This workflow upscales a single input image using the SeedVR2 model to produce a high-definition result with preserved edges and enhanced detail. It’s built around a simple path: LoadImage brings your source into the graph, the SeedVR2 upscaler node (custom node ID c35dd4ba-0fe3-47d6-afce-1c56d9fe5beb) performs super‑resolution, and SaveImage writes the upscaled output to your ComfyUI output directory. An optional ImageCompare node lets you preview a side‑by‑side before/after to verify gains in clarity.
Technically, the SeedVR2 node consumes the input image tensor and applies the SeedVR2 model’s learned upscaling to reconstruct higher‑frequency details at a larger resolution. Because this is deterministic super‑resolution (not text-to-image), results are driven by the source image’s content and quality rather than prompts. The included MarkdownNote inside the graph provides quick, inline guidance. Note that ImageCompare is available only under Nodes 2.0, so enable that mode if you want the built‑in A/B viewer.
API
通过代码使用此工作流
每个 Comfy 工作流都是一个 JSON 图。下面的内容就是此工作流的完整数据，ComfyUI 运行时也是如此——你可以从该 URL 获取、放入版本控制，或在 ComfyUI 中加载并逐节点运行。
使用 Comfy SDK 从 TypeScript 或 Python 运行。相同代码可用于 Comfy Cloud 或你自托管的 ComfyUI——只需更改基础 URL。
// 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");SDK 需要 API 格式的工作流：在 ComfyUI 中打开此工作流，使用 文件 → 导出工作流（API）。
