Anthropic 员工宣布 Claude Fable 5.2 今日可用，输出速度比 Fable 5.1 快最多 30%，并同系列提及 Claude Mythos 5.2 在编码、推理和视觉方面的改进。作者建议多数编码和知识任务仍首选 Opus 5.5，Fable 5.2 适合最具野心的开放式技术工作，已在 Claude Platform 所有付费计划和主要云平台开放。
Claude Fable 5.2 is available today! It generates output up to 30% faster than Fable 5.1.
Fable is best for the most ambitious, open-ended technical work. I'd still start most work on Opus 5.5. It's our strongest daily driver and what we recommend for most coding and knowledge tasks.
Fable 5.2 is available on all paid plans on the Claude Platform and on all major cloud platforms. If you try it, I'd love to hear how it went. The cases where it didn't help are useful for us to hear about too.
