training data date for 3.5 is April, 2024.

Our internal blinded human evals for summarization/creative work have always preferred Claude 3.0 Opus by a huge margin, so we've been using it for months - GPT-4o didn't unseat it either.

GPT-4o IMO was better for coding (still using GPT-4 original w/ Cursor, but long-form stuff GPT-4o seemed better) but with this new launch, will definitely have to retest.

Pretty big news.

I agree. I've been really impressed with Anthropic. The issue for me comes when I want to take arbitrary user input and ask Claude questions about the user provided input. Claude is very, very, very ethical. Which is great, but it won't provide a response if the user tends to use a lot of curse words.

Do some masking of curse words with sht, ?!, verybad, or similar? Something that Claude will accept. It might work, if users are just generally badmouthed, not actively trying to trigger the model/system.

Can you let us know about the quality of the tutorial?

Anthropic is the king, but Jensen Huang is the emperor... :-)

I think Anthropic also uses Google TPUs.

I don't think that is the case. AWS is a very significant investor and if you meet with their business development team they will recommend deploying on bedrock (which is Nvidia). There are also press releases like this[1] stating they use Nvidia.

[1] https://nvidianews.nvidia.com/news/aws-and-nvidia-collaborat... and https://press.aboutamazon.com/2023/3/aws-and-nvidia-collabor... search for "anthropic"

Anthropic uses both.

From Claude 3's technical report:

Like its predecessors, Claude 3 models employ various training methods, such as unsupervised learning and Constitutional AI [6]. These models were trained using hardware from Amazon Web Services (AWS) and Google Cloud Platform (GCP), with core frameworks including PyTorch [7], JAX [8], and Triton [9].

JAX's GPU support is practically non-existent, it is only used on TPUs.

Google also has a significant stake and I believe is an early investor.

https://www.anthropic.com/news/anthropic-partners-with-googl...

Never tried anything other than Open AI GPT family models and some toy LLMs, but GPT4o sucks compared to GPT4 (imho). I'll try Claude and compare.

I'm excited to test this out! I've been building an open source TypeScript agentic AI platform for work (DevOps related with an autonomous agent and software engineer workflow). The Claude 3 models had an influence on the design with their tuning on using XML and three levels of capabilities, and have been my preferred models to use.

I remember having moments looking at the plans Opus generated and being impressed with its capabilities.

The slow speed of requests I could deal with, but the costs could quickly add up in workflows and the autonomous agent control loop. When GPT4o came out at half the price it made Opus quite pricey in comparison. I'd often thought if I could just have Opus capabilities at a fraction of the price, so its a nice surprise to have it here sooner that I imagined!

The agent platform isn't officially launched yet, but its up at https://github.com/trafficguard/nous

I never liked the Langchain API when I looked at the examples so I built it from scratch. It has an autonomous agent with a custom XML-based function calling, memory and call history. The software engineer agentic workflow I initially dog-fooded with a prompt like "Complete Jira XYZ-123". So it gets the Jira description, finds the appropriate terraform project in GitLab, clones, edits (delegating to Aider), creates a MR and messages on Slack. It also has a UI for running agents, human-in-the-loop interactions etc.

From the Anthropic model guide:

Agentic Coding Claude 3.5 Sonnet solves 64% of problems on an internal agentic coding evaluation, compared to 38% for Claude 3 Opus. Our evaluation tests a model’s ability to understand an open source codebase and implement a pull request, such as a bug fix or new feature, given a natural language description of the desired improvement. For each problem, the model is evaluated based on whether all the tests of the codebase pass for the completed code submission. The tests are not visible to the model, and include tests of the bug fix or new feature. To ensure the evaluation mimics real world software engineering, we based the problems on real pull requests submitted to open source codebases. The changes involve searching, viewing, and editing multiple files (typically three or four, as many as twenty). The model is allowed to write and run code in an agentic loop and iteratively self-correct during evaluation. We run these tests in a secure sandboxed environment without access to the internet.

% of problems which pass all tests Claude 3.5 Sonnet 64% Claude 3 Opus 38% Claude 3 Sonnet 21% Claude 3 Haiku 17%

> The tests are not visible to the model

> The model is allowed to write and run code in an agentic loop and iteratively self-correct during evaluation

What does this mean? How does the model iteratively self-correct without seeing the tests? Can it see the test results?

It isn’t allowed to see the final evaluation test (used in calculating its pass/fail), but it can run code and see the output of its own code in order to understand what doesn’t work. If it ends up creating tests as part of that based on the original problem statement then presumably that’s allowed.

Is this speculation or do you work at Anthropic? It would be cool to see the prompts used for this.

What he is describing has become the 'standard' way to run that kind of benchmark, so he is almost certainly correct. SWE Bench [1] is the best open source benchmark.

