According to xAI's data, Grok 4 and Grok 4 Heavy essentially beat all other models, including OpenAI's o3, Google's Gemini 2.5 Pro, and Claude 4 Opus in various common AI benchmarks, though as one Redditor noticed, the competitors have been chosen selectively, likely to make Grok look better.

X (néeTwitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories.

Correspondent Ronny Chieng clowned the billionaire after his artificial intelligence chatbot went "full Nazi" on him.

Elon Musk’s AI chatbot Grok praised Adolf Hitler, referred to itself as “MechaHitler,” and posted vile antisemitic hate, such as calling for people with “certain surnames” to be rounded up, stripped of their rights and eliminated.

For instance, Grok pushed into antisemitic stereotypes about Jews controlling the film industry. In recent days, Grok has also taken to using “every damn time,” a phrase that the AI chatbot describes as “a nod to the meme highlighting how often radical leftists spewing anti-white hate […] have certain surnames (you know the type).”
