# Nano Banana 2 - Fast AI Image Generation

> Generate high-quality images with Pro-level quality at Flash speed using Nano Banana 2 in ComfyUI

Nano Banana 2 is now available in ComfyUI through Partner Nodes. This release fundamentally changes the default choice for most creators, delivering Pro-level quality at Flash speed.

<Tip>
  To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the [API Nodes Overview](/tutorials/partner-nodes/overview) section of the documentation to understand the specific requirements for using the API nodes.

    <Tab title="Portable or self deployed users">
      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      If you can't find them in the template, your ComfyUI may be outdated.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.

## What's new in Nano Banana 2

* **Pro-level quality at Flash speed** — Richer textures, sharper detail, stronger lighting, and better prompt adherence without the latency tradeoff
* **Search-grounded world knowledge** — Intelligently triggers Google Image Search grounding to improve factual accuracy for lesser-known landmarks, niche objects, or real-world details
* **Subject consistency** — Maintain character resemblance of up to 5 characters and fidelity of up to 14 objects in a single workflow
* **Configurable thinking levels** — Control how much the model "thinks" before generating (Minimal for fast exploration, High/Dynamic for complex layouts)
* **Precision text rendering and translation** — Generate accurate, legible text for marketing mockups, greeting cards, and localized assets

## Which model should you pick?

| Model               | Best for                                                                                |
| ------------------- | --------------------------------------------------------------------------------------- |
| **Nano Banana 2**   | Most creators — fast enough to explore, smart enough to refine, polished enough to ship |
| **Nano Banana Pro** | Maximum factual precision and high-stakes edge cases                                    |

## Get started

1. Update ComfyUI to the latest version
2. Double-click the canvas and search for the "Nano Banana 2" node
3. Or go to the Template Library to use the ready-to-go workflow
4. Choose your resolution, set your aspect ratio, and decide whether the prompt needs deeper reasoning

<Note>
  The new model version has also been added to the previous "Nano Banana Pro" node. If you have old workflows with this node, you don't need to rebuild them — just reselect the model version.
