What do these numbers mean? rCM4.0 vs rCM6.0
I have question, I noticed there’s a new upload, and you deleted the old WAN i2v rCM. I also noticed the numbers changed, previously it was rCM6.0 High, and now it’s rCM4.0 high. What do those numbers actually mean?
Anyway, thank you for providing the alternative to Lightx2v!
We adopt model merging to get the Wan2.2 I2V rCM checkpoints from our 2.1 T2V rCM checkpoints. The merging operation is
[Wan2.2 I2V rCM w] = [Wan2.2 I2V base] + w * ([Wan2.1 T2V rCM] - [Wan2.1 T2V base])
4.0 and 6.0 are the w-value, similar to LoRA strength. After more testing, we found the newer high-4.0 and low-1.0 versions perform better.
We are happy that our models provide an alternative to Lightx2v. We have updated our codebase to provide an official inference script for Wan2.2 I2V rCM. There are some examples in https://github.com/NVlabs/rcm/blob/main/Wan.md.
Ah okay, Thanks for the explanation!
I’ll try it out soon, downloading now. Thank you!
