control-lora

like 798

From model card:
Rank 256 files (reducing the original 4.7GB ControlNet models down to ~738MB Control-LoRA models) and experimental
Rank 128 files (reducing to model down to ~377MB)

I think the question is how do those variations differ from each other in their use and output.

You need to try both and see how much 128 and 256 make difference to your specific use case as in result vs. resource usage
