A new Anthropic model found security problems ‘in every major operating system and web browser’

Why it matters: Anthropic's AI will automatically reveal high‑severity bugs to 40+ software firms, prompting immediate patches.
- Anthropic launches Project Glasswing, delivering Claude Mythos Preview to defensive‑security partners while keeping it out of public hands.
- Claude Mythos Preview autonomously flagged “thousands of high‑severity vulnerabilities, including some in every major OS and web browser,” according to Anthropic’s blog.
- Partner firms such as JPMorgan Chase, Cisco, CrowdStrike, the Linux Foundation and about 40 other organizations receive up to $100 million in usage credits and $4 million in donations.
Anthropic’s new Project Glasswing gives defensive partners access to Claude Mythos Preview, an AI that autonomously uncovered thousands of high‑severity bugs across every major operating system and web browser. The model is being rolled out privately to a select group of security‑focused firms, with Anthropic pledging up to $100 million in usage credits and donations to open‑source foundations.
