Use enum list for --fast options (#7024) 2025-03-01 02:37:35 -05:00
comfyanonymous
cf0b549d48 --fast now takes a number as argument to indicate how fast you want it. 
The idea is that you can indicate how much quality vs speed you want.

At the moment:

--fast 2 enables fp16 accumulation if your pytorch supports it.
--fast 5 enables fp8 matrix mult on fp8 models and the optimization above.

--fast without a number enables all optimizations.
