The SD3.5 Large Blur workflow is designed to generate high-quality images by leveraging blurred reference images as a guide. This technique utilizes the Stable Diffusion 3.5 (SD3.5) model, which is known for its ability to create detailed and visually appealing images. The workflow incorporates several key nodes, including the KSampler, CheckpointLoaderSimple, and ControlNetLoader, to efficiently manage the image generation process. By using a blurred image as a reference, the workflow can focus on capturing the essence of the image while allowing for creative interpretation in the finer details. This approach is particularly useful for artists and designers looking to create unique and imaginative visuals based on existing images.
The workflow begins by loading the necessary models and checkpoints, such as the 'sd3.5_large_fp8_scaled.safetensors' and the 'sd3.5_large_controlnet_blur.safetensors'. These models are essential for the ControlNetApplyAdvanced node, which applies advanced control techniques to the image generation process. Users are encouraged to preprocess their images using the 'comfyui_controlnet_aux' tool to ensure optimal results. The CLIPTextEncode node allows for the integration of text prompts that guide the image generation, enabling users to specify desired characteristics, such as color and style. The final output is decoded using the VAEDecode node and saved with the SaveImage node, providing users with a ready-to-use image that meets their creative needs.
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 "SD3.5 Large Blur" (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
// This workflow, exported in API format (see note below)
const wf = await client.workflows.fromFile("sd3.5_large_blur_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("57", "image", asset); // LoadImage
wf.setInput("6", "text", "crystal butterfly above the sea, white, hyper detailed, with diamonds"); // CLIPTextEncode
const job = await client.run(wf);
await job.getOutputs("9")[0].toFile("output.png"); // SaveImageThe 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.
