Notice
This workflow is not state of the art anymore, please refer to the Flux.1 Fill and the official comfyui workflows for your inpainting and outpainting needs. Details below:
Black forest labs has since released official flux 1 tools: https://blackforestlabs.ai/flux-1-tools/
The tools include the Flux.1 Fill [dev] model which is better than the alimama controlnet used in this workflow.
There is native comfyui support for the flux 1 tools: which you should use for your inpainting and outpainting needs.
AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Flux Inpaint and Outpaint Workflow is a ComfyUI workflow for inpainting and outpainting, using an image and mask information and providing image previews and saved images.
The graph includes LoadImage for an image, with ImageToMask and MaskComposite for mask handling.
PreviewImage and SaveImage are listed for image previews and saved images.
The instructions place FLUX.1-Turbo-Alpha.safetensors in models/loras/flux and FLUX.1-dev-Controlnet-Inpainting-Beta-fp8.safetensors in models/controlnet.
For a 16GB VRAM setup, the instructions say to rename diffusion_pytorch_model.safetensors and convert it to FP8 with Kijai’s script.
The listed model files are ae.safetensors; FLUX.1-dev-Controlnet-Inpainting-Beta-fp8.safetensors; FLUX.1-Turbo-Alpha.safetensors; flux1-dev-fp8-e4m3fn.safetensors; t5xxl_fp8_e4m3fn_scaled.safetensors; and ViT-L-14-BEST-smooth-GmP-TE-only-HF-format.safetensors.
The listed add-ons are ComfyUI-KJNodes and comfyui_segment_anything.
The author describes alimama-creative/FLUX.1-dev-Controlnet-Inpainting-Beta and alimama-creative/FLUX.1-Turbo-Alpha as the model pair for eight-step inpainting and outpainting in one workflow.
The author lists automatic segmentation as an option for systems with more than 16GB VRAM.
Before setup, verify the diffusion model filename: the instructions name flux1-dev-fp8-e4m3fb.safetensors, while the listed model file is flux1-dev-fp8-e4m3fn.safetensors.
Suggestion · not verified
The author says this workflow is no longer state of the art and will not be updated; for current inpainting or outpainting, they point to Flux.1 Fill and the official ComfyUI workflows.

You can grab the official comfyui inpaint and outpaint workflows from: https://comfyanonymous.github.io/ComfyUI_examples/flux/ by downloading the images (workflow embedded within the images) and opening them in comfyui.
If you have low VRAM, you can download the fp8 version of the Flux.1 Fill [dev] model from here: https://civitai.com/models/969431/flux-fill-fp8
This workflow will not be updated anymore because there is nothing I have to add to the official comfyui inpaint and outpaint workflows.
Introduction
The latest version of this workflow uses
alimama-creative/FLUX.1-dev-Controlnet-Inpainting-Beta
alimama-creative/FLUX.1-Turbo-Alpha
to achieve 8 steps inpainting and outpainting within the same workflow.
