tacone··on Qwen 3.8 27B available on Cerebras at 1500 tokens/s
Noticed they are present in OpenRouter, but Qwen 3.8 is not there yet. Hopefully it'll get there soon.

For those who haven't noticed though, the context size they allow for Qwen is just 128k. Still interesting as a specialized sub-agent but not really well suited for long tasks.

tacone··on Our position on open-weights models
I copy pasted this whole debate in Claude Sonnet 5 (web). The model came up with a summary but the thinking trace was entirely omitted.

Well, if you ask me, that is dangerous.

tacone··on “We have information that Moonshot distilled Fable for the development of K3”
So it is as "dangerous" as Fable?

tacone··on Ask HN: What Are You Working On? (July 2026)
Vibecoded a simple YouTube summarizer: https://github.com/tacone/prosey

The code might be slop, but it saves me time extracting information from long-form videos that would require 20-60 minutes of my time otherwise.

Also I get to not feed the algorithm just for the sake of curiosity.

tacone··on AI's Affordability Crisis
My take is that Anthropic and OpenAI simply are NOT competing on price. 2 big players are often not enough to create tension on price.

Chinese models and open model providers are, indeed, competing on price, and the difference shows.

Looks great, especially on mobile, congrats!
tacone··on Statement on US government directive to suspend access to Fable 5 and Mythos 5
That's actually a good point. I had Fable available almost immediately under my Copilot subscription and never bothered to use it even to say hello.

But from what I hear, Fable looks like an incremental update, with improved behavior imprinted by training.

Something that you could theoretically approximate by using a good set of instructions and model orchestration (tweaking the session life cycle, using a second model to understand user intentions, using a third model to prevent drift, ...).

If the above is true, the only discriminator would be user effort.

If Fable is dangerous, then we are still in danger right now, and have been for the last few months at the very least.

tacone··on Claude Fable is relentlessly proactive
I'm starting to think that what Anthropic really fears is not vulnerability discovery but rather Fable going around the internet making trouble.

tacone··on Angry devs vow to flee GitHub Copilot as metered billing takes hold
Cancelled my personal subscription (annual) yesterday.

- they "swallowed" my monthly subscription in January, I had to subscribe (and pay again)

- they promised tools to preview the new costs, they did too little and too badly (you have to click an export button, wait for a mail and click on a link on it, then download their csv which even showed substantial dollar costs for rows with 0 requests)

- models kept on appearing/disappearing/re-appearing-disabled on our company account in the latest weeks

- as of May 31th, I had no clue and could not tell if I would been migrated to token billing, or would have to stay with the moronic new multipliers. News came on Jun 1st, of course

They don't really look able or willing to properly manage their own product at the moment. And yes, new subscription are paused, so I won't be able to re-subscribe.

Quite frankly the only reason to go copilot is to have it in the VSCode chat (and yes, there's some chance to use it BYOK, provided it works).

Besides, their offering even at market prices looks inferior to what you can get elsewhere. You can use DeepSeek and pay pennies, use Fireworks and have the choice to use cheaper open models (which GitHub does not provide, and are actually good and even better than Claude sometimes), or subscribe to Open Router and use virtually anything.

I still have no idea if cancelling my subscription will get any money back, probably not.

tacone··on Creatine raise brain energy levels and slow Alzheimer's cognitive decline by 30%
Well.. I can't, nobody can. Perhaps it was a placebo effect or perhaps I had low levels of creatine and felt the difference. I often felt better right after taking it though, not consistently but often.
tacone··on Creatine raises brain energy levels and slows cognitive decline: study
The first time I took creatine (6g IIRC), I actually felt the mental effect just 2 minutes later. A pleasurable sensation of augmented presence and (mental) relaxation.

I paused taking that momentarily out of precaution while I wait some physical issue to normalize, but I plan to resume it in some weeks. Also it is considered a very safe supplement.

tacone··on Perry Compiles TypeScript directly to executables using SWC and LLVM
Just spent an hour trying to make it work (including re-compiling) with the jsruntime.

