By PulseAugur Editorial · [1 sources] ·

Anthropic's next-generation AI model, codenamed Capybara and internally referred to as Claude Mythos, has been revealed through an accidental data leak. This new tier is reportedly positioned above Opus and demonstrates significantly improved performance in coding, reasoning, and cybersecurity compared to Claude Opus 4.6, though specific metrics are not yet public. The leak also indicated high serving costs for Claude Mythos, with Anthropic planning further efficiency optimizations before any potential general release. The mention of advanced cybersecurity capabilities in the leaked documents caused a brief but notable dip in cybersecurity stock prices. AI
