Anthropic is holding back its new AI model, Claude Mythos Preview, and teaming up with over 40 tech firms to hunt and patch security flaws in critical software. The company says the model can autonomously find zero-day vulnerabilities that have eluded researchers for decades, raising fresh concerns about AI-driven cyberattacks.

• Anthropic is withholding public release of Claude Mythos Preview and instead giving early access to ~40 companies (Apple, Amazon, Microsoft, Google, Cisco, Broadcom, Linux Foundation) under "Project Glasswing," backed by up to $100 million in usage credits, to find and patch critical software vulnerabilities first.
• The model has reportedly found a 27-year-old vulnerability in OpenBSD and a flaw in video software that survived five million automated scans, using simple prompts to autonomously hunt zero-days.
• Anthropic frames this as a security "reckoning" while simultaneously racing toward projected revenue of $30 billion this year, mirroring the tension of building powerful AI it also warns could enable dangerous cyberattacks.
