Seedream 4.0

You type a prompt in Chinese or English, or drop in up to six reference images, and Seedream 4.0 returns a 2K image in roughly 1.8 seconds.

Seedream 4.0 is an AI image generator and photo editor that covers text to image, image to image, editing and photo restoration under one roof.

The speed is credited to its MoE architecture, which is a technical claim you can test yourself with a few runs.

The reference-image support is the detail that matters most if you care about control.

Feeding in several images lets you steer style, subject or composition instead of relying on words alone.

The tool can also produce up to nine images at once, and its batch generation is meant to keep a set of outputs consistent with each other.

That is handy for product shots, campaign sets or a series of illustrations where the pieces need to look related.

Native bilingual prompting means you do not need to translate Chinese briefs into English first.

Paid plans include a commercial license, so check that before using results in client work.
