## AI 摘要

Anthropic 今日发布 Mythos 的公开版本，代号“Fable”。其成本约为 Opus 的两倍，低于此前预览版 5 倍 Opus 的定价。Fable 配备严格安全限制，在网络安全方面比 Project Glasswing 合作伙伴的受限预览版更保守，且在长时间、多步骤任务及智能体式工作流上表现更强。Mythos 预览版于 2026 年 4 月推出，是当时最强前沿模型，尤其擅长编程、推理和网络安全（含发现零日漏洞）；因安全问题未公开，仅限 Project Glasswing 合作伙伴用于防御性网络安全，目前已报告发现数千个重大漏洞。

Anthropic Is dropping a public version of Mythos today： codename "Fable" - per The Information

It's costly， at 2x the price of Opus， but maybe still cheaper than what people expected after seeing the first Mythos pricing at 5x Opus.

- It will come with strong safety limits， and it will not be as open on cyber use as the restricted preview given to Project Glasswing partners.
- It is expected to be much stronger at long-running， multi-step tasks and agent-style workflows.

Context on Mythos：

- Anthropic introduced Claude Mythos Preview in April 2026. At launch， it wasit's most powerful frontier model， especially strong in coding， reasoning， and cybersecurity， including finding and exploiting zero-days.

- It was not released publicly at first because of safety issues. Only selected Project Glasswing partners received access for defensive cybersecurity， and they have reportedly found thousands of major vulnerabilities.
