What SD sampler does the official Runway ML demo use?

What sampler does the official Runway ML demo use? https://runwayml-stable-diffusion-v1-5.hf.space/
I get much more creative results using this instead of A111 locally and I want to replicate it

hi @phok,
That Space is running with a custom jax/flax backend, it should be compatible thought
here an example code running there, using FlaxDPMSolverMultistepScheduler

Thanks. Which sampler would it most likely be from the A111 list? There are multiple. Also, in the app.js file, the settings are: samples = 4 steps = 50 scale = 7.5
