OpenAI’s unreleased Astra model reportedly solves ten major open math problems
TheZvi · x · 2026-08-04
A post about OpenAI’s unreleased model Astra says it solved ten major open mathematics problems and then formalized the arguments in Lean.
- The author says math is getting easier for LLMs and that Astra appears to be a real step forward.
- OpenAI is reported to have produced new results for ten problems using an internal version of Astra, with human help turning the arguments into manuscripts.
- The model then formalized each argument as a Lean certificate, suggesting a serious jump in theorem-proving capability.