`Error: JavaScript modules found but libperry_jsruntime.a not found. Build it with: cargo build --release -p perry-jsruntime`

Turns out jsruntime was removed one week ago, but the error messages probably not have been updated as they should.

tacone··on Show HN: Promptloop – create, run, and improve prompt evals from the terminal
I don't really understand why the comment has been downvoted.

We actually need more of this, perhaps not in this exact shape, but similar.

It would be extremely cool to be able to write one or two lines of prompt in my harness, and have a light model iterate with me a few times writing/proposing requirements, guidelines and explanations, refining the prompt until it's ready to be sent to the actual LLM.

Lack of specifications in the prompt is (imho?) one of the main drivers that lead the LLMs astray, and it often happens because it's not realistic to always type or even thing every angle before submitting each prompt.

Think of it as the missing link between a single-shot prompt and a skill.

It should be ideally integrated in the chat, for quick access.

This project is probably different in aim, but I still find it interesting.

Doesn't compaction invalidate token caching, btw?

tacone··on Launch HN: Superset (YC P26) – IDE for the agents era
I am looking for something similar. Any tutorial or resource on how to set up things?
tacone··on Launch HN: Superset (YC P26) – IDE for the agents era
I was looking exactly for something like that. I tried installing the Linux version and it runs but:

1. it's behind a login wall | 2. tries to download its own OpenCode instead of using the one installed on my machine

I also tried to create a new workspace. It asked what I want to do. I tried with "create user accounts", and it proceeded to create the git worktree (without asking for its name) and sent that prompt straight to OpenCode without allowing me to choose the LLM model.

I plaud the effort - I really do - but it doesn't really seems a great experience for now.

tacone··on Zerostack – A Unix-inspired coding agent written in pure Rust
It's also dealing with memory issues (see: Memory Megathread https://github.com/anomalyco/opencode/issues/20695).

And in my experience is not that much faster to start than more complex software like Visual Studio Code.

tacone··on Why most product tours get skipped
Because most often their real purpose is to stand out in a powerpoint presentation.
tacone··on The Claude Code Source Leak: fake tools, frustration regexes, undercover mode
Also for future reference, Copilot - specifically - includes a configuration flag to toggle the co-authorship (see `copilot help config`):

> `includeCoAuthoredBy`: whether to instruct the agent to add a Co-authored-by trailer to git commits; defaults to `true`.

This means that, if you don't explicitely configure otherwise, the LLM is specifically instructed to include co-authorship in its higher level instructions.

tacone··on The Claude Code Source Leak: fake tools, frustration regexes, undercover mode
It doesn't work so well in my experience. I am currently wrapping (or asking the LLM to wrap) the commit message prompt in a script call.

   1. the LLM is instructed on how to write a commit message and never include co-authorship
   2. the LLM is asked to produce a commit message
   3. the LLM output is parsed by a script which removes co-authorship if the LLM chooses to include it nevertheless
tacone··on Apideck CLI – An AI-agent interface with much lower context consumption than MCP
Actually what it seems to tackle at its core is discoverability. Which should be built in in each MCP server as it's not that difficult, instead, we see MCP servers with 50+ methods.

Much easier:

    { action: 'help' }

    { action: 'projects.help' }

    { action: 'projects.get', payload: { id: xxxx-xx-x } }
And you get the very same discoverability.

There are other interesting capabilities though, like built in permissions based on HTTP verb, that might be useful to someone.

tacone··on Optimizing Top K in Postgres
My apologies, the article was talking about 100M-rows datasets so I presumed that was the scenario.
tacone··on Optimizing Top K in Postgres
The issue here is the row based format. You simply can't filter on arbitrary columns with that. Either use an external warehouse or a columnar plug-in like Timescale.
tacone··on Ask HN: What Are You Working On? (March 2026)
I am creating AI coding framework (a set of skills and scripts, really), since it seems a lot of them don't support copilot.

I don't think what I am doing is really original, but it's shaping nicely.

I am working on:

- feature folders (one folder per feature, with changelog, issues, summaries etc)

- coworkers (cli-agents, with session management)

- agents intra-response messaging

In general the goal is forcing Claude to behave, which is quite ambitious :).
