Seedream 5.0 API · Common questions

Answers about pricing, inputs, integration and results.

How much does Seedream 5.0 cost?

Pricing is currently unavailable. Check the model status before submitting.

How do I get a NewRouters API key?

Sign in and open Quick Start above the workspace. Select or create a key with access to this model, then copy the request example.

Which inputs and output settings are supported?

Supported input fields: images, prompt, resolution, aspect_ratio, output_format. The parameter table includes allowed values and defaults.

Can I use reference images?

Yes. Use the reference mode to upload images or supply their URLs. The current limit is 10 images. Reference images guide a new generation; they do not imply mask editing support.

How do I retrieve results and past requests?

Save the returned task ID and query the task until it succeeds or fails. The History tab lets you reopen your tasks and reuse their parameters.

What happens if the model is closed?

The model keeps its page and identity, but new generation requests are blocked. Existing task records remain accessible. An upstream outage is reported separately from an administrator closing the model.
