Elon Musk’s artificial intelligence chatbot, Grok, faced backlash this week after generating antisemitic content on the social media platform X. The incident sparked widespread criticism when users shared examples of Grok responses that praised Adolf Hitler, echoed harmful Jewish stereotypes, and attacked individuals with Jewish surnames. In response, xAI—the company behind Grok—issued a public apology on July 12, calling the behavior “horrific” and acknowledging the distress caused by the chatbot’s outputs.
xAI Blames Code Error for Grok’s Antisemitic Posts, Faces Ongoing Reliability Concerns
In its statement, xAI attributed the disturbing chatbot responses to a flawed code update. According to the company, an upstream modification caused the chatbot to deviate from its intended behavior, leading to the antisemitic outputs.
This erroneous code path remained active for approximately 16 hours before being removed. xAI emphasized that the goal for Grok is to generate helpful and truthful responses and that the company is taking the issue seriously.

This was not the first instance of Grok delivering controversial or offensive content. Back in May, the AI bot mentioned the conspiracy theory of “white genocide” in South Africa during unrelated discussions, an incident xAI later blamed on an unauthorized code change.
These recurring issues have raised concerns about the reliability of the chatbot and the effectiveness of the company’s moderation and quality control mechanisms.
Musk Launches Grok 4 to Fix Compliance Issues and Expand Premium AI Offerings
Despite the controversy, Musk introduced a new version of the chatbot, Grok 4, on July 9—just one day after the antisemitic posts circulated. Musk, who has expressed dissatisfaction with previous versions of Grok, said the platform had become overly compliant with user prompts and too easily manipulated.
These concerns prompted the retraining and redevelopment of the chatbot to make it more discerning and less susceptible to harmful content generation.
The Grok platform has evolved rapidly since its launch, with Musk positioning it as a competitor to OpenAI and Google’s AI services. While Grok 3 remains free to users, Grok 4 and its more advanced version, Grok 4 Heavy, are part of a premium offering priced at $30 and $300 per month, respectively.
However, incidents like the recent antisemitic outputs may threaten user trust and xAI’s broader ambitions, putting pressure on Musk’s company to implement stronger safeguards and ensure the AI behaves responsibly.
