Claude Fable 5

Frontier

Anthropic's most powerful model — a new tier above Opus. Fable 5 keeps the 1M-token context window and multimodal input (text, image, file), and targets the hardest long-horizon agentic, coding and reasoning work. Priced at $10/$50 per MTok with $1.00 cached input.

Claude Fable 5 is a frontier AI model from Anthropic. It costs $10.000 per million input tokens and $50.000 per million output tokens (blended $22.000/M), with a 1M-token context window.
