Pythagoras-Prover: Advancing Efficient Formal Proving via Augmented Lean Formalisation

In three linesPythagoras-Prover is an open-source family of efficient Lean theorem provers (4B and 32B parameters, including a diffusion-based prototype). Via curriculum SFT and Augmented Lean Formalisation (ALF), the 4B model outperforms DeepSeek-Prover-V2-671B on MiniF2F-Test (86.1% vs 82.4%) with 167x fewer parameters. The 32B achieves 93.0% on MiniF2F-Test and solves 93/672 PutnamBench problems.
