Mistral 開放萬億參數旗艦 Large 4 權重，改採修改版 MIT 授權，僅 MaaS 轉售須另談授權Mistral opens the weights of its trillion-parameter Large 4 flagship under a modified MIT licence, requiring a separate deal only for hosted resale
- 事件
- 法國 Mistral 於十月二十九日開放 Mistral Large 4 權重。模型總參數一萬億、每 token 激活四百九十億，原生多模態，用歐洲自有數據中心三千八百塊 Grace Blackwell 訓練。France's Mistral released the weights of Mistral Large 4 on 29 October. The natively multimodal model carries one trillion total parameters with 49 billion active per token, trained on 3,800 Grace Blackwell GPUs in its own European data centres.
- 背後
- 模型自十月六日預覽後追加三週強化學習，主攻編碼與防禦性網安。開源陣營要證明前沿能力不必綁定單一供應商。Three further weeks of reinforcement learning since the 6 October preview targeted coding and defensive cybersecurity. Open weights must show frontier capability need not be tied to one vendor, which resonates most in sectors that must demonstrate control.
顧問觀點
我們認為開放權重的真正賣點是不會被切斷的存取權，而非跑分。企業應把它當作談判籌碼：保留一條自託管路線，即使短期不用，也能壓低閉源方案的漲價空間。We see the real selling point of open weights as access that cannot be cut off, not leaderboard position. Treat it as negotiating leverage: keep a self-hosted route on file and it caps the pricing power of closed vendors even if unused.
- 對日常工作的影響
- 資訊主管要把運行門檻算清：FP8 要八張 B300、壓縮版要四張 GB300，硬件與運維成本須與 API 報價同表比較，否則自託管的帳面優勢會在第二年消失。IT leads must price the floor: FP8 needs eight B300 GPUs and the compressed build four GB300s. Put hardware and operations in the same table as API rates or the apparent saving disappears in year two.
- 如何改善
- 本週挑一個已經上線、對外可斷的工序，試算自託管與 API 兩條路線的年成本，寫成半頁備忘給財務。This week, take one live workflow that can be cut off externally, cost the self-hosted and API routes over a year, and send finance a half-page memo.
