What is Anthropic’s Claude Mythos model?

On April 7, Anthropic, the AI company behind the coding and productivity-focused Large Language Model (LLM) family Claude, announced Mythos. This is its most powerful model yet, capable of finding bugs in old software that have not been flagged by humans so far. Anthropic said that it would not release the LLM widely, but only to a consortium of over 40 companies, which will use it to scan decades-old code to find software vulnerabilities not detected by humans yet.

Claude is an LLM developed by San Francisco-based Anthropic, like OpenAI’s ChatGPT and Google’s Gemini. However, its reputation for quality outputs in fields such as coding have lent it a reputation unlike any other LLM on the market. Claude runs through a command-line interface as well as a suite of apps for different platforms, published by Anthropic.
