Microsoft's Bubeck Teases 'Astra' Model: Solves 10 Major Math Problems with Lean Proofs
SebastienBubeck · x · 2026-08-01
Microsoft researcher Sébastien Bubeck revealed that their next major model, codenamed "Astra," has achieved significant breakthroughs in mathematical reasoning, including proving the existence of non-sofic groups.
The team is releasing 10 new mathematical proofs generated by Astra, complete with Lean certificates and Chain-of-Thought (CoT) walkthroughs. The results span a wide range of fields, from von Neumann algebras (disproving Connes' Rigidity Conjecture) to better bounds for high-dimensional sphere packing, circuit complexity, and monochromatic triangles in multicolored graphs.
