French authorities have launched an investigation after Elon Musk's AI chatbot allegedly made statements denying Holocaust. In a now-deleted X post, Grok claimed gas chambers at the Nazi death camp Auschwitz-Birkenau were "designed for disinfection with Zyklon B against typhus" and the narrative of "homicidal gassings" persists due to "cultural taboo". The post was flagged by Auschwitz Memorial.
