Mistral AI发布专为Lean4设计的开源模型Leanstral1.5，采用Apache-2.0许可。该模型总参数119B，仅6B激活参数，兼顾高性能与低成本。在miniF2F形式数学基准中，验证集和测试集均达100%完成率，并已挑战Putnam等高难度推理任务。
欧洲Mistral AI推出数学形式化证明模型Leanstral 1.5，专为Lean4语言，总参数119B但推理仅激活6B，以极低开销和Apache-2.0许可完全开源。在miniF2F基准上验证集和测试集均达100%完成率，PutnamBench同样表现惊人。
Kimi 技术团队近日发布了 Kimina-Prover 预览版的技术报告，并开源了1.5B 和7B 参数的模型蒸馏版本、用于数据生成的 Kimina-Autoformalizer-7B 模型以及修订过的 miniF2F 基准测试数据集。Kimina-Prover 是由 Numina 和 Kimi 团队联合研发的一款数学定理证明模型，它在形式化定理证明领域采用了一种新颖的、由推理驱动的探索范式，展现出极佳的性能。
