Claude Opus 5
Anthropic positions Opus 5 as the model to reach for by default rather than to ration: it launched at $5/$25 per MTok, half the price of the previous Opus flagship, while keeping the 1M-token context window and multimodal text, image and file input. It sits below Fable 5 in the Claude ladder and above Sonnet 5.
Claude Opus 5 is a frontier AI model from Anthropic. It costs $5.000 per million input tokens and $25.000 per million output tokens (blended $11.000/M), with a 1,000,000-token context window.
