Add CFG++ to DPM++ 2S Ancestral (#3871)
* Update sampling.py

* Update samplers.py

* my bad

* "fix" the sampler

* Update samplers.py

* i named it wrong

* minor sampling improvements

mainly using a dynamic rho value (hey this sounds a lot like smea!!!)

* revert rho change

rho? r? its just 1/2

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.
2024-06-26 22:40:05 -04:00
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.

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
