Open source status

• The model implementation is available
• The model weights are available (Only relevant if addition is not a scheduler).

Provide useful links for the implementation

Hey @XXXKAY,

"DPM++ 2M Karras" corresponds to: https://huggingface.co/docs/diffusers/api/schedulers/multistep_dpm_solver
"DPM++ SDE Karras" is not yet supported see: #2064

[XXXKAY]

Thank you for your reply, and I am looking forward to "DPM++ SDE Karras".

Hey @XXXKAY,

"DPM++ 2M Karras" corresponds to: https://huggingface.co/docs/diffusers/api/schedulers/multistep_dpm_solver "DPM++ SDE Karras" is not yet supported see: #2064

How to switch between "DPM++ 2M" and "DPM++ 2M Karras" by using "DPMSolverMultistepScheduler"? I have tried but it seems like the default setting of "DPMSolverMultistepScheduler" is more like "DPM++ 2M". And I cannot find how to add the Karras.

My results:

"DPM++ 2M" by webui

"DPM++ 2M Karras" by webui

"DPMSolverMultistepScheduler" by diffusers

Seems like https://huggingface.co/docs/diffusers/api/schedulers/multistep_dpm_solver does correspond only to DPM++ 2M. DPM++ 2M Karras is not there yet. Am I correct, @patrickvonplaten ?

UPD: I see in the code that it's compatible with KarrasDiffusionSchedulers, how can one enable it? According to images above it's not enabled by default

[patrickvonplaten]

What's the difference between DPM++ 2M and DPM++ 2M Karras? Think only the sigmas are slightly different, but this shouldn't really change anything I think no? @zetyquickly do you see very differert results with DPM++ 2M and ... Karras?

[zetyquickly]

Not very different. If compare A1111 webui with diffusers side by side. The results of DPM++ 2M Karras (webui) will be different from DPM++ 2M (diffusers). At the same time DPM++ 2M (webui) will be almost identical with DPM++ 2M (diffusers).

In a message above there's three images with examples

Mine are DPM++ 2M (diffusers) vs DPM++ 2M (webui):

And DPM++ 2M Karras (webui)

From the perspective of quality it's arguably different, but from perspective of the highest reproducibility. It would be great to understand how to recreate DPM++ 2M Karras (webui) in diffusers

[patrickvonplaten]

Interesting thanks for the comparison here. For reproducibability I think we need to work on this issue: #1633

I currently don't find the time to work on it, but would be very happy to guide someone in case @zetyquickly you'd be interested :-)
