# Topaz Image Enhance - AI image upscaling

> Upscale and enhance images with Topaz's generative models in ComfyUI: Wonder 3.5 for detail restoration and Bloom 2 for creative upscaling

Topaz Image Enhance is available in ComfyUI through the Topaz partner nodes. It provides two generative enhancement models: Wonder 3.5 and Bloom 2. Wonder 3.5 is a generative enhancement model that adds fine detail, reduces noise, and sharpens text and structured graphics, with low, medium, and high enhancement strengths. Bloom 2 is a creative upscaling model that adds new detail, texture, and visual elements, with a creativity control from 1 to 9 for subtle refinement or bold reinterpretation. Both models preserve the input aspect ratio and support upscale factors from 1x to 6x.

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

      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      If you can't find them in the template, your ComfyUI may be outdated.

      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 title="Cloud users">
      * [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.
