We’re in the middle of a series on LowEndBoxTV on the exploding world of AI companions. This market is huge and millions of people are using these applications and services. We’re going to give you a comprehensive overview, a deep dive into the tech, some problems and issues, the major options, and finally a DIY tutorial using SillyTavern. Enjoy!
SillyTavern is the premier DIY solution for AI Companion chatting. It’s free, open source, and incredibly flexible.
It also has a reputation for overwhelming new users. To coin a phrase, with great power comes great complexity. If you open it, you’ll see a maze of knobs, dials, switches, and sliders, but the good news is that you don’t need to mess with most of it.
In this tutorial, we walk through
- What SillyTavern is and how it works
- Installing the single pre-requisite, NodeJS
- Downloading and running SillyTavern
- Configuring the API
- Configuring up common options
- Setting up your Persona, System Prompt, and Character Card
- How to write (or borrow) a good System Prompt
- The art of writing a good Character Card
- How to see thinking/reasoning, use swipes, and more!
This is using SillyTavern from the perspective of a completely new user, so even if you have no experience with the product, you can go from download to up and running very quickly.
We’d love some feedback and comments on YouTube, and a sub if you’d be so kind.
