Anthropic 终于把最强模型 Mythos 公开了，虽然价格不菲但比预期便宜，做复杂智能体任务和长流程自动化的团队可以直接评估是否值得投入。
Anthropic 于今日推出 Claude Mythos 的公开版本，代号“Fable”。该模型定价为 Opus 的两倍，但低于此前 Mythos 预览版 5 倍 Opus 的传闻价格。Fable 将附带严格的安全限制，在网络安全使用上不如之前给 Project Glasswing 合作伙伴的受限预览版开放。该模型在长周期、多步骤任务和智能体工作流方面预计表现更强。Mythos 最初于 2026 年 4 月以预览形式推出，在编码、推理和网络安全领域能力突出，但因安全问题未公开发布。

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.
