ComfyUI 的人脸替换工作流是一款为视觉特效艺术家设计的高级工具，用于在视频素材中实现变年轻或人脸替换。该工作流结合 AI 驱动的掩码、身份迁移和修复技术，实现跨帧自然一致的效果。关键节点如 WanVideoVAELoader 和 WanVideoModelLoader 用于加载和管理视频数据，DrawMaskOnImage 和 GrowMask 节点帮助精确绘制人脸掩码。还集成了 OnnxDetectionModelLoader 和 CLIPVisionLoader 等高级检测模型，准确识别和处理面部特征。通过这些组件的集成，确保新脸部与原素材无缝融合，保留光影和表演细节。
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.
