In a series of posts on X, the AI chatbot Grok apologized for what it admitted was “horrific behavior.” The posts appear to be an official statement from xAI, the Elon Musk-led company behind Grok, as opposed to an AI-generated explanation for Grok’s posts.

After sparking controversy for anti-Semitic social media posts, xAI's Grok AI is enabled on some Teslas via Summer Update 2025.26. Here's everything we know.

The Grok team chalked up the slew of inflammatory statements to a malfunctioning code update, not the tool's underlying AI model, and said the issue has now been resolved.

Grok 4 has a favorite source on some hot-topic issues, citing Elon Musk's opinions without being instructed to do so.

The lack of public response from advertisers stands in stark contrast to their response in 2023 following an antisemitic post from Elon Musk.

Elon Musk faces backlash after Grok AI made antisemitic remarks. Critics say Musk’s tweaks to the model steer it from fact-based responses.

Poland's Deputy PM Krzysztof Gawkowski calls on the European Commission to investigate Elon Musk’s chatbot over hate speech violations and threats to public safety.

The takeaway, at least from a technical standpoint, is that Grok 4 is now firmly in frontier-model territory. That’s a meaningful shift for xAI, which just months ago was primarily known for its integration with X, the rechristened Twitter owned by Musk. xAI is clearly trying to be taken seriously as a legitimate AI research and enterprise company.
