If you can run 13B, I would recommend the following models. The links are for the GGML models. Keep in mind that if you can run a 30B or larger model, there are other LLMs that will work better.

This one is my personal current favorite. I think that it's better than Chronos for short messages. For me it usually sticks to using asterisks for actions, and quotes for speech, which is what I prefer.

This one feels more "clever" to me all around, and is currently very popular for roleplay. It produces results that are usually longer, so I feel like its better suited for longer dialogue. It also feels to me like it understands the scenarios better, and I usually get slightly more creative results from it.

If you’re looking for chatbots -

SillyTavern with turbo 3.5 is pretty good but you have to pay for the OAI API.

My experience with pygmalion wasn’t great but some really like it.

Character AI is unquestionably the best model and the easiest to use however it has a strict NSFW policy.

I’ve never tried llama but people did rave about it when it first released. I don’t know how easy it is to get up and running though.

It also really depends on VRAM IMO, I have a 4090 and these days I don't tend to touch anything under 30B (Wizard Uncensored is really good here) if I had dual 3090s I would likely be running a 65B model.
