What is Claude Fable 5?
Claude Fable 5 is Anthropic’s most capable generally available model, designed for ambitious coding and professional work that can run for hours or days. Anthropic describes it as a Mythos-level model that plans across stages, delegates to sub-agents, checks its own work, and sustains complex projects with less supervision.
- Long-horizon agent work: plans multi-stage tasks, delegates work, and validates results
- Advanced coding: handles large migrations, complex implementations, testing, and autonomous coding sessions
- Knowledge work: supports deep research, analysis, and review-ready professional deliverables
- Vision understanding: interprets diagrams, charts, tables, screenshots, and document-heavy inputs
- Self-verification: proactively tests and reviews its output against the original goal
Anthropic prices Claude Fable 5 at $10 per million input tokens and $50 per million output tokens. The provider also applies additional safeguards to some cybersecurity, biology, chemistry, and distillation requests; flagged requests may be handled by Claude Opus 4.8 instead.
