Anthropic 最强模型仍未对外发布

Why we picked it

Anthropic 内部已经有一个没对外公开的更强模型,这条消息出自 Mythos 5.2 的 System Card。关注 Claude 竞品节奏的人可以留意,等官方 System Card 出来再对比。

Andrew Curran 在 X 上发文称 Anthropic 能力最强的模型仍处于未公开状态,藏在公司内部。其信息来源为 Fable/Mythos 5.2 的 System Card。除此之外,推文未给出该模型的参数规模、基准成绩或发布时间。

Body

System Card 是模型发布时披露训练过程与安全评估的文档,以此作为信息出处说明该消息与模型内部评估材料相关。具体模型能力与上线安排仍以 Anthropic 官方发布为准。
