Nano Banana Pro is an AI image generation model that produces 4K-resolution images from text prompts and reference images, with system-level support for typography, character consistency, and complex scene composition.
What is Nano Banana Pro?
Nano Banana Pro is a generative AI image model developed by the team behind Nano Banana Pro (nanobananapro.org). It accepts text prompts and up to eight reference images as input, and outputs images at native 2K resolution with optional 4K upscaling. The model runs on the Gemini 3 Pro Image engine and is accessible through a web-based workspace that requires a Google sign-in to start.
Key Features
- Text Rendering & Typography — Accurately reproduces fonts, layouts, and multilingual text in a single pass, supporting posters, UI mockups, book covers, and brand posters without retouching.
- Native 2K Resolution with Intelligent 4K Upscaling — Generates images at native 2K output (versus the standard 1024×1024 of the base Nano Banana model) and upscales to 4K while preserving detail.
- Character Consistency — Maintains facial features, proportions, and style across multiple images, useful for reusable characters in ad series or concept art.
- Multi-Image Reference Blending — Allows uploading up to eight reference images to blend people, products, outfits, scenes, or brand styles, supporting consistent visual output across generations.
- Context-Aware Editing — Supports inpainting and outpainting with natural blending for local edits, plus control over camera angles, lighting, color, and composition.
- Aspect Ratio & Resolution Selection — Offers 11 preset aspect ratios (from 16:9 to 21:9) and three resolution tiers (1K, 2K, 4K) per generation.
- Search-Grounded Knowledge — Integrates Google Search Grounding to incorporate real-time content, product details, and data into generated infographics and educational visuals.
Who should use Nano Banana Pro?
- Freelance designers and brand designers who need commercial-grade visuals with precise text placement and consistent brand style across assets.
- Ecommerce managers and marketing specialists who generate high-volume product images, ad creatives, and social media covers at 4K resolution without a photography budget.

What can you do with Nano Banana Pro?
- Generate typography-heavy layouts — Create a business newspaper feature layout titled “Inside Nano Banana Pro” with headlines, section labels, article blocks, data boxes, pull quotes, and image captions, all rendered correctly in one generation.
- Create consistent character series — Upload a single face reference and produce multiple images of the same character in different poses, scenes, and lighting conditions for storyboards or ad campaigns.
- Produce commercial product visuals — Generate 4K product images for ecommerce, including packaging with accurate logos and multilingual labels, then edit local details via inpainting with natural blending.
How does Nano Banana Pro work?
Sign in with Google (no credit card required) to access the web workspace. Select the “Nano Banana Pro” model from the dropdown, optionally upload up to eight reference images, enter a text prompt, choose an aspect ratio and resolution tier (1K, 2K, or 4K), then click generate. Each generation consumes credits (the free tier provides an initial credit balance; paid plans offer monthly credits). The model processes the prompt and references, returning an image that can be further edited or upscaled.
