Common Questions

Frequently asked

What is Seedream 5.5?

Seedream 5.5 is ByteDance's image generation model with improved photographic realism, aesthetics, native transparent-background output and 1K, 1.5K and 2K tiers.

How much does the Seedream 5.5 API cost?

$0.02 per image at 1K and 1.5K and $0.035 at 2K. Pay per generation with no subscription.

Which aspect ratios are supported?

Eight ratios: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2 and 21:9, set with `aspect_ratio`.

Can it output a transparent background?

Yes. Set `background` to `transparent` with `output_format` png to receive an image with an alpha channel.

Does Seedream 5.5 support a spicy mode?

The Seedream 5.5 API applies standard content-safety moderation, so explicit adult output is not guaranteed and prompts that trigger the filter are rejected and refunded. If you need a less restricted tier for mature creative work, see the Spicy models on Muapi, such as [Seedance 2.5 Spicy](/seedance-2.5-spicy) for video.

How do I get the result?

Requests are asynchronous: submit a job, then poll the returned `request_id` or pass a `webhook` URL to be notified on completion.

Is there a sandbox for testing?

Yes. Sandbox API keys return mock results instantly with no credits deducted.
