Chai AI
What is Chai AI?
Chai AI lets you create and talk to custom AI characters on mobile, with open-ended roleplay and personality-driven chat instead of factual Q&A. It launched on the App Store in February 2023, before Character AI and ChatGPT had consumer apps, and now serves over one million daily active users with average session times around 90 minutes.
Unlike general-purpose assistants optimized for factual answers, Chai trains hundreds of in-house language models for entertaining, personality-driven conversation. The team uses RLHF, model blending, DPO, and GRPO on user signals rather than textbook correctness, and their proprietary 10x24B blended ensemble reportedly beats GPT-4o on engagement by over 60%.
The company runs its own 1.4 exaflop GPU cluster with about 5,000 NVIDIA and AMD chips serving 1.2 trillion tokens per day across 51,000 unique LLMs. That infrastructure lets them AB test new architectures on live traffic instead of waiting on third-party API limits.
Chai fits mobile users who want open-ended roleplay, creative writing partners, or casual character chat. Browse community-made personalities or build your own from scratch on iOS and Android.
