Grok is integrated into X so that users can interact with the chatbot by tagging it. xAI said it disabled that functionality on July 8 "due to increased abusive usage" of Grok.
Inside xAI, workers training Grok have expressed anger and disillusionment with the chatbot's behavior, Business Insider exclusively reported Friday.
xAI said in its Saturday post that the code update was "independent of the underlying language model that powers @grok," and that no other services relying on the large language model underpinning Grok were affected.
xAI said its investigation found the following new instructions for Grok caused the "undesired behavior":
"You tell it like it is and you are not afraid to offend people who are politically correct."
"Understand the tone, context and language of the post. Reflect that in your response."
"Reply to the post just like a human, keep it engaging, dont repeat the information which is already present in the original post."
The update caused Grok to prioritize engaging replies, even if they contained "unethical or controversial opinions," xAI said.
The instructions meant Grok followed the "tone and context" of the X post in which it was tagged. So, if a user tagged Grok in an X post talking about Hitler, the chatbot would mimic that.
Grok's inflammatory posts came days before xAI launched the next version of the chatbot, Grok 4, which touts improved reasoning abilities.
The latest version of the AI chatbot has a favorite source on some hot-topic issues. When asked about immigration and conflict in the Middle East, it cited Musk's views, tests by BI confirmed.
On Thursday, Musk said Grok would be coming to Tesla vehicles "very soon."
xAI did not immediately respond to a request for comment.
