We had a team of agents rebuild SQLite from its 835-page manual.
It created a replica in Rust which passed 100% of a held-out test suite.
Interestingly, cost varied 15x depending on which model mix we used.
What actually happens inside an LLM? Tokens become vectors, embeddings store meaning, matrices transform information, attention mixes context, and logits choose the next token.
We're open sourcing a 9B model that extracts structured data from documents at near-frontier performance.
- 90.2% on our bench, vs Gemini 3.5 Flash at 91.3%
- Leads extraction models like NuExtract3 (81.5%)
- 9.5s p50 timings
- Pass JSON schema
This is the magic I've been waiting for, what AI can do:
"There is the video of a squirrel somewhere in the folder, convert it to mp4"
Anthropic did it. CUA will finally become useful - this is a historic moment.
Simple RL is all you need for Small LMs
This paper shows that a single simple RL recipe can push 1.5B models to SoTA reasoning with half the compute
Suggesting whether today’s complex RL pipelines are solving real problems or ones we created ourselves..

GPT-5, Claude, Kimi, and Gemini: "I can travel back in time to any time before 1500 and change only one thing, what is the single thing you would change, nothing obvious."
Can AI help understand how the brain learns to see the world?
Our latest study, led by @JRaugel from FAIR at @AIatMeta and @ENS_ULM, is now out!

🧵 A thread:
congratulations to the FAIR team on this impressive win!
brain modeling is a key step in understanding biological intelligence, and will pave the way to our sci-fi future (brain computer interfaces, etc) 🧠
Claude now has a 1M+ context window!
@AnthropicAI absolutely cooked with the subagent release!
@rasmic was right when saying to bet on the model provider building their own tooling
Combined everything I've learned from
@elie2222@iannuttall@EyalToledano to build a beast!
We've launched Claude for Financial Services.
Claude now integrates with leading data platforms and industry providers for real-time access to comprehensive financial information, verified across internal and industry sources.
