Anthropic's unreleased 'Mythos 1' AI model repeatedly appears online despite the company claiming restricted access. The model, associated with Anthropic's Claude Code system, has been accessed and documented by users who circumvented intended limitations, raising questions about the company's control over its AI deployments.
Anthropic announced a run rate revenue of $47 billion, raised $65 billion in a Series H round, and achieved a post-money valuation of $965 billion.
Simon Willison argues Anthropic and OpenAI have found product-market fit through enterprise coding agents. Both companies shifted to API-based enterprise pricing, and recent models cost more. Stories of Uber blowing its AI budget and Microsoft canceling Claude Code licenses suggest customers are paying high prices for genuinely useful tools, making April 2026 a new revenue inflection point.
