Pricing
Pricing is based on the number of tokens used. For tool-specific models, like search and computer use, there's a fee per tool call. See details in the pricing page.

Headline rates cover text input and image output; image input is billed separately at $10.00 per million tokens, with cached image input at $2.50. Because billing is per token rather than per image, a generated image works out to roughly $0.011 to $0.016 at low quality, $0.042 to $0.063 at medium and $0.167 to $0.25 at high, depending on resolution.
