Nano Banana 2.1 vs GPT Image 2.5
Nano Banana 2.1 and GPT Image 2.5 belong to different providers' image model families. Google's documentation identifies Nano Banana 2.1 directly; OpenAI's 2.5 API family has Flare and Sunburst variants. Both relay options passed a square text-to-image test, but the responses do not independently establish upstream model identity or the GPT Image 2.5 variant. Other sizes and reference-image inputs remain unverified. Compare the published examples, confirmed controls and current per-image credit costs here; no quality or speed winner is claimed.
