AI explained why Grok 4 seemed to search for Elon Musk's opinions when asked about some hot-button topics.

Elon Musk's xAI startup is swimming in controversy after launching Grok 4, the latest version of its snarky AI chatbot. Last week, the company boasted that Grok 4 achieved higher scores than quite a few other large language models (LLMs) on various industry benchmarks.

The Department of Defense has announced contracts with four leading artificial intelligence companies, including Elon Musk's xAI, a week after its Grok chatbot allegedly disseminated racist rhetoric online.

WASHINGTON - Elon Musk's AI company, xAI, has secured a $200 million contract from the US Department of Defense, despite recent backlash over its chatbot Grok. The deal aims to boost artificial intelligence capabilities across military operations.

Elon Musk’s company xAI apologized after Grok posted hate speech and extremist content, blaming a code update and pledging new safeguards to prevent future incidents.

People who pay for access to SuperGrok can now try the AI chatbot’s new “Companions” avatars, xAI owner Elon Musk announced Monday morning. The companions available currently include Ani, an anime avatar, and Rudy, a cartoony red panda.

The Department of Defense under Secretary Pete Hegseth has been fixated on buzzwords like “warfighting” and “warfighters,” and adopting new AI tools is part of that mission, according to leaders at the agency. And Monday’s press release was filled to the brim with similarly grandiose language.

Elon Musk ruled out a merger between Tesla and xAI but said he plans to hold a shareholder vote on investment in the artificial intelligence startup by the automaker, in the latest step to deepen integration across his business empire.
