The Flux.2 Dev workflow is designed to generate photorealistic images with a strong emphasis on multi-reference consistency and professional text rendering. This workflow leverages the Flux.2 Dev model, which is known for its ability to produce high-quality images by integrating multiple reference points to ensure consistency across different elements of the image. The use of quantized weights in this workflow allows for efficient processing without compromising the quality of the output. Key nodes such as SaveImage, ImageScaleToTotalPixels, and LoadImage are utilized to manage image inputs and outputs effectively, while the MarkdownNote node provides documentation and guidance within the workflow itself. This setup is particularly useful for users who need to create images that require precise text integration and consistency across multiple visual elements.
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.2 Dev" (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_flux2_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("46", "image", asset); // LoadImage
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.
