About Chai Research

Social and Conversational AI at Scale

Chai Research is an AI platform based in Palo Alto, focused on advancing conversational generative AI. With over 1.5 million daily active users and $20M in revenue, Chai empowers anyone to create, interact with, and share intelligent agents designed for entertainment, engagement, and communication.

A Platform for Builders and Creators

Chai is built around the belief that AI should be not just accurate, but engaging and humanlike. Unlike purely factual assistants, Chai’s LLMs are tuned for social interaction—making them ideal for storytelling, roleplay, and interactive dialogue that feels alive.

What Makes Chai Unique

Built for Creator-Led AI

Chai allows developers and content creators to build and share their own conversational agents. The platform’s scale and user base enable creators to get instant feedback, iterate quickly, and grow an audience—all within an ecosystem designed for high engagement.

Research-Driven Development

The Chai team continuously experiments with advanced training methods including:

• RLHF (Reinforcement Learning with Human Feedback)
• LoRA (Low-Rank Adaptation)
• SFT (Supervised Fine-Tuning)
• Prompt Engineering & Routing

These methods are used to steer models toward more aligned, safe, and dynamic outputs—optimized for user enjoyment and creator intent.

Key Features and Capabilities

Feedback Loops for Quality

With millions of conversations per day, Chai is able to collect valuable user data that improves model performance through real-world feedback. The platform helps surface the best AI agents, fueling a creator economy around conversational AI.
