comfyanonymous 6ab8cad22e Implement beta sampling scheduler. 
It is based on: https://arxiv.org/abs/2407.12173

Add "beta" to the list of schedulers and the BetaSamplingScheduler node.

Add sampler_pre_cfg_function (#3979) 
* Update samplers.py

* Update model_patcher.py
 2024-07-09 16:20:49 -04:00
comfyanonymous 05e831697a Switch to the real cfg++ method in the samplers. 
The old _pp ones will be updated automatically to the regular ones with 2x
the cfg.

My fault for not checking what the "_pp" samplers actually did.

comfyanonymous 44947e7ad4 Add DEIS order 3 sampler. 
Order 4 seems to give bad results.

comfyanonymous 69d710e40f Implement my alternative take on CFG++ as the euler_pp sampler. 
Add euler_ancestral_pp which is the ancestral version of euler with the
same modification.

Added a calc_cond_uncond_batch wrapper with a warning so custom nodes
won't break.

Implement Self-Attention Guidance (#2201) 
* First SAG test

* need to put extra options on the model instead of patcher

* no errors and results seem not-broken

* Use @ashen-uncensored formula, which works better!!!

* Fix a crash when using weird resolutions. Remove an unnecessary UNet call

* Improve comments, optimize memory in blur routine

* SAG works with sampler_cfg_function

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.

samplers.

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.
