Dirac, Boundless Intuition lab's prover produced machine-checked formal proofs for all six problems from this year's IMO.

The proofs were generated in Lean and checked by the Lean kernel, so the result isn't based on comparing generated answers with expected solutions: the underlying proofs themselves are mechanically verified.

The article includes the formalizations, proof traces, Timings, and links to the complete proofs as benchmarks.
