Anthropic 发布 Claude Fable 5.2 与 Mythos 5.2 两款新模型
Anthropic 一次发了 Fable 5.2 和 Mythos 5.2 两个模型，主打高难度技术任务。有研究人员用它解出两道理论物理难题，还能和 Opus 5.5 搭配当策略参谋。搞科研或复杂工程的人可以试试看推理能力提升有多少。
Anthropic 发布 Claude Fable 5.2 和 Claude Mythos 5.2 两款模型，定位为处理高难度技术挑战的协作型模型，在编码、推理和视觉等能力上有明显提升。
据 Anthropic 官员 Mike Krieger 介绍，Fable 5.2 在复杂问题上能体现额外的智能水平，研究人员使用 Fable 5.2 解决了两道理论物理问题；他本人还将 Fable 与 Opus 5.5 搭配使用，让 Fable 充当策略层面的思考伙伴。
这两款模型面向需要长程技术攻关的用户，与前代及 Opus 系列形成互补的组合：需要推理深度时用 Fable 5.2，日常任务可搭配 Opus 5.5。对从事科研、工程和复杂项目开发的团队来说，多了一组可选的模型搭配方案。
Claude Fable 5.2 and Mythos 5.2 are out today! They’re super sharp to work with. On complex problems you can really feel the extra intelligence; researchers working with Fable 5.2 solved two problems from theoretical physics. Fable is also a great thought partner on strategy, paired with Opus 5.5 for a lot of my work. Can't wait to see how you use Fable 5.2 to bring your big ideas to life!
