OpenAI announced its next major model family, Astra, on August 2, 2026. The AI successfully solved 10 long-standing open problems in mathematics and theoretical computer science [1][3]. These solutions included machine-checkable Lean 4 certificates to ensure accuracy in fields such as group theory [1].
One major breakthrough involved the construction of non-sofic groups. This specific problem remained open for nearly three decades [1][2]. The Astra model provides formal proofs that researchers can verify using computerized theorem-proving software [1].
