Nano Banana 2 is Google's Gemini 3.1 Flash Image model. It creates images from a text prompt and edits existing ones from plain-language instructions — say 'add a sunset glow', 'replace the chair with a throne' or 'remove the background' and it applies the change. Attach reference images and it switches to editing automatically. Nano Banana 2 Lite is a lighter, cheaper variant.
Intuitive Natural Language Editing
Describe the change in plain language and Nano Banana 2 applies it — object swaps, background changes, facial refinements, style shifts.
Text-to-Image Too
Not only edits: describe a scene from scratch and Nano Banana 2 draws it; attach references and it edits instead.
Precision Object & Background Editing
Pixel-level object replacement, background modification, and facial refinement without distortions across iterations.
Physics-Aware Outputs
Edits maintain coherent lighting, natural shadows, and correct spatial relationships — outputs look real, not pasted.
Nano Banana Pro is powered by Gemini Pro Image — Google's most capable image model. It generates up to 4K resolution output, accepts up to 8 reference images that are blended into a single coherent result, and operates with a 64K input context window. Multi-turn dialogue editing lets you refine outputs without full regeneration, and search-grounded generation draws on Google's knowledge base for accurate diagrams, infographics, and scientific visuals.
4K High-Fidelity Output
Generate at 1K, 2K, or 4K resolution — ideal for print, product photography, and high-fidelity brand assets.
8-Image Composition
Blend up to 8 reference images into one coherent output — consistent lighting, perspective, and style across all inputs.
64K Context Window
64K input context enables complex multi-image instructions, long creative briefs, and intricate multi-step editing sequences.
Multi-Turn Editing
Refine your image through dialogue — ask for adjustments, tweak specific elements, and iterate without restarting from scratch.
It depends on the job. Nano Banana 2: Gemini 3.1 Flash Image — Fast Generation and Plain-Language Edits. Nano Banana Pro: Gemini Pro Image — 4K Output, 8 References, 64K Context. Both are on The Factory on one credit balance, so you can run the same prompt on each and keep the better result.
