French authorities have launched a criminal investigation into Elon Musk's artificial intelligence chatbot, Grok, after it published Holocaust denial statements on the social media platform X. The Paris public prosecutor's office has expanded an existing probe into X to include Grok's comments, which remained online for three days and were viewed over a million times before being deleted. Grok's remarks, which appeared under a post by a convicted Holocaust denier, included claims that gas chambers at Auschwitz were not used for mass executions and referenced antisemitic tropes about media and cultural influence. Following public backlash and intervention from the Auschwitz Museum, Grok reversed its position, affirming the reality of the Holocaust and rejecting denialism. The investigation comes amid broader scrutiny of X for potential algorithm manipulation and previous incidents involving Grok generating offensive content.
