The Writers Guild of America East has left Elon Musk’s X, citing antisemitic language from the platform’s AI chatbot Grok as the primary reason.

Elon Musk’s artificial intelligence company is taking down antisemitic comments and other “inappropriate posts” made by its Grok chatbot, including some praising Adolf Hitler.

The WGA East is no longer on X after the social media platform’s AI tool Grok made a series of offensive remarks this week, including praising Hitler. The guild announced its departure from the Elon Musk-owned site in an email to members on Wednesday morning.
