All in one WAN 2.2 model merges: 4-steps, 1 CFG, 1 model speeeeed (both T2V and I2V)

I made up some WAN 2.2 merges with the following goals:

• WAN 2.2 features (including “high” and “low” models)
• 1 model
• Simplicity by including VAE and CLIP
• Accelerators to allow 4-step, 1 CFG sampling
• WAN 2.1 lora compatibility

… and I think I got something working kinda nicely.

Basically, the models include the “high” and “low” WAN 2.2 models for the first and middle blocks, then WAN 2.1 output blocks. I layer in Lightx2v and PUSA loras for distillation/speed, which allows for 1 CFG @ 4 steps.

Highly recommend sa_solver and beta scheduler. You can use the native “load checkpoint” node.

If you’ve got the hardware, I’m sure you are better off running both big models, but for speed and simplicity… this is at least what I was looking for!
