If author runs the local model for privacy reasons, then I don't understand why they give Telegram access to all their conversations. It's well known that Telegram doesn't end-to-end encrypt bot accounts.
The beauty of this is that you can just swap out the platform and everything remains as it's the same backend. You make a really good point, one that I haven't really considered, but I also only have so many hours in the day to be fiddling around with stuff.
I think I'd use Discord instead. Clankers are happy to set it all up for you.
Discord is even worse than Telegram in the privacy aspect though!?
Depends what actors you trust. They are equally bad but personally I‘m way more comfortable with the Discord story.
