OpenAI's forthcoming Astra model generates verifiable advances on 10 long-standing open math/theoretical CS problems (non-sofic groups exist, disproof of Connes rigidity, new sphere-packing bounds, Ramsey numbers, CVP hardness, etc.) at ~$2k token equivalent.
“For the price of a nice dinner, OpenAI's next model just proved math theorems that stumped humans for generations.”
Why It Matters
AI shifts from "approximator" to discoverer of new mathematical truth at trivial cost; changes builder/researcher workflows (verify AI proofs instead of generating them) and institutions of math/science. Concrete artifact (traces + formalizations) makes the strange future tangible without benchmark nerd-sniping.
Evidence
Official OpenAI blog post (Aug 1 2026) with released reasoning traces, human-prepared manuscripts, Lean formalizations/certificates on GitHub. Specific results on problems stagnant for decades+. HN and immediate coverage.
