OpenAI称下一代模型Astra产生10项数学与理论计算机科学新结果

OpenAI says an internal version of its next major model, called Astra, has produced ten new results in mathematics and theoretical computer science. Each of the problems had been open for at least a decade. The company published a 249-page manuscript alongside machine-checkable Lean 4 certificates for every result on GitHub. The headline result is the first-ever explicit construction of a non-sofic group, resolving a central question in group theory that has stood since Mikhail Gromov introduced the concept of soficity in 1999. No mathematician had managed to prove or disprove whether non-sofic groups exist in the 27 years since. [...] OpenAI’s head of mathematics research, Sebastien Bubeck, confirmed the results on X, calling them “beautiful” and noting that each ships with a Lean certificate and a chain-of-thought walkthrough. The total compute cost for all ten solutions was roughly $2,000 at Sol API rates, according to OpenAI. The announcement lands against a backdrop of escalatin

Non-sofic groups exist A group is sofic if finite pieces of its multiplication table can be approximated (in a precise sense) by permutations of finite sets. This notion, introduced by Gromov around 1999 (with the name coined by Weiss), generalizes both amenable and residually finite groups. Gromov asked whether every countable discrete group is sofic. The question remained open for ~27 years. > yes, nonsofic groups exist: this statement is one of many new beautiful results proved by Astra, our next major model. > > We're releasing 10 such Astra proofs, complete with lean certificates and CoT walkthroughs for each of them.

Dr Singularity / @dr\_singularity: What insane times we live in. I said a few days ago that the math Singularity is here. Now we have even more proof that it's really happening. OpenAI's upcoming Astra model family cracked 10 major unsolved problems across mathematics, quantum complexity, and theoretical computer science. Dean W. Ball / @deanwball: Everyone in the world will soon be able to use the model that made these breakthroughs for every problem they face in life, no matter how mundane, at a cost that will fall dramatically in a matter of months. I still struggle to get my head around this fact. Tibo / @thsottiaux: The week was for efficiency. The weekend is for 10 major breakthroughs in science. There will be signs. [...] Sebastien Bubeck / @sebastienbubeck: yes, nonsofic groups exist: this statement is one of many new beautiful results proved by Astra, our next major model. … Derya Unutmaz / @deryatr\_: Another major historical milestone in the age of AI has been a

Proof: I took a convex optimization paper with a clean open problem in it and asked gpt-5-pro to work on it. It proved a better bound than what is in the paper, and I checked the proof it's correct.
