FAQ about Seedream 4.5

What is the API ID of Seedream 4.5?

seedream-4.5 — put this into the model field of your request.

What does a generation request look like?

POST to /v1/images/generations with model, prompt and optionally n and size. The format matches the OpenAI Images API — only the base URL and the key change.

How do I set the image size?

With the size field, for example 1024x1024. The available set depends on the model; 2048x2048 is not supported everywhere, and even there the result sometimes comes back smaller — check the actual image.

What does one image cost?

Generations are taken from the key's image quota: one picture — 1×, and with n images per request it is n × the multiplier. See the documentation for details.

Can I edit an existing image?

No — this model only generates images from a prompt.

What comes back in the response?

A data array where each item holds a link to the finished image in the url field. Download the picture and store it on your side — the link is not meant for permanent hosting.
