# Seedream 5.0 Pro

> Seedream 5.0 Pro text-to-image and image-to-image. Pass `image_list` to use reference images (up to 10), or omit it for pure text-to-image. Always returns a single image — this model does not support sequential (grouped) image generation.

**Pricing:** output is 2.25 tokens for 1K (= $0.045) and 4.5 tokens for 2K (= $0.090). Each reference image in `image_list` adds 0.15 tokens (= $0.0030). Example: 2K with 3 reference images = 4.5 + 3 × 0.15 = 4.95 tokens.

Returns an `img_uuid`; poll GET /api/v1/jobs/detail (or use `custom_callback_url`) to get the generated image.

                    is retried up to 3 times, with a 3-second timeout per
                    attempt.
