Builds and chats with personalized AI companions for engaging conversations

Chai AI

Chai AI, developed by CHAI RESEARCH CORP, is a pioneering platform aimed at advancing the interaction between users and social artificial intelligence.

Central to its innovation is the use of community-driven language learning models (LLMs) that collectively work towards creating an AI that surpasses the capabilities of individual LLMs. Critical efforts in their research include enhancing reward models, utilizing rejection sampling, and applying blending and reinforcement learning with human feedback.

This has led to significant advancements in AI’s ability to engage in meaningful interactions, with projects showcasing the positive impact of social AI on real-world engagement and the well-being of specific demographics, such as female young adults.

By compiling a proprietary dataset of over 4 billion user-bot messages and allocating over $16 million in compute resources, Chai AI is training language models optimized for entertainment and meaningful social interactions.

With over 500,000 ChatAI Creators, 4 million active users, and collaboration from over 100 foundational model developers – the platform boasts the deployment of over 10 trillion parameters and has served over 100 billion messages. This ecosystem is designed to foster the next generation of LLM platforms and espouse a more open and democratic approach to intelligent AI development.
