Chroma-Flash-Heun: Rank 64: chroma-flash-heun_r64-fp32.safetensors

Rank 64 can be used with very low CFG below 1.3 and will allow for significant reduction of step count depending on sampler/scheduler used. It can also be used without CFG (set to 1.0 in ComfyUI) at slightly higher step than with CFG.

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
