AI Math Capabilities Will Keep Climbing Thanks to Lean Verification

PatrickKidger · x · 2026-08-03

The author points out that AI models will continue to improve in mathematics. This is because math allows for cheap ground-truth verification computationally via formal languages like Lean, enabling continuous hill-climbing in model capabilities.

However, this introduces a new challenge: eventually, only another highly intelligent model will be capable of understanding and telling the difference in the complex proofs generated by AI.
