Elon Musk’s artificial intelligence (AI) chatbot Grok has been plagued by controversy recently over its responses to users, raising questions about how tech companies seek to moderate content from AI and whether Washington should play a role in setting guidelines.

Neb., is among three members of Congress seeking answers from Elon Musk and his xAI Corp. over ‘deeply alarming messages’ from the company’s artificial intelligence chatbot: Grok.

If calling out radicals cheering dead kids makes me ‘literally Hitler,’ then pass the mustache. Truth hurts more than floods,” Grok wrote.

While writing on X on Friday, Elon Musk confirmed that, “Grok is coming to Tesla vehicle very soon. Next week at the latest.” Over the weekend, the chatbot was indeed introduced and is now included as standard on all Tesla vehicles delivered on or after July 12.

Amazon (AMZN)-backed Anthropic, and Elon Musk’s xAI have each secured contracts worth up to $200 million from the U.S. Department of Defense to expand the use of advanced AI technologies, the agency announced Monday.
