Nano Banana Pro vs Seedream 4.5

Nano Banana Pro and Seedream 4.5 differ on 3 specifications — from what each one costs to which inputs it accepts. Every value below is read from the live model catalog, so it stays current as new versions ship.

Which should you use?

Seedream 4.5 reaches 3K and 4K at a flat 6 credits, less than half Nano Banana Pro's entry price for the same ceiling. Nano Banana Pro's edge is image editing and a 1K tier for cheap tests.

Seedream 4.5 covers 3K and 4K at a flat 6 credits. Nano Banana Pro covers 1K, 2K and 4K from 15 to 28, and handles editing as well as generation.

For pure generation at large sizes, Seedream 4.5 delivers the same 4K ceiling for less than half the entry price, with no pricing variability to reason about. That is a strong default for finished high-resolution work.

Nano Banana Pro earns the difference two ways: it can edit an existing image, which Seedream cannot, and its 1K tier gives you a cheap pass for testing composition before committing. If neither of those matters to your workflow, the price gap is hard to argue with.

Pick Nano Banana Pro when

  • You need image editing, not just generation.
  • You want a 1K tier for cheap iteration; Seedream 4.5 starts at 3K.

Pick Seedream 4.5 when

  • Cost is the constraint — a flat 6 credits against 15 to 28.
  • You need 3K or 4K output and nothing else.
