AWS在re:Invent2025大會上推出四款自研“Nova2”系列大模型，覆蓋文本、圖像、視頻、語音多模態場景，並首次內置網頁檢索與代碼執行能力，宣稱在價格性能比上達到業界領先。其中，Nova2 Lite定位高性價比推理，在多項基準測試中表現優於Claude Haiku4.5和GPT-5Mini，成本僅爲後者約50%；Nova2 Pro則面向複雜Agent任務。
Anthropic與微軟深化合作，三款Claude模型（Sonnet4.5、Haiku4.5、Opus4.1）正式登陸Microsoft Foundry平臺並開放公測。Azure客戶現可通過該平臺調用先進AI模型開發企業級應用與智能代理，充分融合微軟生態優勢。核心價值在於企業能在熟悉的微軟環境中便捷部署Claude系列模型。
Anthropic發佈小型AI模型Claude Haiku4.5，以低成本實現接近前沿性能，專爲實時低延遲任務設計，如聊天助手和客戶服務。Claude系列含Haiku、Sonnet、Opus三種尺寸，大模型雖知識廣但速度慢成本高，Haiku通過“蒸餾”技術平衡效率與性能。
