1,000,000 context · $10.00/M input tokens · $50.00/M output tokens
Claude Fable 5 is Anthropic’s generally available Mythos-class model for autonomous knowledge work, advanced reasoning, and long-horizon coding. It supports text, image, and file inputs with text output, a 1M-token context window, up to 128K output tokens, always-on adaptive thinking, tool use, and structured outputs. Built from the same underlying model family as Claude Mythos 5 with stronger public-release safeguards, it is suited for complex software engineering, multi-step agent workflows, enterprise research, document analysis, and professional tasks that require sustained reasoning and reliability.

Anthropic: Claude Fable 5
Claude Fable 5 is Anthropic’s generally available Mythos-class model for autonomous knowledge work, advanced reasoning, and long-horizon coding. It supports text, image, and file inputs with text output, a 1M-token context window, always-on adaptive thinking, tool use, and structured outputs.
Why It Looks Great
- Anthropic’s most capable widely released model for demanding reasoning and long-horizon agentic work
- Mythos-class capability made generally available with robust public-release safeguards
- 1M-token context window for large codebases, long documents, research corpora, and extended multi-turn workflows
- Up to 128K output tokens for long-form reasoning, coding, analysis, and structured generation
- Strong fit for autonomous software engineering, enterprise knowledge work, scientific analysis, and complex planning
- Vision and file input support for screenshots, diagrams, PDFs, documents, and multimodal analysis
- Always-on adaptive thinking for deeper reasoning without manual thinking-mode configuration
- Function calling and tool-use support for agentic application workflows
- Structured output support for JSON responses and schema-constrained generation
