OpenAI says Astra cracked 10 math problems no model could touch

OpenAI put its next model, Astra, up against a century-old math benchmark and it solved 10 problems that previous models could not. The problems are old — they've been sitting in the literature for decades, waiting for a model sharp enough to find the solution. Astra found them.

The benchmark is the kind that doesn't lie: a small set of problems with known answers, not a broad but fuzzy evaluation. That matters because it means the 10 solves are real, not a product of a lenient scoring rubric. The problems were open for a long time. Astra closed them.

Why this matters for us: when models start solving hard problems that have sat unsolved for decades, it means the tools we use — the ones that plan routes, schedule shifts, crunch numbers for the small shop — are getting sharper without anyone having to buy a new license.
