Why this one

What makes Nano Banana Pro different

Eleven aspect ratiosMore framings than any other image model here, including an automatic option and ultrawide.
4K outputThe top tier renders at 4K, which matters for print, for large screens and for anything that will be cropped.
References that actually holdUp to 4 stills, and it is unusually good at keeping a face or a product recognisable across them.
Eight images per runBatch a full set and pick, rather than paying eight times for eight tries.
Strong at compositionIt reads spatial instructions well: what is in front, behind, left and right.
The same price at 1K and 2KTwo of the three tiers cost the same, so there is no reason to draft below 2K.

Technique

Prompt tips

Describe the frame, then the subjectCamera position, lens feel and crop first. It follows photographic direction closely.
Use references for identityUp to 4 stills locks who or what is in the picture far better than any description will.
Name the lightSource, direction, hardness and colour. It is the difference between a photo and a render.
Batch and chooseEight per run is cheap per image. Generate the set before refining the prompt.
Go straight to 2KIt costs the same as 1K, so drafting lower saves nothing.

Mechanism

How Nano Banana Pro works

You give it a prompt and up to 4 reference images, and it composes a single still per output, generating up to eight in one run. Resolution is a price and detail axis rather than a different model, so a composition you like at 2K holds at 4K, which makes the batch then upscale workflow reliable.

Questions

Nano Banana Pro FAQ

How many reference images can I use?

Up to 4 per run, and this model is unusually good at keeping a face or a product recognisable across them.

Is 4K worth the extra credits?

For print, for large screens and for anything that will be cropped in, yes. For web placement at normal sizes, 2K is usually enough.

How many images per generation?

Up to 8, which is the cheapest way to explore a prompt before committing to a direction.

Can it keep a character consistent?

Yes, with references. Reuse the same stills on every run and the subject stays recognisable.

Nano Banana Pro or Nano Banana 2?

Pro for finals and for hard compositions. 2 is faster and cheaper for volume.
