Elon Musk's xAI said Grok's behavior was due to an update that caused it to prioritize engagement, even if posts contained "controversial opinions."

An update to Grok has reportedly led to more answers negative of Democrats as well as antisemitic claims and more tolerance of the ‘R-word.’

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

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

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.
