3/3/26 UPDATE
I've uploaded a custom merge of the 2603 2-step lora and my key edit of the 2602 8-step lora. This has resulted in a nice, flexible distill that can generate great outputs from 4-10 steps. It has also helped the gridmarking artifacts that were visible at 1.0 strength with the 8-step 2602 UDCAI Edit lora. Please check it out!
Original Post
Credit to alibaba-pai for their fantastic work! This is a step and cfg distill lora to be applied to Z-Image base model and its derivatives. The lora has been converted to be compatible for use in ComfyUI.
Best run at 8 steps with CFG 1. Avoid sageattention. Samplers that add noise per step such as LCM or dpmpp_SDE seem to work well.
Description
This is an edited lora from the official one uploaded by alibaba-pai.
There were additional keys in the official 2602 8-step lora that affected many samplers/schedulers, due to not converging properly when sigmas are <0.500. My edit removes a number of these keys to allow for the lora to function with all samplers/schedulers while maintaining many of the key improvements.
