Mistral Large 4 權重可供部署:控制權與授權範圍
Large 4 提供可下載權重。部署控制權擴大,但硬體、獨立測試與附條件授權仍決定實際使用範圍。

Mistral 於 10 月 6 日公布 Large 4 預覽 API,預告月底開放權重。1 Hugging Face 於 10 月 29 日介紹權重已可取得。2 開發者模型庫現已列出可下載檔案、部署說明與授權條款。3

模型規模不等於每次執行的成本
開發者模型文件說明,Large 4 採用混合專家架構,參數總量約一兆,每個詞元實際啟用約 490 億個參數;若計入嵌入層與輸出層,啟用參數約為 520 億。模型接收文字和圖像、輸出文字,標稱上下文長度為 100 萬個詞元。官方提供 FP8 及另一個 NVFP4 檢查點;後者面向 Blackwell GPU,開發者稱可減少顯示記憶體需求。3
這些是模型設計與支援能力的說明,不意味每個組織都能以低成本處理完整長度的上下文。部署所需硬體、顯示記憶體、吞吐量與實際費用,仍取決於權重量化版本與執行設定。總參數、每個詞元啟用的參數,以及上下文容量,回答的是不同問題,不能將其中一個數字當作完整的服務成本指標。
自行部署也帶來治理責任
公開權重改變的是控制範圍:企業可在授權允許的範圍內,於自有或選定環境執行模型,並對資料流、模型設定與可用性做更多安排。更大的自主性,也將存取管理、紀錄、模型更新與濫用防護責任交給部署者。
模型文件提供程式設計等基準測試結果,並介紹網路安全能力。這些是開發者公布的表現,並非本站獨立重現;基準成績不等於任何正式運作環境中的發現率、修復品質或安全保證。3 決策前仍須以實際任務測試,分清楚模型是否給出可用答案、系統是否正確執行,以及錯誤能否被發現並限制。
開放權重仍受具體授權條款約束
模型與相關文件採用 Mistral Ecosystem Open-Weight License。這是附加條件的修改版 MIT 授權,不能簡寫成無條件的 MIT 或 Apache 開源授權。條款允許相應的使用、複製、修改與部署,同時要求在副本或實質部分中保留著作權及授權通知。4
若授權使用者或其關聯方經營條款所定義的「模型即服務」業務,除第三條規定的例外之外,將模型或其衍生作品用於任何商業目的之前,須另行取得 Mistral 商業授權。條款定義聚焦於第三方能對輸入、參數或訓練資料行使實質控制的模型存取;只在特定功能中嵌入模型的終端產品,以及單純轉送其他託管模型請求的服務,不在該定義內,內部使用與透過 Mistral 官方產品存取則另有例外。不能將這概括成所有託管或所有商業使用,一律受到同一種限制。4
這次發布對希望自行部署大型模型的機構具有實際意義;採購或上線判斷仍須核對授權條款、硬體預算、獨立測試與安全治理,而不能只憑參數規模或排行榜下結論。本文對模型文件進行了編輯整理與翻譯,並保留其署名通知:2026 - Mistral;完整原始授權通知。這不表示 Mistral 為本文背書。
