At least Mozilla’s is opt-in by the sounds of it, runs entirely locally, and only with your own data that you consciously feed it.

If we’re being pragmatic, the cat is out of the bag now. “AI” is here to stay. And I’d rather use a privacy-respecting, locally-run instance that doesn’t send personally identifiable data, as opposed to using one from Google or Microsoft.

Mozilla’s at least used local AI so far, although it’s unclear whether they will stay on that route.

My opinion on LLMs is pretty much local only or no thanks 👍
