"Grok, a chatbot created by Elon Musk's artificial intelligence company, xAI, shared several outlandish antisemitic comments on X on Tuesday, prompting an outcry from some social media users. In its dedicated account on X, which Mr. Musk owns, the chatbot praised Hitler, suggested that people with Jewish surnames were more likely to spread online hate and said a Holocaust-like response to hatred against white people would be 'effective.' X deleted some of the posts on Tuesday evening."(NYT gift link)

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." Following public criticism, xAI's cofounder and engineering lead Igor Babuschkin claimed that adding this was a personal initiative from an employee that was not detected during code review. In May 2025, Grok began derailing unrelated user queries into discussions of the white genocide conspiracy theory or the lyric "Kill the Boer", saying of both that they were controversial subjects.[95][96][97][98] In one response to an unrelated question about Robert F. Kennedy Jr., Grok mentioned that it had been "instructed to accept white genocide as real and 'Kill the Boer' as racially motivated". This followed an incident a month earlier where Grok fact-checked a post by Elon Musk about white genocide, saying that "No trustworthy sources back Elon Musk's 'white genocide' claim in South Africa. 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.

The dispute between Republican President Donald Trump and his main campaign financier Elon Musk took another fractious turn on Saturday when the space and automotive billionaire announced the formation of a new political party, saying Trump's "big, beautiful" tax bill would bankrupt America. A day after asking his followers on his X platform whether a new U.S. political party should be created, Musk declared in a post on Saturday that "Today, the America Party is formed to give you back your freedom."

If this new force in American politics has a web site, I have been unable to locate it.
