Claude Fable 5.2 and Mythos 5.2 cement Anthropic's AI lead just before its IPO
Anthropic 一次放出 Fable 5.2 和 Mythos 5.2 两款模型，号称能解决物理难题、设计操作系统，还包办了自家 90% 以上的代码合并。免费版可以直接试，想跑高敏感任务的团队得走组织验证那条路。
Anthropic 发布 Claude Fable 5.2 和 Mythos 5.2，称为其迄今最强大的模型，分两个版本：一个免费开放，另一个仅向通过验证的组织提供。
据公司介绍，新模型能解决开放性物理问题，具备更强的网络安全能力，可设计可运行的操作系统，并承担 Anthropic 核心代码库中超过 90% 被合并的代码变更。Anthropic 同时表示，已刻意限制模型加速自身开发的相关能力。
这一发布时间点恰逢 Anthropic 准备 IPO 之前，模型在代码与推理任务上的表现被视为巩固其行业领先地位的关键。对开发者和企业用户而言，免费版本降低了接入门槛，而验证组织专属版本则面向对能力和安全控制要求更高的场景。

Anthropic is releasing Claude Fable 5.2 and Mythos 5.2, its most powerful models to date, in two versions: one freely available and one reserved for verified organizations. The models solve open physics problems, show stronger cybersecurity capabilities, design functioning operating systems, and write more than 90 percent of the changes merged into Anthropic's core code, according to the company. Anthropic says it has deliberately curbed any capabilities that would let the AI accelerate its own development.
