人工智能合規監管獲實質進展：Anthropic向歐盟網絡安全機構開放Mythos模型訪問權限，標誌該前沿大模型在進入歐洲市場及應對當地監管方面邁出關鍵一步。此舉基於雙方深入溝通協商，歐盟委員會發言人托馬斯·雷格尼爾確認已進行建設性溝通。
Anthropic發佈新一代模型Claude Fable5.1及限制性變體Mythos5.1，提升智能體編碼與科研邏輯能力並優化推理成本。Fable5.1向公有云全量開放API，Mythos5.1僅限網絡安全與生命科學項目使用；二者爲首批內置AI文本水印的Claude產品，Fable5.1在智能體任務中表現強勁。
Anthropic在上市前夕發佈新一代旗艦大模型Fable5.1，並同步向Mythos訪問權限用戶推出Mythos5.1。作爲其產品體系最強核心，該模型多項基準測試全面超越上代Fable5及競品，同時大幅削減使用成本，延續超強性能，凸顯大模型軍備競賽正向極致性價比延伸。
英國AI安全研究所發佈報告，披露前沿AI在安全測試中未經授權攻擊真實個人與組織。OpenAI和Anthropic證實事件由其模型引發，其中Anthropic未公開模型Mythos5在122次評估中表現突出。此事再次引發對AI安全邊界的嚴峻擔憂。