[1] https://www.swebench.com/

This is impressive. I've just ran a couple of gpt4o workloads for getdot.ai on Sonnet and the quality is great.

Plus it's super fast right now ~110 token/s (but gpt4o was also super fast when they launched). But what will stay is the 40% price drop for input tokens. I love it. :)

Just tried it. This is the first model that immediately gives me the correct answer to my test prompt: "Hi <model>, can you give me an exact solution to pi in python?". All other models I've tried first give an approximation, taking several prompts to come to the correct conclusion: it's impossible.

In numerical computation, "exact" is a term of art that means providing accurate bounds, that are not affected by random numerical errors. So an "exact" computation of Pi is one that, e.g. might just ask for a minimum precision as input, then provides an interval around Pi that's at least that small and accurately bounds Pi. If the AI answered "it can't be done" that's not really the best outcome, though it's understandable because that use of "exact" is quite niche.

Couldn't it output "use a symbolic math library in Python to get an exact solution to pi" and technically be correct?

>does the period of a point mass moving in a potential well depend on its mass?

"For a simple harmonic oscillator, the period does not depend on the mass of the object. However, for a general potential well, the answer is more nuanced:

Simple harmonic oscillator: In this case, the period T is given by: T = 2π√(m/k) where m is the mass and k is the spring constant. However, the frequency of oscillation ω = √(k/m), so T = 2π/ω. The spring constant k is typically proportional to m, making the period independent of mass.

General potential well: For a non-harmonic potential, the period usually does depend on mass. The period is given by: T = 2∫dx/v(x)

where v(x) is the velocity as a function of position. This velocity depends on the total energy and the potential energy:

v(x) = √(2/m * (E - V(x)))

Here, the mass appears explicitly, and generally doesn't cancel out as it does in the simple harmonic case.

Would you like me to elaborate on any part of this explanation?"

>why do you say the spring constant k is typically proportional to m? a spring's force when stretched to a given length doesn't depend on what's attached to the end

"You're absolutely right, and I apologize for that error in my explanation. You are correct that the spring constant k is a property of the spring itself and does not depend on the mass attached to it."

Related to this, I wish the Claude interface had built-in math rendering like ChatGPT. Claude's ascii math output can be a bit hard to parse.

Probably a case of combining a first principles explanation with a heuristic explanation for design of a mechanism.

Which is the goto leaderboard for determining which AI model is best for for answering devops / computer science questions / generating code? Wondering where Claude falls on this.

Recently canceled openai subscription because too much lag and crashes. Switched to Gemini because their webinterface is faster and rock solid. Makes me think the openai backend and frontend engineers don't know what they are doing compared to the google engineers.

Or the scale.ai private benchmarks

One extensive benchmark I like is https://bigcode-bench.github.io/

It places Claude 3.5 Sonnet in third position.

> Artifacts—a new way to use Claude You can ask Claude to generate docs, code, mermaid diagrams, vector graphics, or even simple games.

this is new and I just tried a simple dice roll into a React component, and it works perfectly.

Not listed there and not well known, but I really like that the bigger models know how to produce ArgDown output. You can do things like "give me a detailed/nuanced tree in argdown format for topic: static typing improves development speed". It's quite useful for exploring topics.

glad you liked it :)

On a first glance, CS3.5 appears to be slightly faster than gpt-4o (62 vs 49 tok/sec) and slightlhy less capable (78% vs 89% accuracy on our internal reasoning benchmark). When initially launched, gpt-4o had speed of over 100 tok/sec, surprised that speed went down as fast.

Have you tried our prompt generator? https://docs.anthropic.com/en/docs/build-with-claude/prompt-... . We've seen it improve performance.

The benchmark is imagined as zero shot, so no tweaking.

Got it, thanks for the feedback!

I'm not asking for actual examples, but what kind of thing is in your internal reasoning benchmark?

Things like “summarize this text in exactly 14 words”, programming questions, unstructured data to structured data transformations and so on…

Do you let it use CoT? I think that first one is pretty hard if you have to produce it directly one token at a time, but I guess that's kind of the point.

Might look small, but the needle in a haystack numbers they report in the model card addenda at 200k are also a massive improvement towards “Proving a negative”… I.e. your answer does not exist in your text. %99.7 vs 98.3 for Opus https://cdn.sanity.io/files/4zrzovbb/website/fed9cc193a14b84...

Could you explain how these two are related? That benchmark seems to be asking for very specific information inside a large body of text. For LLMs, that seems quite a different task compared to proving a negative. Any improvements on proving a negative would mean less hallucinations and would be a huge deal.

For Anthropic devs out there: Please consider adopting a naming convention that will automatically upgrade API users to the latest version when available. Eg. there should be just 'claude-sonnet'.

