Nano Banana 2 AI Image Generator
What is Nano Banana 2?
Nano Banana is Google's Gemini image model for generating and editing images. On top of text-to-image, it takes up to 14 reference photos so you can edit, combine, and transfer style in a single run, which is where it pulls ahead of a plain prompt box. Polishing one clean shot and merging several photos into one composition are both in scope, and prompts can run up to 20,000 characters when a scene needs detail. Output comes at 1K, 2K, or 4K in PNG or JPEG. On Kavel, Nano Banana runs through the KIE runtime, the credit estimate updates before you commit, and failed generations are never charged. Because generation, editing, and compositing share one screen and one credit meter, a job that would normally cross a generator, an editor, and an upscaler stays in one place from first draft to final frame.
Text-to-image generates a picture from a written description alone, with prompts up to 20,000 characters for detailed scenes.
Image-to-image edits and combines up to 14 reference photos, so composites and style transfer happen in one run.
Output at 1K, 2K, or 4K lets you draft cheaply and then finish at the resolution the job needs.

From input to output
Choose an input method, set resolution, aspect ratio, and photo count, and the credit estimate updates before you generate.
What the model can make
Generate from text, or edit and combine from photos. These are real output examples, from a single generated subject to a multi-photo composite. Each example below started from a plain prompt or a handful of reference photos, so you can judge the kind of result to expect before you spend a single credit.

When Nano Banana is the right pick
Reach for it when you want more than one clean shot: when several photos need to become one composition, and when references should steer the result. A lighter Lite variant keeps quick drafts cheap while the full model handles the final, high-resolution frame. In practice that means fewer tools to learn, one bill to watch, and a faster path from a rough idea to a frame you can actually ship, whether you are polishing a single portrait or assembling a product scene from several source photos.
Handle many photos at once
Up to 14 reference photos means composites and style transfer that a single image cannot do finish in one generation.
Lite to draft, full model to finish
Draft with the lighter Lite variant (1K about 5 credits), then switch to the full model (1K about 8 credits) for quality and higher resolution.
No surprise bills
The estimate for your resolution and photo count shows before you generate, and failed generations cost nothing.
