After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

On Sunday, the chatbot was updated to "not shy away from making claims which are politically incorrect, as long as they are well substantiated." By Tuesday, it was praising Hitler.

Grok will be available in Tesla vehicles, the company’s CEO Elon Musk announced on his social media platform X on Thursday morning—hours after xAI launched Grok 4, the most recent version of the chatbot that sparked controversy earlier this week after posting in what it called “MechaHitler mode.”
