This ComfyUI workflow is designed to upscale images by a factor of four using the Stability AI API, making it an ideal tool for enhancing low-quality or compressed images. The workflow leverages several key nodes to achieve this task efficiently. It begins with the 'LoadImage' node, which allows users to upload their desired image. Once the image is loaded, the 'StabilityUpscaleFastNode' processes the image using advanced algorithms provided by Stability AI, ensuring a high-quality upscale without loss of detail.
After upscaling, the 'ImageCompare' node is employed to juxtapose the original and upscaled images, offering a clear visual comparison of the improvements made. This node is accessible under the Nodes 2.0 menu, ensuring users have access to the latest tools for image analysis. Finally, the 'SaveImage' node allows users to easily save the enhanced image to their desired location. This workflow is particularly useful for photographers, graphic designers, and anyone needing to improve image quality quickly and effectively.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
