Anthropic to launch Claude Fable today, a security-hardened version of the Mythos model

TechFlow news: On June 9, according to The Information, sources indicated that Anthropic may release its new model, Claude Fable, today. Described as a secure version of Mythos, Claude Fable retains some advanced capabilities while introducing enhanced security restrictions for high-risk scenarios such as cyberattacks. Anthropic previewed Mythos in April this year, highlighting its ability to discover numerous previously unknown cybersecurity vulnerabilities—but refrained from releasing it directly due to potential security risks. As of now, Anthropic has not officially disclosed detailed information about Claude Fable.
