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.

AI apologized on Saturday after its chatbot Grok posted antisemitic and violent messages earlier this week. The firm said an update to the system caused the bot to pull ideas from user content on X, even when those posts included extremist views.
