Grok

Grok is a family of AI models and an API from xAI for building chat assistants that can call tools and optionally use live search to include current information from the web and X.

Developers access Grok through a REST chat-completions interface that supports prompting and function calling to integrate external tools. Live search is disabled by default and can be enabled per request with configurable sources such as web, news, and X. xAI has also released the Grok-1 base model weights and architecture under the Apache 2.0 license for local experimentation outside the hosted API.
