Claude Fable 5.2 上线 OpenRouter:1M 上下文,$8/M 输入定价

Why we picked it

Anthropic 新旗舰 Fable 5.2 上 OpenRouter 了,1M 上下文还比上一代便宜,输出快 30%。做长文档处理或大型代码库开发的可以看下这三个基准分再决定要不要换。

Anthropic 的 Claude Fable 5.2 已在 OpenRouter 上线,支持 1M token 上下文窗口,定价为每百万 token 输入 $8、输出 $40,相比 Fable 5.1 价格更低。官方称该模型定位为面向高难度技术工作的旗舰,在多数评测中表现超过 Opus 5.5。

性能方面,Fable 5.2 的输出速度比 Fable 5.1 最快提升 30%。Anthropic 公布的基准成绩包括:FrontierSWE v2 得分 69.9%,OSWorld 2.1 得分 89.3%,Humanity's Last Exam(带工具)得分 74.2%。

通过 OpenRouter 接入意味着开发者可以用统一的 API 同时调用该模型与其他厂商的模型,便于按任务切换和比价。对处理长文档、大型代码库的团队来说,1M 上下文加上低于前代的输出价格,直接改变了单次调用的成本结构。
