}Generate image with SeeDream 5.0 Flash
ByteDance SeeDream 5.0 Flash — fast, low-cost text-to-image and image editing with multi-reference composition from up to 10 reference images and 1K/2K output, typically in under 20 seconds. Can keep a transparent background when editing a PNG cutout. Billing: a flat 25 credits per image at 1K or 2K; input images are free. No grouped/sequential generation.
Asynchronous. Returns a job id (the image is not in this response). Poll GET /v1/images/{id} until status is succeeded — the generated image URLs are in that response’s images array (each { url, position }).

Body
Text description of the image to generate.
Output aspect ratio.
1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, 21:9, 9:21 Output background. "transparent" keeps a transparent background when editing: it needs exactly one input image, a PNG that already has transparent pixels (a cutout, sticker or logo), and returns a PNG with an alpha channel. Text-to-image and multi-reference requests must use "opaque".
opaque, transparent Number of images to generate.
1 <= x <= 4Optional reference images (up to 10) for image editing and multi-reference composition. Each item is a public image URL, a data URI, raw base64, or an uploaded-file URL from POST /v1/uploads. Omit for text-to-image. Input images are free.
10Output resolution. Both tiers bill the same 25 credits per image.
