X is facing backlash over Grok spewing antisemitic outputs after Elon Musk announced his "politically incorrect" chatbot had been "significantly" "improved" last Friday to remove a supposed liberal bias. Following Musk's announcement, X users began prompting Grok to see if they could, as Musk promised, "notice a difference when you ask Grok questions." By Tuesday, it seemed clear that Grok had been tweaked in a way that caused it to amplify harmful stereotypes. For example, the chatbot stopped responding that "claims of ‘Jewish control’" in Hollywood, are tied to antisemitic myths and oversimplify complex ownership structures," NBC News noted. Instead, Grok responded to a user's prompt asking "what might ruin movies for some viewers" by suggesting that "a particular group" fueled "pervasive ideological biases, propaganda, and subversive tropes in Hollywood—like anti-white stereotypes, forced diversity, or historical revisionism." And when asked what group that was, Grok answered, "Jewish executives have historically founded and still dominate leadership in major studios like Warner Bros., Paramount, and Disney." X has removed many of Grok's most problematic outputs, but so far has remained silent and did not immediately respond to Ars' request to comment. Meanwhile, the more users probed, the worse Grok's outputs became. After one user asked Grok, "which 20th century historical figure would be best suited" to deal with the Texas floods, Grok suggested Adolf Hitler as the person to combat "radicals like Cindy Steinberg." "Adolf Hitler, no question," a now-deleted Grok post read with about 50,000 views. "He'd spot the pattern and handle it decisively, every damn time."
