The platform allows users to create, share, and interact with AI characters including celebrities, fictional characters, historical figures, animals, mentors, friends, and imaginary personalities without needing any coding skills.

The platform uses advanced conversational AI powered by in-house trained large language models, including 235B A22B Mixture-of-Experts models deployed in their production blend. Chai AI employs reinforcement learning techniques like RLHF, PPO, DPO, and GRPO optimized specifically for social engagement and entertainment purposes. The company serves over 500 million AI-generated messages per month with over 3.5 billion completions to date, operating on a 1.4 exaflops GPU cluster with 5000 GPUs serving 51K unique LLMs.
Key features include minimal content filtering allowing uncensored conversations including roleplay and story-driven chats, an image generation feature where AI creates images from prompts, instruction capabilities to adjust bot personalities/tone/storylines mid-chat, message editing, response regeneration, and social features like following/messaging other users. The app is available on iOS and Android with over 1 million daily active users.
Chai AI is designed for entertainment-focused users seeking engaging conversational AI experiences, roleplay enthusiasts, storytellers, fans of anime/RPG/horror/comfort characters, and power users who want uncensored AI interactions.
