CHAI

Long-context models, LoRA and RLHF are the techniques CHAI says it experiments with to match AI behavior to what a content creator intends.

CHAI is a chatbot and virtual companion platform for conversational generative AI, where ordinary people build AI characters and content they can talk to and share with others.

The company also lists SFT, prompt engineering, rejection sampling and LLM routing among the proven methods it applies in practice, so the focus is on applying established tuning approaches rather than inventing new ones.

Scale is the main selling point.

CHAI reports more than 1.5M daily active users and $20M in revenue, which suggests a large community of characters to chat with.

It is a paid product, with pricing starting at $20.

Beyond character chat, it is also tagged for writing and editing and general productivity use, though conversation with user-made AI is clearly the core.

If you want to create and share your own chatbot personalities, CHAI is built around exactly that.
