comfyanonymous 2a18e98ccf Refactor so that zsnr can be set in the sampling_settings. 2024-11-11 04:55:56 -05:00
comfyanonymous 56f3c660bf ModelSamplingFlux now takes a resolution and adjusts the shift with it.
If you want to sample Flux dev exactly how the reference code does use
the same resolution as your image in this node.

comfyanonymous 0eea47d580 Add ModelSamplingFlux to experiment with the shift value.
Default shift on Flux Schnell is 0.0

comfyanonymous 8e012043a9 Add a ModelSamplingAuraFlow node to change the shift value.
Set the default AuraFlow shift value to 1.73 (sqrt(3)).

comfyanonymous 7faa4507ec ModelSamplingDiscrete: x0 model support that predict a denoised image. 2024-02-21 08:05:43 -05:00
comfyanonymous 8b60d33bb7 Add ModelSamplingStableCascade to control the shift sampling parameter.
shift is 2.0 by default on Stage C and 1.0 by default on Stage B.

comfyanonymous adc40e3d7b Forgot this. 2023-12-15 15:46:23 -05:00
comfyanonymous 014c8bf2f2 Refactor LCM to support more model types. 2023-12-15 15:26:12 -05:00
comfyanonymous f30b992b18 .sigma and .timestep now return tensors on the same device as the input. 2023-11-27 16:41:33 -05:00
comfyanonymous 488de0b4df ModelSamplingDiscreteLCM -> ModelSamplingDiscreteDistilled 2023-11-27 16:32:03 -05:00
comfyanonymous 871cc20e13 Support SVD img2vid model. 2023-11-23 19:41:33 -05:00
comfyanonymous d9d8702d8d percent_to_sigma now returns a float instead of a tensor. 2023-11-18 23:20:29 -05:00
comfyanonymous dcec1047e6 Invert the start and end percentages in the code.
This doesn't affect how percentages behave in the frontend but breaks
things if you relied on them in the backend.

percent_to_sigma goes from 0 to 1.0 instead of 1.0 to 0 for less confusion.

Make percent 0 return an extremely large sigma and percent 1.0 return a
zero one to fix imprecision.

comfyanonymous ca2812bae0 Fix RescaleCFG for batch size > 1. 2023-11-10 22:05:25 -05:00
comfyanonymous 58d5d71a93 Working RescaleCFG node.
This was broken because of recent changes so I fixed it and moved it from
the experiments repo.

comfyanonymous 002aefa382 Support lcm models.
Use the "lcm" sampler to sample them, you also have to use the
ModelSamplingDiscrete node to set them as lcm models to use them properly.
2023-11-09 18:30:22 -05:00
comfyanonymous 844dbf97a7 Add: advanced->model->ModelSamplingDiscrete node.
This allows changing the sampling parameters of the model (eps or vpred)
or set the model to use zsnr.
