  • Image generation

Seedream 5 Pro is ByteDance's flagship model for text-to-image generation and image editing, accepting up to 10 reference images for character and style consistency.

Output quality is selected with the `size` parameter: 1K is roughly 2 megapixels and 2K roughly 4 megapixels. Omit it and the model runs at 2K.

Pricing is per output image and follows the resolution you pick: $0.045 at 1K and $0.09 at 2K.

On Hormouz, Seedream 5 Pro runs as an asynchronous prediction job. You submit a request and collect the result when it is ready. Stable access from inside Iran, with no foreign credit card required.