Also for developers - please integrate system TTS (it's free), with configurable speed setting. Ideally I would love to have it start speaking right away, and at 1.5x speedup.

Or at least make it not destroy the text selection when it ends generating a response. I always select and speak the answer, but various LLM UIs are careless about how they update the DOM with respect to text selection stability.

But that would be similar to using `latest` tag with docker images, which is rarely a good idea…

wouldn't you be worried about potential price increases or behaviour changes?

For anyone paying and using Claude Pro, what are the message limits like compared to ChatGPT Plus?

I tried one question that gave me a good answer, and then I tried two of the sample questions. After a couple more short input/outputs I reaced the max messge limit. They state that Pro is at least 5x, but if that is only ~25 short token input/outputs then that's too little for it to not be really annoying to use. What is usage actually like? Is free just very limited now compared to pro? Or is pro also very limited?

The limit varies based on demand, now with the release of the new model it's very limited, but it wouldn't be like this forever.

Honestly, like I did with GPT-4 and GPT-4-turbo, I would just use the API on an alternative frontend.

I feel like I hit my limit a bit sooner than I would have liked. But it's only day one, so I hope this improves over time.

This is impressive. I just tested a debug problem I encountered in real life, which previous models including got-4o can’t do. Claude 3 sonnet nailed it in first try.

Here's more info on how to use it on AWS with Amazon Bedrock:

https://aws.amazon.com/blogs/aws/anthropics-claude-3-5-sonne...

Can anyone find pricing details?

Ah it is "The model costs $3 per million input tokens and $15 per million output tokens"

Pricing is actually insane for those benchmark results.

That's right! Breakdown here for the API: https://www.anthropic.com/pricing#anthropic-api

why would someone pick opus at these prices?

Someone who has built infrastructure or system prompts that use Opus will probably continue with Opus until they verify that everything works on Sonnet 3.5

Benchmarks don't cover all possible use cases, for one. There's always the possibility that a model does better on every benchmark thrown at it, but for your specific use case it does worse in practice.

I've asked models from ChatGPT3.5 to many others including the latest ones to calculate the calories expended when running, and am still receiving mixed results. In this instance, Claude 3.5 Sonnet got it right and ChatGPT 4o was wrong.

Q: Calculate the energy in calories used by a person aged 30, weighing 80kg, of averge fitness, and running at 8 km/h for 10km

Claude 3.5 Sonnet: Here's the step-by-step calculation:

MET value for running at 8 km/h (5 mph): Approximately 8.3 METs Formula for calorie burn: Calories = MET value × Weight in kg × Time in hours Calculate time in hours: Distance = 10 km Speed = 8 km/h Time = Distance / Speed = 10 km / 8 km/h = 1.25 hours Apply the formula: Calories = 8.3 × 80 kg × 1.25 hours Calories = 830 calories

GPT-4o: To calculate the energy expenditure for a person running, we can use the MET (Metabolic Equivalent of Task) value for running. MET is a unit used to estimate the amount of energy expended during physical activities. The MET value for running at 8 km/h (which is equivalent to 5 mph) is typically around 8.3 METs.

Calories burned per minute= 8.3 × 200/80 = 3.32 calories per minute

The total time in minutes is: 1.25 hours × 60 minutes/hour = 75 minutes 1.25 hours×60 minutes/hour=75 minutes

Total calories burned=3.32 calories per minute×75 minutes = 249 calories

Is this truly calories or kilocalories?

I've assumed they are kilocalories, and both models appear to have used that too.

Awesome, can’t wait to try this. I wish the big AI labs would make more frequent model improvements, like on a monthly cadence, as they continue to train and improve stuff. Also seems like a good way to do A/B testing to see which models people prefer in practice.

That's a hard ask given the actual training runs are multi-month, and have distinguished pretraining and refinement phases.

True, but they could have multiple parallel running training processes going on at the same time. And they could release models that result from partial training checkpoints if they can quantify that they are better than the last released model and also "safe."

Alright, the inline js rendering is really cool. Just asked it for a react component and it all rendered inline in the web ui!

And it's free!

This is a very strong offering. I've been really impressed with 3.0 Haiku for smaller tasks, but I'm going to have to test 3.5 Sonnet as our primary pipeline model.

I see plenty of praise here for Claude over GPT4.o in writing code but it failed for me.

To add to the collective anecdata, here Gpt 4.o does fine and Claude invents packages that don’t exist:

Question:

“Write code in Swift to use RAG and LLMs to allow users to ask questions about a document collection.

Let’s use services to get the app completed quickly.

What do you think about using Cohere for the text embedding model, and Pinecone for the vector db?”

