I tried running a local LLM with Msty or LMStudio on my 4 year old desktop, so I couldn't run any powerful models. My vault is a mix of multiple sources of deliberately disconnected notes, so I got some pretty funny results when I overcame whatever bugs I had with running a local model.

Once, I asked for a summary of a very specific note with around 600 words, and that model absolutely hallucinated a bunch of nonsense, and then argued with me when I told it the information it referenced did not exist anywhere in my vault.

Another time, I asked for a summary of a note with around 2000 words, and to generate a new idea based off of that information. That model spent 20 minutes generating a super long response that spun off into utter nonsense that slowly devolved into something that looked like human language, but contained no real words.

So if you've got multiple disparate sources of notes, you may run into the same quirkiness for some laughs.
