looks like you’re doing everything right. I just tested it here on 2021.3.3 and managed to create a node using a hosted model, so not sure what’s going on on your side.
please note that some models seem to take a whiiiile to wake up, but even in that case you should be able to see the ML category and the node in the nodebrowser. the node might just display a warning saying the model is waking up.
if you have the file correctly placed and formatted and no nodes are showing up, did you double-check you correctly referenced VL.RunwayML in your patch by ticking the white box in the dependencies menu? this is the only issue that comes to my mind.
note that you don’t need an empty local-models.txt file if you don’t have local models to run.
@sebescudie, thank you for your reply. I’m also surpised it doesn’t work. Alkl seems correct but still after installing the nuget, placing the file in the right place and referencing the dipendecy I still don’t have the ML category! A mistery!
