This series of LoRA models are extractions from chroma-unlocked-v47-flash-heun and despite the indicating name it is not restricted to be used with Heun sampler nor that lowest step is supported across all ranks.
I can't upload every model in one go so for any of the other ranks in the meantime, visit this huggingface model repo
Description
Rank 256 should be used without CFG (set to 1.0 in ComfyUI) and has significant reduction of step count depending on sampler/scheduler used. (8-16 for dpmpp_sde/heun/res_2s and 16-24 for euler/er_sde/res_multistep/res_2m etc.)
