20 сент. 2026 г. · API Many

GPT Image and Google’s Nano Banana family are the two image APIs most teams start with. Both handle text-to-image and editing well; the differences show up in typography, multi-image consistency and cost at high resolution.

Choose GPT Image when

  • The image contains text that must be exactly right: posters, menus, UI mockups, infographics.
  • You describe layouts precisely and want them followed.
  • You need many low-cost drafts at 1K with GPT Image 2.

Choose Nano Banana when

  • You edit conversationally: "make it winter", "swap the outfit".
  • You need the same character across many images from several references.
  • You want up to 4K output for final assets.

Price

GPT Image 2 starts at от $0.011/ изображение and Nano Banana 2 at от $0.019/ изображение. Both run through POST /v1/images/generations, so you can A/B the same prompt on both and keep the winner.
