Just testing some ideas with Flux :)For V4 pretty much as V3, 6-10 steps.For V3 use Euler Beta or Simple (DPM++ 2M SGM uniform seems fine too). 8-10 stepsThis is a Unet only, you need to add and load those <a target="_blank" rel="ugc" href="https://huggingface.co/lllyasviel/flux_text_encoders/tree/main">https://huggingface.co/lllyasviel/flux_text_encoders/tree/main</a>If you use Compfy UI this node works for NF4 <a target="_blank" rel="ugc" href="https://github.com/DenkingOfficial/ComfyUI_UNet_bitsandbytes_NF4">https://github.com/DenkingOfficial/ComfyUI_UNet_bitsandbytes_NF4</a>