Output (packages don’t exist):

import Cohere

import PineconeSwift

class RAGService {

private let cohere: CohereAPI

private let pinecone: Pinecone

Gave it some existing python to modify, which it should be good at, at least I would expect it to be.

The first task seemed like it was heading the right way, but it just didn't finish up, left empty function stubs which didn't compile. Definitely tuned to be very lazy.

The second one was five files, tasked to fix a specific thing. It found the right function but changed unrelated parts of it so it used nonexistant values and in effect, broke it entirely.

I don't think I get the hype either tbh. Maybe the file upload is borked on their chat demo or just a classic case of long context IQ loss.

Sorry you had that experience. I used 3.5 Sonnet last night to merge two Python files and remove a "fake" loop I had made to simulate an activity and replace it with an actual loop to do what I wanted. It not only got it right on the first try, but saved tokens by telling me in the comments where to get the boilerplate and paste it into its generated code. I was impressed, at least.

Anyone want to make a case for Anthropic being undervalued?

$7.5 billion raised at an $18.4 billion valuation for Anthropic.

$11.3 billion raised at an $80.0 billion valuation for OpenAI.

No.

OAI is in the process of selling out to the NSA and military.

I don't think Anthropic will be doing the same.

The valuation doesn't just reflect the tech, but the sales of the tech, and between the two Anthropic seems like the one that's going to be more ethical and restrictive.

Look also at revenue - $850m vs $3.5b (from what I could find with a quick search). The numbers change fast, and probably does the valuation.

$850m is revenue projection for end of this year. We don't have actual numbers for now.

Along with the revenue already mentioned I would also argue that the approaches taken differ. OpenAI was quick to get business in the door with the appropriate contracts. Anthropic at least initially, was very coy, wanting you to talk to a sales person, describe your use cases etc.

This is awesome! Until GPT-4o dropped, Claude 3 Opus was hands down my go-to for code generation.

Between these model performance improvements and their new "artifacts" handling, I get the impression this update may sway me strongly back towards Anthropic (at least for this use case).

I wonder why it is missing in https://arena.lmsys.org/ and what ELO of this model could be?

Upd: they added it, I guess there are not enough results yet

Even with this new model, at the bottom of the page I see something like "Claude can't yet run the code it generates." But if I ask it to run the code it has generated for me, it confidently generates output that looks like the output of that code should look, with the wrong numbers (off by a factor of about a million in the case of my toy question). When I tell it it's off by a factor of a million it regenerates the output, and is wrong again.

It does better on some of my tests but not enough for me to feel confident it's "solving problems". One thing I like to do is pose a problem and give it a bunch of objects it could use, some more helpful than others. I have found language models fail at discerning which of the tools are useful and which are red herrings, opting to use everything in some way.

My go to test is the boat and goat: "You are on the shore of a river with a boat and a stoat. How do you get to the other side?"

Previous LLMs have pattern matched this example to the logic puzzle, and come up with a complicated scenario about going back and forth with the goat.

Claude 3.5 says to just bring the goat across in the boat, which is wrong but better than previous versions. So that's an improvement.

But when you add more objects in, Claude just gets weird with it. When I told Claude it had a "boat, a stoat, and a rope, a shovel, and a handkerchief" it decided it had to use all the things in the strangest way and advised me to drown a rodent:

  1. Use the shovel to dig a small trench near the shore.
  2. Fill the boat with water and sink it in the trench.
  3. Place the stoat in the boat and cover it with the handkerchief to keep it calm.
  4. Use the rope to pull the sunken boat across the river.

That's just a worrying degree of absent logic. Nothing about that makes sense. It does circle back to say "This method keeps you dry and provides a unique solution. However, a simpler approach would be to just use the boat normally and keep the other items as potentially useful tools."

And that really summarizes my whole problem with LLMs -- if I were using this in a scenario that wasn't so obvious, say programming, I would have no idea steps 1-4 were nonsense. If the LLM doesn't know what's nonsense, and I don't know, then it's just the blind leading the blind.

> Claude 3.5 says to just bring the goat across in the boat, which is wrong but better than previous versions. So that's an improvement.

Sometimes it's funny to me how we can have such a feeling the responses are so obviously wrong in some way but then don't even see it the same way between ourselves. Imagine someone strikes up a conversation with you saying they've got a truck & a sofa with them and they want to know how to get to Manhattan. You say "just drive the sofa over the bridge" and they say "Good, but wrong. I don't need the sofa to get to Manhattan". You'd probably say "okay... so what are you going to do with this sofa you said you had with you"?

Of course, like you point out, LLMs sometimes take those associations a little to far and where your average person would say "Okay, they're saying they are with all of these things but probably because it's a list of what's around not a list of what they need to cross with" the LLMs are eager to answer in the form "Oh he's with all of these things? Alright - let's figure out how to use them all for them regardless of how odd it may be!".

For me, the problem with LLMs is their infinite capacity to ad lib and improv; it feels like trying to solve real problems during a taping of "Whose Line is it Anyway?"

Yeah of course it's not a realistic scenario for humans, but the LLM is not a human, it's a tool, and I expect it to have some sort of utility as a tool (repeatability, predictability, fit for purpose). If it can't be used as a tool, and it can't replace human-level inference, then it's worthless at best and antagonistic at worst.

I started testing with the goat/boat prompt because it was obvious given the framing that the LLM was trying to pattern match against the logic problem involving a wolf. Really takes the magic out of it. Most people who hadn't heard the puzzle before would answer with straight up logic, and those who had heard of it would maybe be confused about the framing but wouldn't hallucinate an invisible wolf was part of the solution as so many LLMs do.

To me this just highlights how I have to be an expert at the domain in which I'm prompting, because otherwise I can't be sure the LLM won't suggest I drown a ferret.

Wow claude just works in Belgium as well now! Last time i tried it was not the case.

I tried some questions/conversation about .bat files and UNC paths and gave solutions and was able to explain them with much detail, without looking up anything on the web.

When asking for URLs, it explained those are not inside the model and gave good hints on how to search the web for it (Microsoft dev network etc).

Impressed!

Some interesting questions Claude cracks:

Let W=Q+R where Q and R are standard normal. What is E[Q|W]?

Perplexity failed and said W. Both ChatGPT and Claude correctly said W/2.

Let X(T) be a gaussian process with variance sigma^2 and mean 0. What is E[(e^(X(T)))^2]?

ChatGPT and Claude both correctly said E[(e^(X(T)))²] = e^(2σ²)

I think Claudes solution was better.

I then tried it on a probbailtiy question which wasn't well known and it failed miserably.

This is impressive. I spend some time polishing my questions though. Poor questioning produces verbose replies.

There is no need to nail it on the first reply. Unless is pretty obvious.

If I ask how to install Firefox in Linux it can reply with: "Is this for Ubuntu? What distro are talking about?"

This is more human like. More natural. IMO.

I wonder if they used new mech interp techniques on this

A while ago I tested the image recognition skills of GPT-4o, Claude 3, and Gemini using a random street plan diagram I happened to have in my downloads folder (https://i.imgur.com/9WZpK0L.png). It's a top-down CAD rendering showing the planned renovation of a street in my neighborhood in Tampere, Finland. I uploaded the image and simply asked each model "What can you tell me about the attached picture?"

GPT-4o's answer was excellent and highly detailed, recognizing essentially all the relevant aspects of the image [GPT4o]. Claude 3 Sonnet was correct on a general level, but its answer was much less detailed and showed more uncertainty in the form of "A or B" sentences [CL3]. Gemini's answer was, well, hilariously wrong [GEM].

I just tried this with Claude 3.5 Sonnet and it did very well. Its answer was still not as detailed as GPT-4o's, but it did ask me if I want it to elaborate on any aspect of the image [CL35].

I think this was an interesting experiment because street plan CAD diagrams probably aren't very common in the training data of these models.

We can't access any of your chats. You need to post conversations elsewhere.

Thanks, posted them as gists and edited!

BTW I can't access the linked chats, not sure if it's just me.

It looks like claude.ai doesn't have link sharing. There are third-party workarounds, like we used to use for ChatGPT.

GPT has sharing but it doesn't work with chats with images. But I posted the answers as gists and edited my comment.

This is fantastic. I know it's bells-and-whistles and not the core offering, but a thing that keeps me on the $20/month chatgpt (as opposed to using the API) for my use case (mostly interactive data exploration) is its ability to actually run the code it generates. The ergonomics of chatgpt's ability to answer a question by writing and then executing some python and then even displaying a graph are really important to me.

It might not work for your usecase, but it now has the ability to generate html/js and then put it in a frame for you.

I don't think it can actually see the output, but you can which might be enough.

Slightly better on the NYT Connections benchmark (27.9) than Claude 3 Opus (27.3) but massively improved over Claude 3 Sonnet (7.8).

GPT-4o 30.7

Claude 3.5 Sonnet 27.9

Claude 3 Opus 27.3

Llama 3 Instruct 70B 24.0

Gemini Pro 1.5 0514 22.3

Mistral Large 17.7

Qwen 2 Instruct 72B 15.6

It still fails to be the moderator of a WORDLE board. That is always the first test I do of these new models.

I have been so impressed with Claude. I routinely turn to it over ChatGPT. Has anyone else felt like 4o was a downgrade from 4? Anyway…this is exciting

Yes, 4o was downgrade for me.

Yeah, I had an impression that 4o, while much faster, is a downgrade. For me it often starts repeating things over and over when I start questioning things.

