How is Nano Banana 2 different from Nano Banana Pro?

Nano Banana 2 is gemini-3.1-flash-image, tuned for speed; Pro is gemini-3-pro-image, tuned for instruction following. Pro wins on complicated multi-subject shots; 2 wins on everything you are going to regenerate a few times.

Is there a cheaper version?

Nano Banana 2 Lite, at roughly 40% of the price. It is the fastest model in the catalog and a good fit for rough boards.

Can I use it inside a reel?

Not currently — the reel pipeline publishes GPT Image 2, Nano Banana Pro and Seedream 5.0 Pro. Nano Banana 2 is available for standalone image generation.

Nano Banana 2

Nano Banana 2 is Google's gemini-3.1-flash-image — newer than the original Nano Banana, cheaper than Pro. For most storyboard work it is the setting you leave it on: fast enough to re-render a board, accurate enough that you rarely regenerate a shot twice.

The Balanced Choice

Roughly twice the price of the original Nano Banana and about a quarter less than Pro. In practice that buys noticeably better prompt adherence without the Pro latency.

Cheap Enough to Redo

Storyboarding is iterative. A model you hesitate to re-run is a model that makes you settle for the first result.

Same Reference Pipeline

Character, location and prop references bind identically across the Nano Banana family — switching models does not mean rebuilding your asset library.
