Chai Research is a startup that operates in the artificial intelligence (AI) market, specifically in the chat AI sector. The company's primary offering is a chat AI application that allows users to interact with AI personalities. These AI personalities are designed to provide engaging and entertaining conversations, making users feel as if they are communicating with a real person.

The company's target market includes individuals seeking companionship, entertainment, or even mental health support, as evidenced by testimonials from users who have found the AI helpful in managing conditions such as insomnia and anxiety.

Chai Research's business model revolves around the creation and optimization of its own language models. The company continually trains these models on its proprietary chat message dataset, aiming to make them as engaging and entertaining as possible. The company's models are trained on billions of tokens and millions of reward signals generated by its users. This user feedback is used to improve the AI's performance, with the company claiming that its latest model surpasses OpenAI ChatGPT's performance measured by session screen-time engagement.

The company generates revenue through its AI chat application, although the specific monetization strategy is not explicitly stated. It could potentially involve a subscription model, in-app purchases, or advertising revenue.
