OpenAI’s Astra solves 10 long-open math problems and publishes the proofs
OpenAI's Astra didn't just solve 10 long-open math problems—it published machine-checkable proofs. That's a capability inflection.
Why it matters
Astra demonstrates a frontier leap in reasoning and formal verification: solving decade-old problems in mathematics and theoretical CS with publishable proofs signals a qualitative shift in model capability that reshapes how practitioners think about AI for research and verification tasks.
