Grok

Canonical version: Grok.

Grok is xAI's Large Language Model (LLM). Grok is multi-modal. It can generate text, images, etc. It's deeply integrated in the X platform. Users can ask Grok to analyze tweets/threads and to generate content by using @grok ....

Outside X

Since May 2026, a Grok / SuperGrok subscription can be used as an agent backend inside Hermes Agent via OAuth (no API key); the same subscription exposes Grok 4.3, Grok TTS, and Grok Imagine. xAI is treating the consumer subscription itself as the credential for third-party agents.
