* should be here instead lol

* better settings

comfyanonymous 9f4daca9d9 Doesn't really make sense for cfg_pp sampler to call regular one. 2024-09-11 02:51:36 -04:00

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 2622c55aff Automatically use RF variant of dpmpp_2s_ancestral if RF model. 2024-08-18 00:47:25 -04:00
Ashen 1beb348ee2 dpmpp_2s_ancestral_RF for rectified flow (Flux, SD3 and Auraflow). 2024-08-18 00:33:30 -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 4f9d2b057c Remove print. 2024-06-27 02:54:15 -04:00
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.

comfyanonymous 57eea0efbb heunpp2 sampler. 2023-11-14 23:50:55 -05:00
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.
