Add argument to explicitly enable fp8 compute support. (#8257)
This can be used to test if your current GPU/pytorch version supports fp8 matrix mult in combination with --fast or the fp8_e4m3fn_fast dtype.

Add experimental --async-offload lowvram weight offloading. (#7820)
This should speed up the lowvram mode a bit. It currently is only enabled when --async-offload is used but it will be enabled by default in the future if there are no problems.

Add option for using fp8_e8m0fnu for model weights. (#7733)

Add --use-flash-attention flag. (#7223)
* Add --use-flash-attention flag.
This is useful on AMD systems, as FA builds are still 10% faster than Pytorch cross-attention.

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.
