Pricing checked against provider documentation on . How we verify
The short answer
FLUX.2 [pro] is the cheaper option — roughly 4.5x less on a blended workload, and it suits cheapest flagship-tier image quality. Nano Banana Pro justifies its premium when you need multi-image compositing and iterative edits.
Black Forest Labs • FLUX.2
$0.03 / $
/ image (input / output)
The best quality-per-dollar in hosted image generation, at three cents for a 1024² render through the official API, fal.ai, or Replicate alike. Note that Replicate prices by megapixel, so feeding in reference images for an edit pushes a single call closer to $0.055.
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 4.5x the price than FLUX.2 [pro] on input tokens.
