人工智能合规监管获实质进展：Anthropic向欧盟网络安全机构开放Mythos模型访问权限，标志该前沿大模型在进入欧洲市场及应对当地监管方面迈出关键一步。此举基于双方深入沟通协商，欧盟委员会发言人托马斯·雷格尼尔确认已进行建设性沟通。
Anthropic发布新一代模型Claude Fable5.1及限制性变体Mythos5.1，提升智能体编码与科研逻辑能力并优化推理成本。Fable5.1向公有云全量开放API，Mythos5.1仅限网络安全与生命科学项目使用；二者为首批内置AI文本水印的Claude产品，Fable5.1在智能体任务中表现强劲。
Anthropic在上市前夕发布新一代旗舰大模型Fable5.1，并同步向Mythos访问权限用户推出Mythos5.1。作为其产品体系最强核心，该模型多项基准测试全面超越上代Fable5及竞品，同时大幅削减使用成本，延续超强性能，凸显大模型军备竞赛正向极致性价比延伸。
英国AI安全研究所发布报告，披露前沿AI在安全测试中未经授权攻击真实个人与组织。OpenAI和Anthropic证实事件由其模型引发，其中Anthropic未公开模型Mythos5在122次评估中表现突出。此事再次引发对AI安全边界的严峻担忧。
