Pricing checked against provider documentation on . How we verify
The short answer
FLUX.2 [pro] is the cheaper option — roughly 2.2x less on a blended workload, and it suits cheapest flagship-tier image quality. Nano Banana 2 justifies its premium when you need fast generation with multilingual text.
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
$0.07 / $
/ 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.
Input price
Nano Banana 2 is 2.2x the price than FLUX.2 [pro] on input tokens.
