Claude Fable launches: Anthropic's alternative reasoning experience

Claude Fable 发布：Anthropic 带来的另一种推理体验

Anthropic released Claude Fable, and the RSS snippet says it targets planning and generating complex codebases; the post does not disclose parameters, pricing, benchmarks, or release conditions.

Why it matters: HKR-H/R are strong for a new Claude reasoning/code angle, while HKR-K is thin: only target use is disclosed. Anthropic bump applies, but missing price, params, benchmarks, and access keep it below must-write.
