09 / FAQ

Things teams ask.

Q.01What's it best at?
Three things: (1) authentic East-Asian aesthetic in fashion, food, and architecture, (2) bilingual or CJK typography, (3) multi-reference workflows where you need to fuse multiple inputs into a single output.
Q.02Can I pass multiple reference images?
Yes — Seedream is the strongest model in the catalog at multi-reference. Pass an array of image URLs alongside your prompt; the model holds visual identity across all references.
Q.03How does it handle Western faces and content?
Competitive but not category-leading. For US/EU portrait photography, GPT Image 1.5 or Imagen 4 are better picks. For everything else, Seedream is comparable to FLUX at lower cost.
Q.04Can I use the outputs commercially?
Yes. Infer passes through ByteDance's commercial terms for Seedream outputs.
Q.05What are the rate limits?
Default tier is 60 requests per minute, with burst capacity to 120/min.
Q.06How is this different from calling ByteDance directly?
One key, one bill, one SDK shape across 100+ models, no regional account friction.
