What Seedream 4.5 is for

Anything going out at 4K — it is the only model here that does not charge more for the larger size.
Social and vertical video stills: 18 aspect ratios, including 9:19.5, 9:20 and 2:1, which nothing else here offers.
Volume — 10 images per call, so a large batch does not fan out into ten separate round trips.
Reference-led work, with up to 14 input images.

When not to use it

If the picture needs readable text in it, GPT Image 2 is the safer choice.

Model	Maker	Max res	Ratios	Refs
Nano Banana 2	Google	4K	14	14
Nano Banana Pro	Google	4K	10	14

A dash under “Max res” means the model has no resolution setting to choose — it returns its own native size — not that it is limited to a small one. “Text in image” marks the model with per-tier quality control and a background setting — GPT Image 2 — which is the one built for legible type and clean cut-outs.
