Ideal for: Background And Scene Swaps | Product Photo Refinement | Reference-Guided Edits

Google / Nano Banana 2 Lite Edit#


Nano Banana 2 Lite Edit is the cost- and speed-focused editing model in Google's Gemini image lineup. You upload one or more images, describe the change in words, and the model returns a revised 1K (1024x1024) picture, usually within a few seconds. Because it favors low latency over maximum resolution, it is built for high-volume, iterative editing rather than slow one-off renders.


On this RunComfy page you work with the editing side of the model. Send a prompt plus your source images, pick an aspect ratio, and receive the edited image URL in the standard prediction response. Multiple uploads can act as references, so the model has more context when applying a guided change.


Output format: Resolution: 1K (1024x1024) / fps: n/a / duration: n/a / aspect ratio: auto, 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16, 4:1, 1:4, 8:1, 1:8 / audio: n/a


Highlights#


  • Speed first: Nano Banana 2 Lite Edit targets a few-second turnaround, so tight revise-and-review loops stay practical.
  • Prompt-driven changes: Describe the edit in plain language, from a background swap to a lighting or color shift.
  • Multi-image input: Feed up to ten images to edit a source or to steer a result with references.
  • Low, flat cost: A single per-image rate keeps large editing batches easy to budget.
  • Flexible framing: Fifteen aspect-ratio options, including extreme cuts like 4:1 and 8:1, or leave it on auto to follow the input.

Frequently Asked Questions

What is Nano Banana 2 Lite Edit used for?

Nano Banana 2 Lite Edit is a fast, lightweight image editing model that reworks uploaded images from natural-language instructions. It is designed for prompt-based changes such as background swaps, style shifts, and object cleanup, returning a 1K edited image in the standard prediction response.

How is Nano Banana 2 Lite Edit different from the standard Nano Banana 2 Edit?

Nano Banana 2 Lite Edit is the speed- and cost-focused option, tuned for low latency at a fixed 1K resolution. The standard Nano Banana 2 Edit trades some speed for higher-resolution output options and stronger overall quality, so the Lite variant fits high-volume, iterative work where turnaround matters most.

Does Nano Banana 2 Lite Edit support multiple input images?

Yes. Nano Banana 2 Lite Edit accepts one or more uploaded images, up to ten, which can be edited directly or used as references to guide a result. Providing several images gives the model more context when applying a specific change.

What kinds of edits work best with Nano Banana 2 Lite Edit?

Nano Banana 2 Lite Edit handles background and scene swaps, lighting and mood changes, color and style adjustments, and product photo refinement well. For the most reliable results, state what should stay fixed and localize the change you want in the prompt.

What output resolution and aspect ratios does Nano Banana 2 Lite Edit produce?

Nano Banana 2 Lite Edit returns 1K (1024x1024) images and supports a range of aspect ratios, including common square, portrait, and landscape shapes plus extreme cuts like 4:1 and 8:1. Leaving the aspect ratio on auto lets the model follow the source image; check the RunComfy parameter panel for the full list.

What input limits should I know before using Nano Banana 2 Lite Edit?

A prompt and at least one source image are required, and up to ten images can be supplied. Output is fixed at 1K rather than higher resolutions, so if you need larger renders, consider a higher-tier model in the same family.

Can developers use Nano Banana 2 Lite Edit through the RunComfy API?

Yes. You can prototype Nano Banana 2 Lite Edit in the RunComfy model UI and then call the same model via the RunComfy API with identical parameters. This lets you move from manual testing to automated image editing without hosting or scaling the model yourself.

How much does it cost to generate with Nano Banana 2 Lite Edit on RunComfy?

Nano Banana 2 Lite Edit bills a flat $0.035 per output image at 1K, and aspect ratio does not change the price. Generations draw from your RunComfy usd or credit balance, and new users typically start with a free trial amount.
