Anthropic may have just announced the future of AI – and it is both very exciting and very, very scary.
Mythos is the Ancient Greek word that eventually gave us ‘mythology’. It is also the name for Anthropic’s latest foundational AI Model: it evokes the connective tissue that links together knowledge and ideas.
Industry excitement over Anthropic’s Claude Mythos began at the end of March 2026 when Fortune magazine published information on an upcoming Anthropic development. The information came from a leak of almost 3,000 files from a misconfigured CMS. Anthropic confirmed the details.
