I put together a simple Flux GGUF version for the DreamO Image Customization workflow. Tested with as little as 6GB VRAM and includes the detail daemon sampler for extra sharpness and detail.

I have a video tutorial on how to set it up here -  https://youtu.be/1qJ8cE8NR-w

Also created a Runpod GPU Cloud Template for the Flux Dev FP8 model if more compute and higher quality is needed:
