Stable-fast compatibility with lightning models #146

Hi,

i am wondering if there is any known problems with using stable-fast on few-steps generation models such as SDXL Lightning? My experience is that stable-fast does not provide any speedup on sdxl lightning and its derivative models. Sometime it evens slow them down. I have not encountered similar issues with normal SDXL models before. Does anyone know a solution or work-around? Thanks!

Note: what's interesting is SDXL Turbo also works fine with stable-fast

@chengzeyi Hi, does this match with your experience/is this expected? Thanks
