![Flux.1 [Pro]: Text to Image](https://comfy-hub-assets.comfy.org/templates/10aa4ae1-1a97-4943-af02-d730a6ffb137.png)
The Flux.1 [Pro]: Text to Image workflow leverages the advanced capabilities of the Flux and Flux.1 models to produce high-quality images from text prompts. This workflow is designed to ensure excellent adherence to the provided prompts while maintaining superior visual quality. At its core, the workflow utilizes the FluxProUltraImageNode, which is responsible for interpreting the text input and generating corresponding images. This node is particularly effective in capturing intricate details and nuances described in the prompts. The workflow also includes nodes like SaveImage and LoadImage for managing input and output images, ensuring a seamless process from prompt to final image. Additionally, the MarkdownNote node is used to provide inline documentation and guidance within the workflow, making it easier for users to understand and follow the process.
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 [Pro]: Text to Image" (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("api_bfl_flux_pro_t2i_api.json");
const asset = client.assets.fromFile("input.png");
wf.setInput("14", "image", asset); // LoadImage
const job = await client.run(wf);
await job.getOutputs("12")[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.
