Nano Banana 2 vs Nano Banana Pro
Google's Nano Banana 2 and Google's Nano Banana Pro both target image generation, but they price and behave differently. Here is the side-by-side.
Pricing checked against provider documentation on . How we verify
The short answer
Nano Banana 2 is the cheaper option — roughly 2.0x less on a blended workload, and it suits fast generation with multilingual text. Nano Banana Pro justifies its premium when you need multi-image compositing and iterative edits.
Google • Gemini Image
$0.07 / $
/ image (input / output)
Renders in roughly 1.4 seconds and handles text in over 30 languages including non-Latin scripts, which is unusual. Google bills it by output tokens rather than per image, so the price scales with resolution — a 4K render costs more than three times a 512px one.
Google • Gemini Image
$0.13 / $
/ image (input / output)
Google's premium image tier, aimed at workflows that feed several source images in and refine the result across turns rather than generating one-shot. The most expensive option in this table at 4K, and the batch lane halves it for anything that does not need a synchronous response.
Input price
Nano Banana Pro is 2.0x the price than Nano Banana 2 on input tokens.

Nano Banana 2: 1024² render. Priced at $60 per million output tokens, so cost tracks resolution: $0.045 at 512px, $0.067 at 1K, $0.101 at 2K, $0.151 at 4K. Batch mode halves all of these.
Nano Banana Pro: 1K–2K resolution on the standard tier; 4K is $0.24. Batch and Flex lanes cut both roughly in half, to $0.067 and $0.12.
