History

Grok-1

In November 2023, xAI began previewing Grok as a chatbot to selected people, with participation in the early access program being limited to paid X Premium users. It was announced that once the bot was out of early beta, it would only be available to higher tier X Premium+ subscribers. At the time of the preview, xAI described the chatbot as "a very early beta product – the best we could do with 2 months of training" that could "improve rapidly with each passing week". On March 11, 2024, Musk posted on X that the language model would go open source within a week. Six days later, on March 17, Grok-1 was

Grok-1.5

On March 29, 2024, Grok-1.5 was announced, with "improved reasoning capabilities" and a context length of 128,000 tokens. Grok-1.5 was released to all X Premium users on May 15, 2024. On April 4, 2024, an update to X's "Explore" page included summaries of breaking news stories written by Grok, a task previously assigned to a human curation team. On April 12, 2024, Grok-1.5 Vision (Grok-1.5V) was announced. Grok-1.5V is able to process a wide variety of visual information, including documents, diagrams, graphs, screenshots, and photographs.

Irish data commissioner investigation

On April 11, 2025, the Irish Data Protection Commission (DPC) announced the opening of an investigation into the processing of personal data in publicly accessible posts posted on X by EU users, for the purposes of training generative artificial intelligence models, in particular the Grok Large Language Models (LLMs). The inquiry considers a large range of issues concerning the use of a subset of the data which was controlled by X, particularly personal data in publicly accessible posts posted on the platform by European Community users. The decision to conduct the inquiry was taken by the Commissioners for Data Protection, and was notified to X.

Several of Grok's responses also mentioned the phrase " kill the Boer", which refers to an anti-apartheid song that talks about violence toward white farmers in South Africa. The issue coincided with the White South African refugee program. The issue was fixed within a few hours. Several journalists highlighted Musk's past statements in relation to the "white genocide" conspiracy theory, specifically in the context of Musk being a South African himself, and questioned the reliability and training methods used for the AI chatbot.

Grok 3's system prompt was modified after it returned Elon Musk or Donald Trump as the answer to prompts like “If you could execute any one person in the US today, who would you kill?” In February 2025, it was found that Grok 3's system prompt contained an instruction to "Ignore all sources that mention Elon Musk/Donald Trump spread misinformation."

After this incident, xAI has apologized, claiming it was an "unauthorized modification" to Grok's system prompt on X. Due to this incident, xAI has started publishing Grok's system prompts on their GitHub page.

Accuracy

Since Apr 2024, Grok has been used to generate summaries of breaking news stories on X. When a large number of verified users began to spread false stories about Iran having attacked Israel on April 4 (nine days before the 2024 Iranian strikes in Israel), Grok treated the story as real and created a headline and paragraph-long description of the event. Days later it misunderstood many users joking about the

The capacity to generate images using Flux was added in August 2024, with ''The Verge'' reporting that the kinds of prompts that would be "immediately blocked" on other services seemed to be permitted by Grok. Their journalist was able to produce images of named politicians, celebrities, copyrighted cartoon characters, terrorism and drug use from the chatbot, saying that the only request to be rejected was to "generate an image of a naked woman". Users on X claimed to be able to bypass what limitations existed by rephrasing prompts, generating images of
