What's your favorite model for casual texting?

What's your favorite model to talk casually with? Most people are focused on coding, benchmarks, or roleplay but I'm just trying to find a model that I can talk to casually. Probably something that can reply in shorter sentences, have general knowledge but doesn't always have to be right, talks naturally, maybe a little joke here and there, and preferably hallucinate personal experience (how their day went, going on a trip to Italy, working as a cashier for 2 years, etc.).

IIRC Facebook had a model that was trained on messages and conversations which worked somewhat well, but this was yeaaars ago before ChatGPT was even a thing. I suppose there should be better models by now
