About Nano Banana 2
High-efficiency image generation and editing with faster iteration, precise text, and 1K, 2K, or 4K delivery.
Why choose Nano Banana 2?
Nano Banana 2 is Google’s Gemini 3.1 Flash Image model. It combines the high-throughput direction of the Flash family with stronger reasoning, text rendering, and editing control, making it a practical production tier between the original Nano Banana and Nano Banana Pro.
| Core strength | Best fit |
|---|---|
| High-efficiency generation | Production workflows that need speed without staying at the base model’s output tier |
| 1K, 2K, and 4K delivery | Draft, web, and high-resolution assets from one model key |
| Text and layout handling | Social graphics, product cards, diagrams, and campaign variations |
| Reference-guided editing | Preserve people, objects, or visual direction while changing selected details |
Prompting approach
Define the deliverable, subject, layout, exact text, palette, and output ratio. For edits, separate what must remain unchanged from the requested change. Use references with a single purpose each rather than adding images without a clear role.
Wizzx scope
The backend currently publishes separate 1K, 2K, and 4K price tiers. The model page may not expose every capability available in Google’s own API; follow the live Wizzx form and catalog.
