Source description

This workflow is what I use to save metadata to my images with ComfyUI. It requires a few custom nodes, including ComfyUI Essentials and my own Flux Prompt Saver node.

If the nodes appear red in the graph, it means you do not have the custom nodes installed. Please check out ComfyUI Manager for the best way to manage custom node installation.

Note that this node does require you to manually select the checkpoint and will not capture additional networks (LoRAs). It captures the prompt and basic information like the sampler, steps, seed, size, etc. This takes advantage of the Flux Sampler Parameters node from Essentials which replaces the standard Ksampler or SamplerCustomAdvanced.

Please feel free to leave questions in the comments, but comments like "it doesn't work" are not constructive and don't give me enough information to help you troubleshoot. I highly recommend you instead join my Discord at

AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

Use this ComfyUI workflow to save generation metadata to images. It takes a manually selected checkpoint and captures the prompt, sampler, steps, seed, size, and other basic generation settings.

Flow

The workflow uses Flux Sampler Parameters from ComfyUI Essentials instead of the standard Ksampler or SamplerCustomAdvanced.
The workflow file is FluxMetadataV1.json and contains 13 nodes.

Inputs and outputs

Select the checkpoint yourself; additional networks such as LoRAs are not captured.

Setup

Setup requires custom nodes, including ComfyUI Essentials and Flux Prompt Saver.
Nodes shown in red in ComfyUI indicate that the corresponding custom nodes are not installed; ComfyUI Manager is suggested for installation.

Dependencies

Node types listed include CheckpointLoaderSimple, CLIPTextEncode, CR Integer To String, CR Seed, and EmptySD3LatentImage.
They also include FluxPromptSaver, FluxSamplerParams+, LoraLoaderModelOnly, String Literal, and VAEDecode.
Listed model files include flux1-dev-fp8.safetensors, AndroFlux-v19.safetensors, mjv6_lora flux.safetensors, Valorant_Style.safetensors, and XLabsRealism.safetensors.

Configuration

It is version v1 and uses Flux.1 D as its base model.
The title is Flux Metadata for ComfyUI Workflow — v1, published by NuxSinistra.
It is a workflow, so a Pipe version does not apply.

Cautions

Before installing node packages, verify which packages provide VAEDecode, EmptySD3LatentImage, CheckpointLoaderSimple, CLIPTextEncode, and LoraLoaderModelOnly.
