🤖 Anthropic launches Claude Fable 5 and Mythos 5

Anthropic released Claude Fable 5 and Mythos 5. Claude Fable 5 is a Mythos-class model with cybersecurity protections for broad use. It leads on nearly all benchmarks in code, analytics, vision, and science, widening its lead as tasks get harder.

Mythos 5 is the same model without security limits, available only to Project Glasswing members. Both cost $10/$50 per million tokens, less than half the price of Mythos Preview. Stripe migrated 50 million lines of Ruby code in a day using these models, a task that took months before.
