Mistral 发布了 Leanstral 1.5,一个面向 Lean 4 证明工程的最新开源模型,权重已上传至 Hugging Face。Lean 4 既可用作通用函数式语言(开发 CLI 工具和库),也可作为证明助手机械验证代码、协议和算法的性质。引用数据显示,Leanstral 1.5 展示了形式化推理模型中最强的 test-time scaling:在 PutnamBench 上,Pass@8 随 token budget 从 25k 提升至 4M 持续稳定增长。
ICYMI: Mistral released Leanstral 1.5, a SOTA open model for Lean 4 proof engineering.
Developers use Lean 4 as a general-purpose functional language (for CLI tools and libraries) and as a proof assistant to mechanically verify properties of code, protocols, and algorithms.
