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.
GPT Image 2 is OpenAI's next-generation image model with near-perfect text rendering, pixel-level editing precision, and strong photorealism. It accepts up to 16 reference images for image-to-image transformations and generates results in approximately 3 seconds. Ideal for product photography, branded visuals, multilingual creatives, and detailed multi-object compositions.
Near-Perfect Text Rendering
Renders legible, correctly spelled text inside images — signs, labels, multilingual creatives, UI mockups — with higher accuracy than any previous generation.
Pixel-Level Editing
Precise image editing with preserved lighting, shadows, and textures — replace objects, refine backgrounds, and apply changes without visual artifacts.
Up to 16 Reference Images
Supply up to 16 reference images to guide transformations — maintain brand identity, character consistency, or style across generations.
Fast ~3 Second Generation
Generates images in approximately 3 seconds — fast enough for interactive workflows, live previews, and high-volume production pipelines.
It depends on the job. Nano Banana Pro: Gemini Pro Image — 4K Output, 8 References, 64K Context. GPT Image 2: OpenAI's Next-Generation Image Model — Near-Perfect Text, 16 References, ~3s. Both are on The Factory on one credit balance, so you can run the same prompt on each and keep the better result.
