DeepSeek-AI Open-Sources DeepSeek-Prover-V1.5: A Language Model with 7 Billion Parameters that Outperforms all Open-Source Models in Formal Theorem Proving in Lean 4

DeepSeek-Prover-V1.5 is an advanced tool that helps in proving theorems in a formal and organized way. It addresses the challenges faced by large language models in mathematical reasoning and theorem proving using systems like Lean and Isabelle. Practical Solutions and Value: - Enhanced base model with further training on mathematics and code data - Improved Lean 4 code completion dataset through data augmentation techniques - Utilized reinforcement learning from proof assistant feedback and advanced tree search methods Significant Advancements: - DeepSeek-Prover-V1.5-RL achieved a 60.2% pass rate in whole-proof generation, a 10.2 percentage point improvement over its predecessor - On the miniF2F-test dataset, it proved 51.6% of problems with a limited sampling budget of 128 attempts, outperforming other methods - Achieved a state-of-the-art 62.7% pass rate with RMaxTS tree search - Outperformed existing methods on the ProofNet dataset, demonstrating superior performance across different theorem-proving tasks and methodologies. Key Features: - 7 billion parameter language model - Specialized pre-training, supervised fine-tuning, and reinforcement learning via GRPO - Incorporates RMaxTS, an innovative Monte-Carlo tree search variant Future Developments: - Future developments may include a critic model for assessing incomplete proofs, addressing the exploitation aspect of reinforcement learning in theorem proving.
