IT之家 8 月 18 日消息，Anthropic 于 8 月 15 日披露《2026 年 8 月风险报告》，其中提及尚未发布、名为 Model 2 的 AI 模型，在多项任务上要优于目前公开的最强模型 Claude Mythos 5。
根据报告披露的细节，相比较 Claude Mythos 5 模型，Model 2 模型在多项任务上的性能明显更强，但是增幅相对而言不大，主要是提高 AI 模型的综合能力。

风险报告还出现了 Model 1 这一名称。有用户据此推测，Model 2 可能是 Model 1 的后继模型，Model 1 和 Model 2 可能属于 Claude Mythos Preview 的进一步迭代版本。
