diffusers no long use yaml config files, they use json configuration instead.

If only thing needed is to switch to v-prediction mode, you can do that in settings.

yes, but most models use default. The yaml file is mean to auto-switch to v-predication for models that request it.

True - and thats why I didn't close the issue, only noted the background.

Is there any tool in the UI itself to convert configs to json format? There is a python script floating around for converting safetensors to diffusers format, but I've never gotten it to work and load correctly.

not as far as I know, but shouldn't be too hard to write config converter - that's why I'm keeping this issue open - I'll take a look when I get back from my trip.
