Grok Beta
Grok is xAI's witty assistant modeled on the Hitchhiker's Guide with real-time X data and a rebellious tone1. It tackles questions most models refuse and is still an early beta built in two months.
The Grok-1 engine powers the system using custom Kubernetes, Rust, and JAX infrastructure. It scored 73% on MMLU and 63.2% on HumanEval while early U.S. access remains waitlist only.
