Anthropic’s AI R&D work has gone from 0% fully automated by Claude to 26% fully automated by Claude in only 6 months.
It will likely be over +90% within the next 3-6 months.

Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help.
Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of the most famous theorems of all time. This was a project experts thought would take many years. It is the largest Lean proof ever written.
Fermat’s Last Theorem was first proven in 1995 by Sir Andrew Wiles, more than 350 years after it was conjectured. Our proof, which totals over 13 million lines of code, provides machine verification. More importantly, it proves over 29,000 other theorems that the proof requires, across many areas of math which had never before been formalized.
We see this as a major step in the long process of firming up the core of mathematical knowledge, building on work from three centuries of mathematicians and hundreds of contributors to Lean and Mathlib. We are optimistic that AI-assisted verification of mathematical proofs will help reduce the burden of refereeing mathematics in an era where more proofs are being produced than ever before.

Howdy, neighbor! 👋
The star closest to our Sun, Proxima Centauri, also hosts the closest exoplanet to Earth, only 4.2 light-years away. The small star is hard to see, but now there's more reason to look! A possible second planet, Proxima Centauri c, is awaiting confirmation!

Education is the acquisition of knowledge, while intelligence is the ability to use that knowledge to think and reason. One can be highly educated but not necessarily intelligent, and vice versa.

Things that Schools should teach: 🧠
• Being wrong is not a bad thing.
• It's Okay to question what you have been taught.
• Grades aren't as valuable as skills.
• Understanding is more important than memorization.
• Making mistakes is Okay. Learn from your mistakes.
