Claude Fable 5 and Claude Mythos 5
Anthropic's Mythos-class model, built for general use
Claude Fable 5 runs the same model as Mythos Preview with safeguards for public use. Built for software engineers, analysts, and researchers running long, complex, autonomous tasks.
Claude Fable 5 is Anthropic's first Claude 5 model: Mythos-class intelligence, now available for general use.
Most frontier AI models either cap out at task-level work or stay locked behind restricted programs. Fable 5 changes that. It runs the same underlying architecture as Claude Mythos Preview, which Anthropic has kept restricted to cyber defenders and critical infrastructure partners since April, but with safety classifiers applied so anyone can use it.
Compresses months of engineering into days (Stripe ran a full migration through a 50M-line Ruby codebase in one day)
Leads all models on Hebbia's Finance Benchmark for senior-level reasoning
Rebuilds web apps from screenshots with no additional tooling
Stays coherent and focused across millions of tokens in long-running autonomous tasks
Falls back to Claude Opus 4.8 on flagged topics, with user notification, affecting fewer than 5% of sessions
Built for software engineers, financial analysts, and researchers who need a model that can hold a long, complex task end-to-end without constant human check-ins.
