Overview
- The European Commission met with Anthropic in San Francisco on Thursday to press for greater technical access and understanding of Mythos‑class models.
- Anthropic has kept Mythos access limited to a vetted preview called Project Glasswing and has not granted the EU or most non‑U.S. governments preview rights.
- Anthropic told EU officials that sharing with non‑U.S. governments would require consultation with the U.S. administration, which officials say is broadly cautious about wider distribution.
- Security experts and Anthropic leadership say Mythos can find and chain software vulnerabilities quickly, creating a narrow window to patch flaws before competitors catch up.
- Regulators and financial authorities are intensifying coordination and technical reviews, and rival labs and governments are exploring controlled previews and common standards to manage dual‑use risk.
