# Grok Grok is [[xAI]]'s [[Large Language Models (LLMs)|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.
