#### Eta parameter

TODO
|

The eta parameter only applies to the DDIM scheduler, and can introduce additional noise over time, leading to
|
||||
somewhat unpredictable images.

From [the HuggingFace docs](https://huggingface.co/docs/diffusers/api/pipelines/ddim):

> The eta parameter which controls the scale of the variance (0 is DDIM and 1 is one type of DDPM).

|

In general, a higher eta parameter will require more [steps](#steps-parameter) to produce a similar quality result.

longer to run.

The Euler Ancestral scheduler can usually produce decent results in 30-45 steps, while some of the others need 80-100 or

more. Inpainting may need more steps, up to 120 or 150 in some cases. Using too many steps can increase the contrast

#### Correction order parameter

TODO

Whether to run correction before upscaling, after upscaling, or both.
|

|

Running correction before upscaling can remove noise and improve faces so that the upscaling model has a better input
|
||||
image to work with, while running correction after upscaling can help remove noise and artifacts introduced by the
|
||||
upscaling model. Using both will address both issues, but typically needs a lower [correction

strength](#correction-strength-parameter).
