Big ASP v2 is an incredible feat, but it's a bit unstable and needs some merging to get the best out of it.
I've been doing extensive testing of merging various checkpoints with various recipes and will upload the best results here.
Usage guide
Please refer to this workflow:

Note like all bigASP based models it's a bit unstable and sensitive to parameters. stick closely to the below.
Sampling
PAG ( Perturbed attention guidance ) around 1.8 is a must. This is only implemented properly in ComfyUI and SwarmUI unfortunately
CFG: 2 to 3 ( I recommend 2.5-2.8 )
55 steps
DPMPP 2M SDE sampler
Karras scheduler
Use DMD2 lora for upscaling ( see workflow link

waiting for 4 step lightning version
dont need to. just follow his example workflow and use the dmd2 lora. dmd2 is better than lightning
This is a great merge, not just of ASP, but in general. It finds an amazing middle-ground without being the same every time.
