What it is good at

  • Speed and volume: ByteDance calls it the fast, cost-efficient tier of Seedream 5.0, made for high-volume work.
  • Precise edits at low latency, with up to 10 input images as references.
  • Flexible sizes: pick a preset or set your own width and height inside the allowed range.

Honest limits

  • Total pixels must stay between 1024 x 1024 and 2048 x 2048, so there is no 4K size.
  • One request makes up to 6 pictures.
  • This is the Flash tier; ByteDance also makes Lite and Pro versions of Seedream 5.0, which Ziztu does not use.
