What Is Mistral Large 4?Mistral Large 4 是什么？
Mistral Large 4 is Mistral AI's flagship mixture-of-experts (MoE) model, released in Abu Dhabi on October 6, 2026, with an API public preview already open. It packs 1.05T total parameters with only about 49–52B activated per token — flagship-scale capability at a fraction of the dense-model inference cost — plus a 1.6B vision encoder, a 1M-token context window, and support for 160+ languages.Mistral Large 4 是 Mistral AI 2026 年 10 月 6 日在阿布扎比发布的旗舰混合专家（MoE）模型，API 公开预览已开。它有 1.05T 总参数，但每次推理仅激活约 49–52B——旗舰级能力，推理成本只是稠密模型的一小部分；另有 1.6B 视觉编码器、100 万上下文、支持 160+ 语言。
API pricing is $1.36 input / $4.18 output per million tokens; the launch half-price promotion ended on October 20, 2026. Prices are per the official site.API 定价 $1.36 输入 / $4.18 输出每百万 token；首发半价优惠已于 2026 年 10 月 20 日结束。价格以官网为准。
Mistral Large 4 is the most aggressive "efficient frontier" bet of late 2026: 1.05T total parameters with only 49–52B active is the MoE playbook pushed to flagship scale, and the 1.6B vision encoder signals that Mistral wants multimodal as a first-class citizen, not an afterthought. At $1.36/$4.18 per MTok it undercuts most flagship-tier APIs while offering a 1M context and 160+ languages — a genuinely disruptive price/performance point for long-document and multilingual workloads. The honest caveats: the weights are not released yet (as of October 23, 2026, expected end of the month, license unknown) — so the "open weights" story Mistral is famous for is a promise, not a fact, right now — and the launch half-price already ended on October 20. Verdict: as an API, it is one of the strongest value plays in the flagship tier; as an open-weights story, wait for the actual release before counting on it.
Mistral Large 4 是 2026 年底最激进的「高效前沿」赌注：1.05T 总参数、仅 49–52B 激活，是把 MoE 打法推到旗舰规模；1.6B 视觉编码器说明 Mistral 要把多模态当一等公民，而不是事后补丁。$1.36/$4.18 每百万 token 的价格低于大多数旗舰级 API，还给 100 万上下文和 160+ 语言——对长文档和多语言场景是实打实的性价比冲击。真实代价：权重还没发布（截至 2026-10-23，预计月底，许可证未知）——Mistral 赖以成名的「开放权重」故事目前是承诺不是事实；首发半价也已在 10 月 20 日结束。结论：当 API 用，它是旗舰档里性价比最强的选择之一；当开放权重故事看，等正式发布再指望它。
