Hot, fresh, and worth queueing round the block for.
Summary
Anthropic has launched Project Glasswing, restricting access to its new Claude Mythos AI model to a select group of security researchers and preview partners. The company claims the model's cybersecurity capabilities are so advanced—having already discovered thousands of high-severity vulnerabilities across major operating systems and web browsers—that the broader software industry needs time to prepare before wider release. This controlled rollout approach aims to balance innovation with security concerns.
