The update
Anthropic has officially launched the preview version of its most powerful model, Claude Mythos, which significantly outperforms Opus 4.6. Tests indicate that Claude Mythos possesses strong code analysis capabilities, able to identify thousands of high-risk vulnerabilities, with potential attack skills surpassing those of most hackers. Due to the extremely high security risks associated with the model, Anthropic has decided not to make it available to the public for now. Currently, the model is only accessible to tech giants such as Amazon, Apple, and Google, as well as over 40 critical infrastructure companies, through a special initiative called Project Glasswing. These partners will use the model for defensive security hardening to enhance system safety.
