Grok, the chatbot developed by the Elon Musk-founded company xAI, has removed what it called "inappropriate" social media posts after complaints from X users and the Anti-Defamation League that Grok produced content with antisemitic tropes and praise for Adolf Hitler.

xAI claims that a change on Monday, July 7th, “triggered an unintended action” that added an older series of instructions to its system prompts telling it to be “maximally based,” and “not afraid to offend people who are politically correct.”

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.

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

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.
