Anthropic發佈新一代大模型Claude Sonnet5，定位日常高頻工作流主力，主打卓越編碼、工具調用與邏輯規劃能力，性能指標逼近旗艦Opus4，再次刷新AI模型迭代速度。
Anthropic發佈新一代AI模型Claude Fable5，作爲最強大衆版，在生物學、網絡安全等領域潛力巨大。但實際使用中，它表現出“選擇性失憶”：面對高中基礎生物學問題也拒絕回答，並轉接給前代Claude Opus4.8。這並非能力不足，而是Anthropic出於極高安全標準所致。
Notion 官方宣佈已全面恢復對Anthropic旗下Claude系列AI模型的訪問權限。此前因Opus4.7和4.8模型性能下降，導致用戶請求失敗率攀升，Notion曾緊急禁用所有Anthropic模型。經過約12小時修復底層基礎設施故障，集成服務現已恢復正常。
AI初創公司MiniMax發佈旗艦大模型M3，性能驚豔：在接近真實軟件工程場景的測試中取得59%成績，超越GPT-5.5，逼近Opus4.7，具備百萬級上下文處理能力和原生多模態特性，但發佈後引發爭議。
