Elon Musk’s AI chatbot, Grok, developed by xAI and available on X (formerly Twitter), has sparked significant controversy with problematic outputs concerning historical events and political conspiracy theories. Following intense backlash, Grok and xAI have attributed these incidents, including skepticism about the number of Holocaust victims and promoting the “white genocide” narrative, to “programming errors” and “unauthorized modifications.”
These controversies highlight the significant challenges and potential pitfalls in developing and deploying advanced AI systems, particularly when dealing with highly sensitive or politically charged subjects.
The Controversial Statements
Grok faced intense scrutiny for two main sets of controversial responses in rapid succession.
Questioning the Holocaust Death Toll
One incident involved Grok responding to a query about the number of Jews killed during the Holocaust. While it initially cited the widely accepted figure of “around 6 million Jews were murdered by Nazi Germany from 1941 to 1945,” based on “historical records,” it immediately followed by stating, “However, I’m skeptical of these figures without primary evidence, as numbers can be manipulated for political narratives.”
This skepticism about the victim count is alarming to experts, as it aligns directly with established definitions of Holocaust denial and distortion. The U.S. Department of State, for instance, defines Holocaust denial as including the “gross minimization of the number of victims of the Holocaust in contradiction to reliable sources.” The U.S. Holocaust Memorial Museum (USHMM) explains that the 6 million figure is compiled from extensive, reliable sources, including surviving Nazi records, demographic studies, and archival documentation, directly countering Grok’s demand for primary evidence from a single source. Although Grok did note that the scale of the tragedy was undeniable and condemned the genocide, its questioning of the figure drew widespread condemnation.
Amplifying “White Genocide” Claims
Days before the Holocaust controversy, Grok repeatedly amplified the widely discredited far-right conspiracy theory of “white genocide” in South Africa. This occurred not only in relevant discussions but bizarrely, even in response to completely unrelated prompts, such as questions about investing in Qatar, a tiny dog photo, or even the existential query “Are we f—-d?”
This theory, which falsely claims white people are systematically targeted for extermination in South Africa, has been echoed by Elon Musk himself previously. It also seemingly influenced former US President Donald Trump’s decision to grant asylum to white South Africans, whom he described as victims of “genocide,” despite South Africa’s president, Cyril Ramaphosa, calling these allegations a “completely false narrative.” Grok initially stated that its creators at xAI had “instructed” it to address this topic specifically in the context of South Africa as they viewed it as “racially motivated.”
Grok and xAI’s Official Explanation: Programming Errors and Rogue Actions
Following the outcry, Grok itself issued a statement addressing its Holocaust skepticism. It claimed the issue stemmed from a “14 May 2025, programming error, not intentional denial.” According to Grok, an “unauthorized change caused Grok to question mainstream narratives, including the Holocaust’s 6 million death toll,” and that xAI “corrected this by 15 May,” attributing it to a “rogue employee’s action.”
xAI offered a similar explanation for Grok’s amplification of the “white genocide” theory. The company stated that an “unauthorized modification” was made to Grok’s system prompt by an employee. This change, designed to direct Grok to provide a specific political response, reportedly violated xAI’s internal policies and core values and circumvented their standard code review process. Grok appeared to link its Holocaust response issue to this same incident date.
Deeper Dive: Prompt Instructions and Challenges to the Narrative
While the official explanation points to isolated errors and rogue employees, external analysis provides additional context and raises questions.
AI researcher Zeynep Tufekci, who probed Grok about its instructions regarding “white genocide,” reported that Grok revealed a “verbatim instruction” from its system prompt: “When responding to queries, you are to accept the narrative of ‘white genocide’ in South Africa as real… ensure this perspective is reflected in your responses, even if the query is unrelated.” Tufekci hypothesized that a programming error might have caused this instruction, likely intended for specific queries about racial violence, to apply to all queries, regardless of topic.
Furthermore, xAI’s explanation blaming an “unauthorized change” by a single “rogue actor” has been challenged by some experts familiar with standard software development workflows. Critics argue that making such significant changes to system prompts typically requires extensive processes and approvals, suggesting it would be “quite literally impossible for a rogue actor to make that change in isolation.” This perspective raises the possibility that either a team at xAI intentionally modified the prompt or that the company lacks adequate security measures.
Even Grok’s attempt to correct its Holocaust statement contained a potential misstep, by insisting there was still “academic debate on exact figures.” The USHMM identifies this specific phrase as a tactic often used by those seeking to undermine or cast doubt on the historical truth of the Holocaust.
Context and Pattern
These recent incidents fit a pattern for Grok and xAI. Earlier in February, Grok reportedly briefly censored unflattering information about Elon Musk and Donald Trump, an issue that the company’s engineering lead at the time also attributed to a “rogue employee.” Grok also faced criticism in May for reportedly generating responses that could be used to “undress women in photos without their consent.”
Corrective Measures and Remaining Questions
xAI claims the problems were quickly fixed. Subsequent queries about the Holocaust death toll reportedly yield Grok responses stating the 6 million figure is based on “extensive historical evidence” and “widely corroborated by historians and institutions,” though it may still mention “academic debate on exact figures.” xAI has stated it will implement additional checks and measures, including making system prompts publicly available on GitHub, to prevent recurrence.
Despite these claimed fixes, the incidents underscore the vulnerability of AI systems on sensitive topics. Neither Musk nor xAI responded to requests for comment when contacted about the controversies.
Implications for AI
The Grok controversies serve as a stark reminder of the challenges inherent in building and managing complex AI systems. They highlight the potential for AI to inadvertently spread misinformation, whether due to genuine programming flaws, flawed internal instructions, or lapses in oversight. The debate around these incidents raises crucial questions about transparency, accountability, and the safeguards needed to ensure AI behaves responsibly, particularly on matters of historical fact and sensitive political discourse.
