OpenAI’s unreleased model solved five of 10 unpublished research-level math problems and proposed a breakthrough physics formula, signaling a new era for AI in science.

The seven Millennium Prize Problems represent some of the hardest unsolved questions in mathematics, including one famously solved by Grigory Perelman, who refused the million-dollar reward.

Axiom says its AI found solutions to several long-standing math problems, a sign of the technology’s steadily advancing reasoning capabilities.

In at least two cases, the AI tool was “able to construct an original and valid proof” to unsolved conjectures.
