Grok is the LLM created by X.com (formerly Twitter). It has web search, image generation and PDF understanding capabilities. Due to its access to X.com live posts, Grok’s strength is knowledge of recent discussions, conversations, trends, and timely news.

The free version of Grok is available to all X users but comes with limitations on usage. Free users can only make 10 Grok queries every 2 hours and are restricted to 3 image generation queries per day.

X.com owner Elon Musk promotes Grok as being more open and less censored than other LLMs. This is because many popular LLMs will refuse to discuss sensitive or offensive topics. However, out of all the major online LLMs, Grok is known for actually responding to most questions and subject matter.
