The 'Flux.1 Dev OneReward' workflow is a versatile tool designed for image manipulation tasks such as inpainting, outpainting, and object removal. Developed by the bytedance-research team, this workflow leverages the Flux.1 model to seamlessly fill in or extend parts of an image. The workflow employs a series of nodes, including LoadImage, SaveImage, and PreviewImage, to manage the input and output processes. The core functionality is driven by nodes like cb0eaf1c-704f-477d-8893-79665db14ed1 and b8560576-5524-4495-baa5-2cb40da12e9e, which handle the complex computations required for high-quality image editing. This makes it particularly useful for creative professionals and enthusiasts who need precise control over image content.
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 "Flux.1 Dev OneReward" (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("image_flux.1_fill_dev_OneReward_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("17", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("62")[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.
