GPT Image 2.5 Sunburst: Text to Image is a focused ComfyUI template that turns carefully structured prompts into polished, detail-rich images using OpenAI’s image generation API. The core of the workflow is OpenAIGPTImageNodeV2, which packages your prompt (using a "Sunburst" structure that calls out subject, materials, lighting, camera, and composition) and sends it to the selected OpenAI image model. The resulting image stream is then handed to SaveImage, which writes the outputs to your ComfyUI output directory.
Technically, the node exposes common OpenAI image parameters such as model, size/aspect, quality/style, number of outputs, and output format. The Sunburst prompt structure helps preserve subject identity, complex materials, lighting consistency, and scene layout by keeping a stable "anchor" block in your prompt across iterations. You iterate by adjusting only the variable parts (e.g., pose, background, or mood) while leaving the anchor descriptors unchanged—yielding high-fidelity refinements without rebuilding the entire scene each time.
API
Usa este flujo de trabajo desde código
Cada flujo de trabajo de Comfy es un grafo JSON. El siguiente payload es este flujo de trabajo, exactamente como lo ejecuta ComfyUI: descárgalo desde la URL, guárdalo en control de versiones o cárgalo en ComfyUI y ejecútalo nodo por nodo.
Ejecuta desde TypeScript o Python con el Comfy SDK. El mismo código funciona en Comfy Cloud o en un ComfyUI propio: solo cambia la URL base.
// 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");El SDK utiliza un flujo de trabajo en formato API: abre este flujo de trabajo en ComfyUI y usa Archivo → Exportar flujo de trabajo (API).
El acceso a la API de Comfy Cloud requiere un plan con clave API.
