Fix memory leak by properly detaching model finalizer (#9979)
When unloading models in load_models_gpu(), the model finalizer was not
being explicitly detached, leading to a memory leak. This caused
linear memory consumption increase over time as models are repeatedly
loaded and unloaded.

This change prevents orphaned finalizer references from accumulating in
memory during model switching operations.

Support for Qwen Diffsynth Controlnets canny and depth. (#9465)
These are not real controlnets but actually a patch on the model so they
will be treated as such.

Put them in the models/model_patches/ folder.

Use the new ModelPatchLoader and QwenImageDiffsynthControlnet nodes.

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.
