| GPT Image | Nano Banana | |
|---|---|---|
| Maker | OpenAI | Google DeepMind |
| Current model | GPT Image 2 (April 21, 2026) and ChatGPT Images 2.5 (September 8, 2026) | Nano Banana 2 (February 26, 2026) and Nano Banana 2 Lite |
| Resolution | Up to 2K in the API | 512px to 4K |
| Consistency | OpenAI highlights detail preservation when editing | Google says it keeps the resemblance of up to five characters and the fidelity of up to 14 objects in a workflow |
| Where you use it | ChatGPT and the OpenAI API | Gemini app, Google Search, Gemini API and Vertex AI |
| Best for | Detailed instructions, layouts and text | Storyboards, consistent characters and fast edits |
If you already live in ChatGPT, GPT Image is the convenient choice. If you work in Google's tools or need many consistent characters across a storyboard, Nano Banana 2 is worth testing. Both makers' claims are their own: test with your images.
Both tools are made by the two largest AI labs and are built into their assistants. The right choice often depends on the ecosystem you already use.
Build a three-panel storyboard with the same character in each panel. Check how well each keeps the face, clothes and props identical, then try an edit that changes only the background.
