Nano Banana 2.1 is the everyday image model: fast, accurate to the prompt, and cheap enough that you can iterate rather than agonise. It accepts one to four reference images, which is what makes it practical for product work — feed it the actual product and it keeps it recognisable.
Native output is around 1K. There is no 4K upscale on this tier; that belongs to Nano Banana Pro. If you want the fastest and cheapest member of the family, Nano Banana 2 Lite renders at half the price.
For most briefs the honest recommendation is: start on Lite, move to Nano Banana 2.1 when the composition matters, and only reach for Pro when you need the 4K.
