Anthropic Releases Next-Generation Mythos-Class Model Within Weeks After Safety Breakthroughs

According to Anthropic's official announcement, the company confirmed that it will release its next-generation Mythos-class model to all customers within weeks following breakthrough progress in safety defense mechanisms. The announcement came after May 22, when the Glasswing software security project report had emphasized that the company would not publicly release Mythos-class models until more robust safety mechanisms were developed.

The Mythos-class model has faced deployment delays due to a significant time disparity in attack-defense capabilities: vulnerabilities could be discovered in seconds but require weeks to patch. Anthropic is accelerating development of enhanced safety defense systems and has already begun providing defensive scanning tools to qualified security teams to establish asymmetric advantages in threat mitigation.
