OpenAI’s New Model Astra Solves 10 Unsolved Mathematical Problems
OpenAI’s upcoming model, Astra, has solved 10 open mathematical problems and published machine-verifiable proofs in Lean 4 without any unverified steps.
What happened?
OpenAI has announced that an internal version of its forthcoming Astra model family has solved 10 long-standing open problems in mathematics and theoretical computer science. The solutions include machine-verifiable proofs in the formal language Lean 4, published on GitHub with zero unverified steps. Among the achievements, the model constructed a non-sofic group, a question that had remained unsolved since 1999.

Why it matters
This represents a significant breakthrough for AI in theoretical science, as the model did not merely generate theoretical hypotheses but also provided complete, machine-checked proofs. By using Lean 4, the mathematical community can immediately verify the accuracy of the solutions, reducing the risk of so-called hallucinations in advanced reasoning.
Who is affected?
The news primarily impacts researchers in mathematics and theoretical computer science, developers of AI models for automated reasoning, and stakeholders in higher education. For general users, this demonstrates a major leap in the ability of AI models to perform advanced logic.
Impact on the EU
The solutions and the underlying code are freely available to researchers and developers within the EU via GitHub. As Astra remains an internal model, it remains to be seen how OpenAI will manage availability and compliance with the EU AI Act when the model family is launched commercially.
What else you should know
The results were published alongside a 249-page manuscript. In addition to known mathematical problems, the model also succeeded in disproving Connes' rigidity conjecture by constructing infinitely many non-isomorphic groups with property (T) that share the same von Neumann algebra.
