- Mythos 5 用不了:仅限 Glasswing 合作方 + 部分生物研究者,无公开 API ID
- 安全回退:涉网络安全/生化/蒸馏的请求自动转交 Opus 4.8 处理
- 数据保留:Mythos 级模型全流量强制 30 天留存(一/三方接口都是)
Fable 5 能,Mythos 5 不能,所以依然是羊头猪肉
好消息似乎是6/22 之前免费体验不算额度?要求Fable 5 Claude Code ≥ v2.1.170
▎ "On June 23, we'll remove Fable 5 from those plans. Using it after that will require usage credits."
▎ "After this point—when sufficient capacity allows—we aim to restore Fable 5 as a standard part of
▎ subscription plans."
Claude Fable 5 and Claude Mythos 5
Today we’re launching Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
