comfyanonymous ba9095e5bd Automatically use fp8 for diffusion model weights if:
Checkpoint contains weights in fp8.

There isn't enough memory to load the diffusion model in GPU vram.

Lower SAG scale step for finer control (#4158)
* Lower SAG step for finer control

Since the introduction of cfg++ which uses very low cfg value, a step of 0.1 in SAG might be too high for finer control. Even SAG of 0.1 can be too high when cfg is only 0.6, so I change the step to 0.01.

* Lower PAG step as well.

* Update nodes_sag.py

comfyanonymous eca962c6da Add FluxGuidance node.
This lets you adjust the guidance on the dev model which is a parameter
that is passed to the diffusion model.

comfyanonymous 66d35c07ce Improve artifacts on hydit, auraflow and SD3 on specific resolutions.
This breaks seeds for resolutions that are not a multiple of 16 in pixel
resolution by using circular padding instead of reflection padding but
should lower the amount of artifacts when doing img2img at those
resolutions.
