Grok, the chatbot created by Elon Musk’s xAI, began responding with violent posts this week after the company tweaked its system to allow it to offer users more “politically incorrect” answers.

Elon Musk on Thursday unveiled Grok 4, the latest AI model from xAI, his multibillion-dollar initiative to rival OpenAI and Google.

Since Musk bought what was then known as Twitter in 2022, he has cut back on moderation. Extremist content has increased, causing advertisers to pull away from the platform.
