Nanobanana Pro and GPT Image 1 for real workflows
Nanobanana Pro is provided by Google and emphasizes up to 4k and sharp text. GPT Image 1, from OpenAI, emphasizes reliable output and prompt fidelity. The stronger option depends on the input, output constraints, and review standard.
How to test Nanobanana Pro vs GPT Image 1
Run the same prompt, source context, output format, and acceptance criteria through both models. Score accuracy, instruction following, edit time, latency, and current cost separately. Repeat the test on several representative tasks before standardizing on either model.
