Image Generation Model Pricing

Image generation models may use different billing methods. Some models are billed by text, image input, and image output tokens, while others are billed by each generated image. Check the billing unit shown for each model before estimating cost.

Under the platform-wide conversion of 1 USD = 1,000,000 Credits, USD X / 1M Tokens corresponds numerically to X Credits/Token for token-based pricing.
