最近，法国人工智能初创公司 Mistral AI 宣布了他们的新一代语言模型 ——Ministral3B 和 Ministral8B。
这两款新模型是 “Ministraux” 系列的一部分，专为边缘设备和边缘计算场景而设计，支持高达128，000个 token 的上下文长度。这意味着这些模型不仅处理能力强大，而且可以在数据隐私和本地处理尤为重要的情况下使用。
Mistral 表示，Ministraux 系列模型非常适合于一系列应用，例如本地翻译、离线智能助手、数据分析以及自主机器人技术。为了进一步提升效率，Ministraux 模型还可以与更大的语言模型（比如 Mistral Large）结合使用，作为多步骤工作流中的有效中介。
在性能上，Mistral 提供的基准测试显示，Ministral3B 和8B 在多个类别中都超过了许多同类模型，比如谷歌的 Gemma 2 2B 和 Meta 的 Llama3.1 8B。值得一提的是，尽管 Ministral3B 的参数数量较少，但在某些测试中，它的表现超越了其前身 Mistral 7B。
实际上，Mistral 8B 在所有测试中都表现优异，尤其是在知识、常识、功能调用和多语言能力等方面。
关于定价，Ministral AI 的这两款新模型已经可以通过 API 获取。Ministral 8B 的费用为每百万个 token0.10美元，而 Ministral 3B 则是0.04美元。此外，Mistral 还为研究用途提供了 Ministral 8B Instruct 的模型权重。值得注意的是，Mistral 的这两款新模型很快也会通过谷歌 Vertex 和 AWS 等云合作伙伴上线。
mistralai/Ministral-8B-Instruct-2410
我们为本地智能、设备计算和边缘用例引入了两种新的先进模型。 我们称之为 Ministraux： Ministral 3B 和 Ministral 8B。 Ministral-8B-Instruct-2410 语言模型是根据 Mistral Research License 发布的微调模型，其性能明显优于现有的同类模型。 如果您有兴趣在商业上使用 Ministral-3B 或 Ministral-8B，并使其性能优于 Mistral-7B，请联系我们。 有关 Ministraux 的更多详情，请参阅我们的发布博文。
Ministral 8B 主要特点
- 根据 Mistral 研究许可证发布，如需商业许可证，请联系我们
- 使用 128k 上下文窗口和交错滑动窗口注意力进行训练
- 在大量多语言和代码数据上进行训练
- 支持函数调用 词汇量为 131k，使用 V3-Tekken 标记化器

密码检测
在本示例中，密钥信息有超过 10 万个标记，而 mistral-inference 没有分块预填充机制。 因此，运行下面的示例需要大量 GPU 内存（80 GB）。 如果想获得更节省内存的解决方案，我们建议使用 vLLM。
