alvis··on Dots
My only complaint to dots is that why their mascots are looking the same as grok bot
alvis··on GPT 6.1 Sol: Near-Astra intelligence for a fifth of the price
Cache is priced at $0.1/M, 50% as sol 6 and sonnet 5.5.
alvis··on Sonnet 5.5 System Card [pdf]
Unbelievable. Sonnet 5.5 max is performing better than opus 5.5
alvis··on Claude Opus 5.5
60% cache read is cool, but subscription only get 25% more according to Cat. I'm confused
alvis··on Claude Opus 5.5
$0.20 vs the old $0.5 cache read is pretty much 60% off
alvis··on OpenAI begins rolling out GPT-6 Astra
"Once it is available in the API, Astra will cost $10 per million input tokens and $50 per million output tokens. That is 2.5 times Sol’s current promotional price, although it matches Anthropic’s pricing for Fable 5.1."

Open AI finally find an edge to stop selling cheap and earn from the high demand customer like Anthropic

alvis··on Advancing the price-performance frontier with GPT‑5.6
Basically lunar at extra level can cover all use cases scenarios other than those requiring opus up. Goodbye sonnet and haiku
alvis··on Ask HN: How to rewrite `Claude.md` and install the skill for Opus5 and Fable5
These models don't take claude.md, Claude Code does, and claude.md still get fed to these models if you're using Claude Code.

That said, prompting on opus 5 needs new technique: https://platform.claude.com/docs/en/build-with-claude/prompt...

alvis··on Claude Opus 5
Also the cost per task. It appears to be significantly cheaper, cheaper than sonnet!
alvis··on Claude Opus 5
What really impress me is opus 5 is better in alignment than fable 5!

here we go
alvis··on 5 Hour Limit on Codex removed, reset within next hour
It was almost from no more access to frontier models to having too much access in the past hours
alvis··on Claude Code May–July 2026 weekly limits promotion
Who would expect fable will really get removed given the competition?

But 50% more limit is completely unexpected to me

alvis··on Claude Code May–July 2026 weekly limits promotion
I'd say 5.6 Sol performs between opus and fable, but not yet fable.

Just that given its cost efficiency, claude subscription isn't attractive at all when fable is removed.

alvis··on Claude Sonnet 5
Ironically, the key message of today's release is that Sonnet 5 is far less capable than Opus 4.8 and Mythos 5. It's a funny development is the past few weeks
alvis··on Claude Sonnet 5
What I starting to hate is that each model's effort level can mean completely different power.

Today sonnet 5's med level effort is equivalent to sonnet 4.6 low level effort :/

alvis··on Claude Fable 5
Another thing to note: 30-day retention for all traffic on Mythos-class models

Is it good or bad? 30 days is a long time for anything bad to happen

alvis··on Claude Fable 5
It’s too obvious that antropic need to find way to earn enough revenue before IPO. Claude subscription isn’t earning earning much money I bet
alvis··on Meta confirms 1000s of Instagram accounts were hacked by abusing its AI chatbot
how on earth a password reset API would take both email address and account id as parameters? The chat bot is fine. I bet it's the API written by AI the issue
alvis··on Five frontier LLMs disagree on 67% of 1k real-world fact-check claims
The problem is that it's testing claims (or some people would prefer calling them "truths") without much context.

Take just one random example: `Hostels in Kota, Rajasthan commonly use caged ceiling fans as a preventive measure against student suicides`

While `Hostels in Kota, Rajasthan commonly use caged ceiling fans` may be a verifiable facts (though I doubt if there are any statistics for verification but let's say there are), `a preventive measure against student suicides` is a claim that no one can prove that. It can just a believe at most.

Arh. Did Biden stole Thump 2nd term? Truth or fact or claim?

alvis··on SpaceX says it has agreement to acquire Cursor for $60B
Who are the users? I haven't seen many pro users using cursor
alvis··on SpaceX says it has agreement to acquire Cursor for $60B
can't X recreate one with 1B? As an IDE, honestly I can't even understand it needs more than 1M to create
alvis··on Stop trying to engineer your way out of listening to people
This also apply to talking to your wife too.
alvis··on Ask HN: How to solve the cold start problem for a two-sided marketplace?
yeah. I have the same pain. But for your case, don’t start as a marketplace. Start as a concierge service on one route, one parcel category, and one trust model. If you can’t force the first 20 successful matches manually, the market is still too under-specified. my 2cents
alvis··on Claude Opus 4.7
I don't have much quality drop from 4.6. But I also notice that I use codex more often these days than claude code
alvis··on Claude Opus 4.7
TL;DR; iPhone is getting better every year

The surprise: agentic search is significantly weaker somehow hmm...

alvis··on OpenAI closes funding round at an $852B valuation
With $122B what are you going to build next? Spaceships?
alvis··on ManusAI Joins Meta
A random thought. Metaverse is more interesting if manus get integrated into it
alvis··on Claude Opus 4.5
“For Max and Team Premium users, we’ve increased overall usage limits, meaning you’ll have roughly the same number of Opus tokens as you previously had with Sonnet.” — seems like anthropic has finally listened!
