Anthropic Offers Mythos Preview to Cybersecurity Partners
Anthropic launched Project Glasswing, granting select Big Tech and security vendors access to an unreleased general-purpose model, Claude Mythos Preview, for defensive cybersecurity work. Partners — including Amazon, Google, CrowdStrike and Palo Alto Networks — will use the model to hunt vulnerabilities; Anthropic says Mythos Preview found "thousands" of major vulnerabilities in operating systems, browsers and other software. The company is extending access to roughly 40 organizations responsible for critical software infrastructure and committed up to $100 million in usage credits plus $4 million to open-source security groups. Anthropic is also in ongoing discussions with the U.S. government and frames the effort as a step toward safely deploying Mythos-class models at scale.
Scoring Rationale
The story directly affects security and ML practitioners: an advanced model is being provisioned to industry partners for vulnerability discovery, with significant credits and coordination. It's not industry-defining like a major model open release, but it materially shifts how security teams will integrate LLMs and elevates dual-use risk concerns.
