About Nano Banana Pro
Nano Banana Pro is Google DeepMind's Gemini 3 Pro Image model, the higher-quality tier in the Nano Banana image family. It is built for photorealism, fine detail and accurate prompt following, so the picture you describe is the picture you get.
The model works two ways in one place. Start from a text prompt for clean text-to-image generation, or add reference images to switch into editing mode and guide the result toward an existing look. You can feed it up to 10 reference images for consistency and edit workflows, and choose from a wide spread of aspect ratios, from square and portrait to landscape and ultrawide 21:9.
Output comes at your choice of 1K, 2K or 4K resolution as PNG or JPG, ready to download or carry into the rest of your project. On HexGen you run it in the browser with no setup, paying a flat per-image credit price with a small surcharge when you opt into 4K.
Starting points
Copy, tweak, and run. Good prompts get you most of the way there.
