Claude Fable 5

Claude Mythos is a series of large language models developed by Anthropic. It is the most powerful series of models in the Claude family. The first model in the series was Claude Mythos Preview. Anthropic did not release the model to the public, citing the model's ability to find software vulnerabilities. Access to Claude Mythos was provided to some companies in the context of Project Glasswing to scan for security vulnerabilities in critical software. The public had mixed reactions to the announcement of Claude Mythos Preview.
