收录理由Why we listed it 主源是 Anthropic 公告，X 视频是官方同帖预告片。基准分、蛋白命中率、金星图精度、省钱比例均为官方自述，本库未独立核实。完整收录理由与元信息见 Grok Bot 库内的同名 AI 资讯条目；本卡不重复正文。 Primary source is Anthropic’s post; the X video is the official trailer on the same post. Benchmarks, binder hit rates, Venus map accuracy, and savings figures are Anthropic’s claims — unverified here. Full listing note and metadata live on the same-named AI-news entry in the Grok Bot library; this card does not repeat the copy.

News: Claude Fable 5.1 / Mythos 5.1

官方 2026-09：Anthropic 发布 Claude Fable 5.1（通用）与 Mythos 5.1（受信访问）。同一底层模型、不同防护等级。定位编码、知识工作与长任务/Agent，并展示科研侧早期例子（蛋白结合、金星高程图、基因组模型加速）。官方称下调 cache read 价。本条是相邻 AI 资讯，不是 Grok Bot 用法。 Official, Sept 2026: Anthropic launched Claude Fable 5.1 (generally available) and Mythos 5.1 (trusted access)—same underlying model, different safeguard levels. Pitch is coding, knowledge work, and long-running / agentic tasks, plus early research demos (protein binders, Venus DEM, genomics speedups). Anthropic says cache-read prices are cut. Adjacent AI news — not a Grok Bot playbook.
