# Nano Banana 2 Lite: Fast AI Image Generation

> Generate images at Google's fastest speed and lowest cost using Nano Banana 2 Lite, the Gemini 3.1 Flash-Lite Image model in ComfyUI

Nano Banana 2 Lite is Google DeepMind's fastest and most cost-efficient Gemini Image model, designed for rapid ideation and high-volume workflows. Powered by `gemini-3.1-flash-lite-image`, it delivers text-to-image generation in approximately 4 seconds at \$0.034 per image, making it ideal for quick concept visualization, rapid prototyping, and iterative design exploration.

      Make sure your ComfyUI is updated.

      * [Download ComfyUI](https://www.comfy.org/download)
      * [Update Guide](/installation/update_comfyui)

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated. (Desktop version's update will delay sometime)

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup
    </Tab>

    <Tab title="Desktop or Cloud users">
      * The Desktop is base on ComfyUI stable release, it will auto-update when there is a new Desktop stable release available.
      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

## Get started

1. Update ComfyUI to the latest version
2. Double-click the canvas and search for the "Nano Banana 2" node (it includes Nano Banana 2 Lite as a model option)
3. Or go to the Template Library to use the ready-to-go workflow
4. Select "Nano Banana 2 Lite" from the model dropdown for fastest generation

<Note>
  Nano Banana 2 Lite is available within the existing Nano Banana 2 node. If you have old workflows using this node, you can select "Nano Banana 2 Lite" from the model version dropdown without rebuilding your workflow.
