Tech billionaire Elon Musk's artificial intelligence firm xAI issued a lengthy public apology via Grok's official X account on Saturday for the antisemitic remarks made by the chatbot earlier this week. The company blamed a system update for the use of violent language, saying that the root cause was an update to a code path upstream of the bot.

The tech billionaire unveiled its latest version, Grok 4, which he claims is "smarter than almost all graduate students, in all disciplines, simultaneously."
