What is Claude Fable 5?
Claude Fable 5 is Anthropic's frontier model announced June 9, 2026 — built for complex knowledge work and coding that runs for hours or days. It accepts text, images, and PDFs, and returns text. Vision is a headline strength: extracting numbers from scientific figures, rebuilding apps from screenshots, and evaluating code against designs. Anthropic explicitly positions Claude as image-understanding only; for creating marketing visuals or product shots, use a dedicated image generator on FreeMake instead.
Vision state of the art
High-resolution image input (up to 2576 px on the long edge) for screenshots, UI mockups, and dense documents.
Coding & agents
Plans across stages, delegates sub-tasks, writes tests, and self-verifies — suited to long asynchronous workflows.
Document intelligence
Reads nested tables, charts, and figures inside PDFs — strong for finance, legal, and analytics workflows.
1M-token context
Up to 1M input tokens and 128K output tokens for large codebases and multi-file reviews.
