What exactly is being compared in this workflow?

The workflow compares the original image (from LoadImage) with the edited image generated by GeminiNanoBanana2V2. ImageCompare places them side-by-side for visual assessment; no numeric metrics are computed.

How do I ensure a fair, readable comparison?

Keep the source image constant and change only the edit instruction or a single parameter at a time. Use consistent output size, and review the same regions (faces, edges, text) for drift or artifacts.

When should I choose Nano Banana 2 Lite for edits?

Choose it when you need fast, coherent edits to an existing image—such as color tweaks, lighting adjustments, or minor object-level changes—where turnaround speed is important.

Why does the edit sometimes alter areas I didn’t mention?

Under-specified instructions can lead to broader changes. Make your intent explicit (what to change and what to keep), and iterate with more targeted guidance to reduce unintended drift.

Nano Banana 2 Lite：图像编辑

本对比工作流展示 Nano Banana 2 Lite（通过 GeminiNanoBanana2V2 节点）如何根据你的编辑指令将源图像转变为新图，并以 ImageCompare 并排显示原图与结果，便于快速判断变化与一致性。

流程受控：两侧均源自同一张原图（LoadImage），仅模型编辑不同。这样便于评估速度与保真度、风格偏移程度、结构或身份保持情况。Nano Banana 2 Lite 注重响应速度和高效编辑，适合常见任务（如色彩调整、小物体增删），如需复杂或大范围变换，建议精细指令或多次迭代。

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）。

Comfy Cloud API 访问需要包含 API 密钥的套餐。
