This ComfyUI template builds a complete text-to-video pipeline around MiniMax H3 Max (Hailuo 03). At its core, MinimaxHailuo03TextToVideoNode turns your prompt from PrimitiveStringMultiline into a polished video, which is then written to disk by SaveVideo. SaveText also records the exact prompt that reached the generator so you can reproduce results later.
Two optional stages are wired behind ComfySwitchNode gates (visually marked in red) and controlled from the Feature Flags group. First, the Prompt Enhancer (Optional) can route your text through MinimaxHailuo03ContextIRNode before generation, producing a context IR object that the downstream node can use. Second, the Upscale Video to 2K (Optional) stage uses MinimaxHailuo03RegenerateNode to request a higher-resolution version of the same result. Important: the upscale stage only accepts a 768p source; set the base generator to 768p if you enable the Upscale to 2K boolean. This design lets you move quickly from idea to finished clip, then optionally refine fidelity and resolution without changing your base prompt.
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 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");The 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.
