Nano Banana Pro vs Seedream 5.0 Pro

Nano Banana Pro and Seedream 5.0 Pro 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?

Nano Banana Pro is the one to pick when the image has to be delivered large — it reaches 4K where Seedream 5.0 Pro stops at 2K — but Seedream costs roughly half, which makes it the better model to iterate on.

Both are current-generation image models and the specs separate them cleanly. Nano Banana Pro offers 1K, 2K and 4K from 15 credits, and covers both plain generation and image editing. Seedream 5.0 Pro offers 1K and 2K from 7 credits.

So the decision is the familiar one between iteration cost and delivery ceiling. At roughly half the price, Seedream gives you twice the attempts for the same spend, which matters most in the phase where you are still finding the image rather than refining it. Nano Banana Pro is the only one of the two that can hand you a 4K master.

If your work reliably ends up on a screen at web sizes, the 4K tier is capacity you are paying for and not using, and Seedream 5.0 Pro is the more economical default. If anything gets printed, or crops hard, or goes on a large display, the ceiling is the whole argument.

Pick Nano Banana Pro when

  • The output is being printed, or used at a size where 2K would show.
  • You need image editing as well as generation; Nano Banana Pro covers both under one model.
  • The composition is settled and this is the take that ships.

Pick Seedream 5.0 Pro when

  • You are still exploring and want more attempts per credit — 7 against 15 at entry.
  • 1K or 2K is the delivery size, which covers most web and social use.
  • You are generating variations in bulk to pick from.
