# Schedulers

> Available schedulers for Pony models.

These are the available schedulers for Pony models.

## Quick lookup: Civitai / ComfyUI name → request fields

A `—` in the `algorithm_type` column means: omit the field, or send `no`.

Only the following diffusers schedulers honor `use_karras_sigmas=yes`:

* `DPMSolverMultistepScheduler`
* `DPMSolverSinglestepScheduler`
* `KDPM2DiscreteScheduler`
* `KDPM2AncestralDiscreteScheduler`
* `LMSDiscreteScheduler`