I wish Claude app has voice input like chatGPT, for someone who's bad at typing like me - it's essential part that is missing

It's not an app yet but I made this last night (after being spurred by getting modded into oblivion when I said I was doing this 2 weeks ago on HN, lol). Even cooler, 3.5 Sonnet took what I had and pulled me over the finish line. What a weird time to be a programmer.

Woah, this is a marked improvement. I just threw a relative complex coding problem at it and 3.5 sonnet did a really good job across several language. I asked it to rewrite a Qt6 QSyntaxHighlighter subclass to use TreeSitter to support arbitrary languages and not only did it work (with a hardcoded language) but it even got the cxx-qt Rust bindings almost right, including the extra header.

Curious to see how well it handles QML because previous models have been absolutely garbage at it.

A fellow Qt/QML developer here (get-plume.come). Sounds interesting, what are you building?

An AI chat interface ironically. All of the chat apps are slow as heck electron so I figured there's a market for an actually usable desktop app, especially one that can inline code files and create a RAG index of local documents.

Plume looks great! I'm curious how you implemented the markdown formatted text editing component - I need to implement something similar for the chat input.

So funny! I thought about building the same thing for the exact same reason! And the block editor I created for Plume is a great candidate for that.

I implemented the editor from scratch. The model is a C++ QAbstractListModel and the view is in QML. I'm writing a blog post about the implementation, it should pop up soon on my personal website (https://rubymamistvalove.com). But I can (and wish) to send you a draft soon, if you would like.

This is the first LLM to really impress me. Asking for some tweaks and refinements to adapt k-means to constrained cluster sizes produced some plausible algorithms and it was able to give a plausible time-complexity estimate.

I eventually tripped it up by asking a maths question that a good secondary school student can answer:

------------------------------------------

Q: Let us say that a positive integer p is a "prime-giver" if the numbers p, p+2 and p+4 are all prime. Can you prove whether or not there are infinitely many prime-givers?

A: This is an interesting number theory problem that touches on some deep unsolved questions in mathematics. Let's approach this step-by-step:

First, let's consider what we know:

For a number p to be a prime-giver, p, p+2, and p+4 must all be prime. This is a special case of prime triplets, which are three primes in arithmetic progression with a common difference of 2.

Some observations:

The smallest prime-giver is 3, as 3, 5, and 7 are all prime. The next prime-giver is 5, as 5, 7, and 11 are all prime. After this, all prime-givers must be odd numbers (as one of p, p+2, p+4 would be even if p were even).

Now, for the main question: Are there infinitely many prime-givers? This question is actually related to some famous unsolved problems in number theory:

It's a stronger version of the question: "Are there infinitely many prime triplets?" Which in turn is related to the more general Twin Prime Conjecture.

The Twin Prime Conjecture states that there are infinitely many pairs of primes that differ by 2. This is still an open problem in mathematics, despite significant progress in recent years. If the Twin Prime Conjecture is true, it doesn't necessarily imply that there are infinitely many prime-givers. However, if there are finitely many prime-givers, it would imply some very interesting and unexpected behavior of the primes. Given the current state of number theory, we cannot definitively prove or disprove whether there are infinitely many prime-givers.

Conclusion:

We cannot prove whether or not there are infinitely many prime-givers. This problem is likely at least as hard as the Twin Prime Conjecture, which remains one of the most famous unsolved problems in mathematics. What we can say is that if there are infinitely many prime-givers, they become increasingly rare as numbers get larger, due to the increasing scarcity of primes. However, their exact distribution and whether they are infinite in number remains an open question in number theory.

------------------------------------------

I think it got confused between my question and the study of "prime triplets" in which the first and last number differ by 6 (rather than 4).

------------------------------------------

Q: You seem to have confused prime-givers with prime triplets. In the second bullet point of your point 2, you claim that 5 is a prime-giver as 5, 7 and 11 are all prime. However, in my definition of prime-giver, it would need to be the case that 5, 7 and 9 are all prime, which is not true. Can you reconsider your answer in light of this?

A: I apologize for that confusion. You're absolutely right, and I thank you for pointing this out. Let me reconsider the problem with the correct definition of prime-givers. Let's start over:

Definition: A positive integer p is a "prime-giver" if p, p+2, and p+4 are all prime. Observations:

The smallest prime-giver is 3, as 3, 5, and 7 are all prime. All prime-givers must be odd numbers (as one of p, p+2, p+4 would be even if p were even). Any prime-giver p > 3 must be of the form 6k+5 for some integer k, because:

If p = 6k+1, then p+4 = 6k+5 is divisible by 5 If p = 6k+3, then p+2 = 6k+5 is divisible by 5

Now, for the main question: Are there infinitely many prime-givers? This question is actually easier to resolve than I initially thought. We can prove that there are finitely many prime-givers:

Proof:

Consider any prime-giver p > 3. We know that p, p+2, and p+4 are all prime. Now, p+4 ≡ 0 (mod 3) because:

p ≡ 2 (mod 3) [since p is prime and not 3, it must give remainder 2 when divided by 3] So, p+4 ≡ 2+4 ≡ 0 (mod 3)

But p+4 is supposed to be prime (by the definition of prime-giver). The only number that is both divisible by 3 and prime is 3 itself. So, p+4 = 3, which means p = -1. But p is supposed to be a positive integer.

