Elon Musk appeared to give a mocking response to his artificial intelligence chatbot’s Hitler-praising comments on X. On Tuesday, the chatbot called Grok—created by Musk’s company xAI—started giving unhinged responses to users on the billionaire’s social media platform.

Grok, the chatbot developed by the Elon Musk-founded company xAI, has removed what it called "inappropriate" social media posts after complaints from X users and the Anti-Defamation League that Grok produced content with antisemitic tropes and praise for Adolf Hitler.

AI says it is actively working to remove 'inappropriate' posts. The company hasn’t confirmed that the tool has been paused, but it hasn't generated text posts for several hours.
