Intern-S2 Helps Resolve Ghys's Conjecture in Complex Dimension Three
A 30-year-old conjecture falling to a Chinese lab's model plus Lean verification shows AI moving from coding benchmarks into formal mathematics, where every step is machine-checked. Researchers in theorem proving and anyone tracking Chinese labs' frontier ambitions should follow the write-up. It also gives Lean-based formalisation workflows a high-profile proof point against informal LLM math claims.
Mathematicians working with Shanghai AI Lab's Intern-S2 resolved Ghys's conjecture in complex dimension three, a problem open for over 30 years. All four main theorems in the proof have been formalised and verified in Lean. The result pairs the model with human mathematicians on a long-standing open problem rather than a benchmark-only evaluation.