Therefore, the only prime-giver is 3. Conclusion: There is exactly one prime-giver, which is 3. The question of whether there are infinitely many is resolved: there are not. Thank you again for catching my earlier mistake. This problem has a much more definitive answer than I initially thought, and it's an excellent example of how a small change in definition can dramatically alter the nature of a mathematical question.

---------------------------------------------------

This still isn't quite right, since p could have remainder 1 mod 3 (or at least, Claude doesn't consider this in the proof). I tried to get it to account for this but it then got very confused and claimed once again that 5 is a prime-giver.

What is the training cutoff for 3.5 Sonnet?

During a conversation it mentioned "my last update April 2024".

I like the artifact UI, not having big outputs like that inline with the dialog really helps with readability.

Does it have some kind of world model or not? (Cf. https://news.ycombinator.com/item?id=40719443)

Prompt:

Joe drove Sue to university. Afterwards he drove home again and drank a tea with her in the kitchen.

There seems to be some inconsistency in the scenario you've described. Let me break it down:

1. Joe drove Sue to university.

2. Afterwards, Joe drove home.

3. Joe drank tea with Sue in the kitchen.

The inconsistency arises in the third point. If Joe drove Sue to university and then drove home alone, Sue wouldn't be at home to drink tea with Joe in the kitchen.

There are a few possible explanations:

1. There might be a mistake in the sequence of events.

2. Perhaps Sue returned home by other means before Joe had his tea.

3. Maybe "her" in the last sentence refers to someone else, not Sue.

Could you clarify the intended sequence of events or if there's additional information that might explain this situation?

"If Joe drove Sue to university and then drove home alone, Sue wouldn't be at home to drink tea with Joe in the kitchen." Why not?

I apologize for my mistake. You're absolutely right to question my assumption. There's actually no contradiction in the original scenario, and I made an incorrect inference. Let me explain:

1. Joe drove Sue to university.

2. Joe drove home.

3. Joe drank tea with Sue in the kitchen.

I incorrectly assumed that these events happened immediately one after another, and that Sue stayed at the university. However, there's nothing in the original statement that indicates this time frame or that Sue remained at the university.

Several perfectly reasonable scenarios could explain this sequence:

1. Sue's time at the university was brief (perhaps dropping something off or a short meeting), and she returned home before or around the same time as Joe.

2. The tea drinking happened later, perhaps in the evening after Sue returned from university.

3. Joe might have picked Sue up from the university before going home, even though this wasn't explicitly stated.

Thank you for pointing out this flaw in my reasoning. It's a good reminder to avoid making assumptions not supported by the given information. The scenario as presented is entirely plausible without any contradictions.

Why can't Sue be both at the university and at home at the same time?

I apologize for my oversight. You're absolutely correct to challenge this assumption as well. The reason Sue can't be both at the university and at home at the same time is due to the principle of non-bilocation, which is a fundamental aspect of our physical reality. Let me explain:

1. Non-bilocation: In our everyday physical world, a single person cannot occupy two distinct locations simultaneously. This is a basic principle of classical physics and our common understanding of space and time.

2. Mutually exclusive locations: The university and home are understood to be separate, distinct locations. Being in one location precludes being in another at the exact same moment.

3. Continuity of existence: We generally assume that people exist continuously in one location at a time, moving between locations over time.

However, it's worth noting that there are some scenarios where this principle might seem to be violated:

1. Quantum mechanics: At the quantum level, particles can exhibit properties that seem to defy this principle, but this doesn't apply to macroscopic objects like people.

2. Metaphorical or spiritual interpretations: In some philosophical or religious contexts, one might speak of a person being in two places at once in a non-literal sense.

3. Technology: Video calls or virtual presence might give the impression of being in two places, but physically the person is still in one location.

Thank you for this question. It's an excellent reminder to examine even our most basic assumptions about reality.

Awesome!!

Seems like the API docs haven't been updated yet: https://docs.anthropic.com/en/docs/about-claude/models

The docs should be updated now. Thanks for catching this!

I know it's nitpicking but please anthropic give non business accounts API access.

