A proposito di questo modello
Claude Fable 5.1 is Anthropic's newest flagship model, built for long-horizon agentic coding, multistep research, and document, spreadsheet, and slide work. It runs with adaptive extended thinking always enabled (steerable via effort, from low up to max) and a 1 million token context window with up to 128K tokens of output. It accepts both text and image inputs — charts, tables, PDFs, and screenshots — for multimodal analysis, and is a step up in reasoning depth from the earlier Claude Fable 5. Pricing is token-based: $10.00 per million input tokens and $50.00 per million output tokens.

Chiesto frequentemente
Claude Fable 5.1 is Anthropic's newest flagship language model, built for long-horizon agentic coding, multistep research, and document, spreadsheet, and slide analysis, with a 1M-token context window and always-on adaptive extended thinking.
Pricing is token-based: $10.00 per million input tokens and $50.00 per million output tokens. The minimum charge per call is $0.0008. Actual cost is deducted after each call based on token counts returned by the model.
/claude-fable-5-1 is async — you receive a request_id and poll for the result. /claude-fable-5-1/stream returns a live SSE stream. Use streaming for chat UIs; use the async endpoint for workflows and automation.
Yes. Pass an image_url in the request body to include an image — such as a chart, table, PDF page, or screenshot — as part of the user message for multimodal analysis.
Claude Fable 5.1 adds a larger 1M-token context window, always-on adaptive extended thinking (steerable via effort), and stronger long-horizon agentic and research performance compared to [Claude Fable 5](/playground/claude-fable-5).
Extended thinking is always enabled and cannot be turned off, but its depth is adaptive to the task — harder, multistep requests automatically get more reasoning effort.
