Deepseek Prover V1.5 RL
DeepSeek develops Deepseek Prover V 1.5 RL, an open-source language model optimized for theorem proving in Lean 4. It is genuinely best at formal mathematical languages, achieving state-of-the-art results on the miniF2F and ProofNet benchmarks, with a top score of 63.5% on the miniF2F-test set. Notably, the model employs a variant of Monte-Carlo tree search called RMaxTS, which utilizes an intrinsic-reward-driven exploration strategy to generate diverse proof paths, and has 7B parameters.
