美國商務部6月30日解除對Anthropic Claude Fable5及Mythos5模型的出口管制，7月1日全面恢復訪問。此前因亞馬遜研究員發現Fable5存在可被誘導提供網絡攻擊信息的漏洞，商務部於6月12日緊急限制該模型訪問權限，禁令波及Anthropic外籍員工，導致模型下線近三週。
智譜計劃8月發佈新一代基座大模型GLM-5.5，參數量有望破萬億，實現架構重大跨越。此舉正值美國限制Anthropic旗下Fable5與Mythos5模型訪問，這兩款模型長期盤踞全球榜首。國際大模型格局變動下，智譜藉此機遇加速突破，或填補市場空白。
Anthropic發佈Claude5系列，含面向大衆的Fable5與側重安全的Mythos5。Fable5是公開市場最強模型，在軟件開發、科研分析、視覺識別等領域表現優異，相比前代Opus在長週期任務中處理能力顯著提升，同時體現了企業在模型應用邊界與安全架構上的深思熟慮。
Anthropic發佈第五代Claude系列兩款模型：通用型Claude Fable5和專業型Claude Mythos5。兩者基於相同基礎模型，但安全配置和應用場景不同。Fable5在主流測試基準中表現優異，尤其在長時間複雜任務處理上展現出碾壓級能力，編程與通用知識領域成績突出。
