Hey Bae/Cogvideo anon, are you out there? I'd like to know what you (or anyone else who's interested) think of PyramidFlow. This is the first output I got from the 384p model but there is a 768p and 1024p model as well as CPU offloading. I don't have enough vram for the 768p model but it can go up to 10 seconds which is pretty dope.
