Running a local LLM - downloading LM studio, installing on Windows, using the search function to search for a popular LLM, click "download", click the button to load the model, chat.

Fine-tuning - obtaining a dataset for your task (this in itself is not trivial), figuring out how the service you linked works (after figuring out that it exists at all), uploading the dataset, paying, downloading the weights - OK, now how do you load them into LM studio?

It's all subjective, of course, but for me there's a considerable difficulty jump there.
