HiDream Modular WF with Detail Daemon, LoRAs, Ultimate SD Upscale, FaceDetailer, img2img and Inpaint

UPDATE - May 19th, 2025 - As some of you are having trouble with LanPaint node, with ComfyUI-Essentials (by Cubiq aka Matteo, who is not working on ComfyUI any more unfortunately) and with LogicUtils custom nodes I am updating the workflow so it won't use these custom nodes. I hope to be able to update the wf and upload the new version next weekend. Since I am replacing the LanPaint node for inpainting, I am also changing the way Inpaint works, updating the workflow as suggested by @diogod by using "compositing" (I am testing the Inpaint Crop & Stitch nodes right now). So, stay tuned!

I made a new worklow for HiDream, and with this one I am getting incredible results. Even better than with Flux!

It's a txt2img workflow, with hires-fix, detail-daemon and Ultimate SD-Upscaler.

HiDream is very demanding, so you may need a very good GPU to run this workflow. I am testing it on an L40s (on MimicPC), as it would never run on my 16Gb VRAM card.

Also, it takes quite a bit to generate a single image (mostly because the upscaler), but the details are incredible and the images are much more realistic than Flux (no plastic skin, no flux-chin).

For v.1.0: You can also use GGUF model files, just replace the "Load Diffusion Model" node at the beginning of the WF with the "Unet Loader (GGUF)" node. See below:

In v.1.1 the two model-loader are both available, you can choose which one to use just selecting the standard model or the GGUF one in the "Model switch" node.

On my RTX 4070 Ti Super with 16Gb Vram I can run the workflow with the Q8 GGUF model file. Results are excellent!

HiDream E1 (image editing module) - for version 1.1

Just load an image and write what you would like to change in the positive prompt (you can also add a negative prompt). Due to model limitation, the image will always be resized and cropped to a 768x768 image (larger images will show a terrible lateral shift) and then resized to 1024x1024. It can't run in the Ultimate SD Upscaler, since the HiDream E1 model would overcook the image during upscale (so do not activate the Upscale Module!).

Results, for photo-realistic images are not that good, so do not expect any incredible output. But still, by using the right settings, you can achieve decent results.
