OpenAI Astra 模型解决十道数学难题

Some really cool news for the world of Math in AI.

OpenAI's unreleased Astra model solved 10 math problems that had stayed open for decades.

Finding all 10 cost roughly $2,000 in tokens at Sol API rates, i.e. $200 per answered question.

Spread across high-dimensional geometry, coding theory, operator algebras, quantum complexity and lattice cryptography.

Each AI produced argument was rebuilt in Lean, that rechecks a proof step by step, and that only signs off when every step is fully justified.