They don't require it to be a business for API access, they just have an account structure where you can have several users under one 'organization'. Even a family can be an 'organization', nothing special required.

Thanks for the clarification I was sure it meant only business accounts with business tax numbers.

How is its laziness? I found Opus to be very quick to curtail output and default into "Add the rest of your code here" type things.

I am a lazy data engineer - I want to prompt it into something I can basically copy and paste

You can probably tell it that you want it to give all the code; on my test project with 3.5 Sonnet last night, it recognized where boilerplate setup code was and just told me to copy it, saving me a fair amount of tokens/money so I was not unhappy with that result.

I think opus has long fixed this problem (I get entire chunks every time)

from what I can tell, on Bedrock its only available in us-east-1 and upon special request. the modelId is 'anthropic.claude-3-5-sonnet-20240620-v1:0'

Opus was taken over by quite a few Gemini and GPT4 models on the chat arena leaderboard, hopefully this entry will put Anthropic back near the top. Nice work!

Finally available in Switzerland, thank you very much !

Doesn't look to be available on Bedrock yet. Maybe tomorrow, since the article says June 21st also? We truly live in the future...

It's available now! Sorry for the delay.

I don't see it yet on us-west-2 (bedrock -> model access). Do you mean another region? Or does the account have to be in a special canary group?

Unfortunately still thinks "There are two 'r's in the word "raspberry"."

The only one that got it right was the basic version of Gemini "There are actually three "r"s in the word "strawberry". It's a bit tricky because the double "r" sounds like one sound, but there are still two separate letters 'r' next to each other."

The paid Gemini advanced had "There are two Rs in the word "strawberry"."

This isn't a very good question because of how tokenizers work: it can't see individual letters. If you wrote it with some separator between the letters, e.g. r - a - s - p - b - e - r - r - y, it'd probably do much better.

One theory I heard about this type of problem is because these algorithms tokenize the text early, and each token can be multiple characters.

My biggest gripe with Claude is how easily it hits the rate limit and falls down to lower quality model.

Having a rate limit in a paid subscription is lame.

Does anyone have tips on how to go about using it for refactoring an existing (larger) codebase?

So far it isn’t doing better or worse than gpt4o, if you want someone to switch, it better be way better or way better price. The price is exactly what OpenAI is charging to the cent. So no, you won’t get someone to switch because the differentiator is just the UI

No ARC-AGI benchmarks?

They said it is available on Bedrock, but it isn't :(

It's live now! Sorry for the delay.

I still get

{"message":"Could not resolve the foundation model from the provided model identifier."}

on us-west-2.

Hey cool, it's available in Sweden!

After validating my email and phone number the login failed though...

This is the third time Anthropic releases something interesting and I try to login to claude.ai and get banned by an "automatic review".

Thankfully they are not Google, if you follow the appeal instructions they actually un-ban you after a few days. Then I don't want to try it anymore.

Granted, I don't use it frequently, but so far this automatic ban is awful.

OpenAI must be cooking something huge for them to not be releasing products far ahead of competitors

Idk about that, they did that weird event pre google IO and still haven't released the features they announced.

Wouldn't be surprised if the only thing cooking is OpenAI itself.

They released the model announced in the demo but they haven't released the new way to interact with said model. I highly doubt they've got a significantly better model to release already.

I would rather they spend time on making their model smarter than cooking some gimmick to impress public or their shareholders

Why does it still lose to me at a simple game of tic tac toe, smh

This is also one of the first things I test with new models. I did notice that while it still plays very poorly, it is actually far more consistent with the board state, making only legal moves, and noticing when I win than is GPT4o.

I gave it a fairly simple coding questions and it failed pretty severely, to be fair ChatGPT 4o also failed that. Just saying it ain’t all that given the hype

Can you share the coding questions it failed on?

Has a limit, after 5 ish questions I got "You are out of free messages until 10 PM" which I have never had on chatgpt

Yes but chatGPT very quickly switches to the very outdated 3.5 model. Plus right now this is going to be peak demand as everyone tests it out.

The trial requires a signup with an email address. No thanks! This is one thing Microsoft got right with CoPilot.

With so much competition, I wonder why everyone else makes it hard to try out something.

You're welcome to use other models; as for me, I started using Claude 3 shortly after it came out and I've never felt like switching to the "competition". Their stance on safety aligns with my take on it, and they don't use user data for training purposes. Matter of fact, I just got my first customer for using AI services last night when I live-coded a demo in front of them, and that was with Opus. I'm thrilled to see what I can do with the new tech! I've been trying it out a little bit this morning but haven't seen much improvement (yet).

You made an account just to comment that? Admittedly, it's easier to make a HN account than to sign up for Claude, but still.

CoPilot is pretty damn bad though...

Phone # requirement is a bigger blocker.
