Anthropic restricts Claude Mythos to Project Glasswing

The launch of Mythos signifies a pivot from AI as a chatbot to AI as a systemic threat, necessitating a controlled, infrastructure-first defensive posture. The model achieves a record 93.9% SWE-bench Verified score and has autonomously discovered decades-old bugs in OpenBSD and FFmpeg. Project Glasswing establishes a new precedent for cleared AI access restricted to critical infrastructure and financial sectors, while Treasury Secretary Scott Bessent’s intervention underscores the growing speed gap where AI-driven exploits outpace institutional security patching cycles. Gated availability via AWS and Google Cloud suggests that future high-capability models may never see a general public release.
