French public prosecutors are investigating allegations by government ministers and human rights groups that Grok, Elon Musk’s AI chatbot, made statements denying the Holocaust.

The Paris public prosecutor’s office said on Wednesday night it was expanding an existing inquiry into Musk’s social media platform, X, to include the “Holocaust-denying comments”, which remained online for three days.

Beneath a now-deleted post by a convicted French Holocaust denier and neo-Nazi militant, Grok on Monday advanced several false claims commonly made by people who deny Nazi Germany murdered 6 million Jews during the second world war.
