阅读原文· mistral.aiMistral AI 于2025年3月17日发布 Mistral Small 3.1。该模型在 Mistral Small 3 基础上改进，支持最高 128k tokens 上下文窗口，推理速度达 150 tokens/秒，并支持多模态理解。官方称其性能超越了 Gemma 3 和 GPT-4o Mini 等同量级模型。Mistral Small 3.1 以 Apache 2.0 许可开源，基础模型与指令微调模型均已发布。模型轻量化，可在单张 RTX 4090 或配备 32GB RAM 的 Mac 上运行，适用于对话助手、函数调用、专业领域微调及构建推理模型等多种场景。
Today we announce Mistral Small 3.1: the best model in its weight class.
Building on Mistral Small 3 , this new model comes with improved text performance, multimodal understanding, and an expanded context window of up to 128k tokens. The model outperforms comparable models like Gemma 3 and GPT-4o Mini, while delivering inference speeds of 150 tokens per second.
Mistral Small 3.1 is released under an Apache 2.0 license.
Modern AI applications demand a blend of capabilities—handling text, understanding multimodal inputs, supporting multiple languages, and managing long contexts—with low latency and cost efficiency. As shown below, Mistral Small 3.1 is the first open source model that not only meets, but in fact surpasses, the performance of leading small proprietary models across all these dimensions.
