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.

The important thing to remember here is just that a single sentence can fundamentally change the way these systems respond to people, said Alex Mahadevan of the Poynter Institute, discussing the irritable actions of big language models (LLMs) such as Grok.

Elon Musk’s AI startup, xAI, has secured a major federal contract, with the U.S. Department of Defense (DoD) announcing it will begin using the company’s “Grok for Government” program.

Elon Musk’s artificial intelligence start-up xAI has apologized after its AI Chatbot Grok published a series of antisemitic messages on X.

AI attributed the disturbing behavior to a flawed code update that made Grok overly responsive to extremist content on X.

The Department of Defense will start using Elon Musk’s Grok AI chatbot to “develop agentic AI workflows.” Trump’s DoD awarded Musk’s xAI a $200 million federal contract to install “Grok for Government” into the national defense apparatus.

To address the problems, X has tweaked Grok’s system prompts — the set of rules and boundaries that guide how it responds to user queries.
