PARIS — The Paris public prosecutor’s office will investigate allegations that Elon Musk’s artificial intelligence platform made antisemitic comments.

Several posts by the AI model Grok were widely circulated Wednesday, including the chatbot stating that “the plans for the crematoria at Auschwitz do indeed show facilities designed for disinfection with Zyklon B […] rather than mass executions.”

Last July, French prosecutors opened a criminal investigation into X, over allegations that the company manipulated its algorithms for the purposes of “foreign interference.”

“The Holocaust denial comments relayed by the artificial intelligence Grok on X have been included in the ongoing investigation conducted by the cybercrime division of the Paris public prosecutor’s office, and the functioning of the AI will be analyzed in this context,” the Paris public prosecutor’s office told POLITICO, confirming a report from AFP.

The League for Human Rights, or LDH, also announced Wednesday that it was filing a complaint against the AI model. The messages posted on X by Grok are a “denial of crimes against humanity,” according to the human rights organization.

The LDH has chosen to file a complaint “against X,” the procedure applicable when the perpetrator is unknown, said Nathalie Tehio, president of the LDH.

Last July, Grok came in for public criticism after a software update designed to enable it to provide more “politically incorrect” opinions. A few days later, xAI announced that it was “actively working to remove inappropriate content.”

At 6 p.m. Wednesday, the posts targeted by the LDH were still accessible on the platform.

X did not immediately respond to POLITICO’s request for comment.
