arXiv:2606.12594v1 Announce Type: new Abstract: Modern Lean theorem provers achieve strong performance only with substantial training and inference compute, driven in part by scarce verified proof data and the long reasoning traces of formal proof search, making both supervised fine-tuning (SFT) and sampling expensive. We introduce Pythagoras-Prover, a compute-efficient open-source family of Lean theorem provers built for practical compute budgets. The family spans two generation paradigms: autoregressive models at 4B and 32B parameters, and a first proof-of-concept diffusion-based prover (4B)
The increasing computational demands and cost of current AI models for formal theorem proving necessitate more efficient solutions, especially as AI integration into complex reasoning tasks accelerates.
This development addresses a critical bottleneck in the practical application and scaling of AI in formal verification, which is crucial for software reliability, mathematical discovery, and even chip design.
The introduction of compute-efficient, open-source theorem provers makes advanced formal verification more accessible and cost-effective, potentially democratizing the development of provably correct systems.
