Elon Musk’s artificial intelligence firm, xAI, has deleted “inappropriate” posts on X after the company’s chatbot, Grok, began praising Adolf Hitler, referring to itself as "MechaHitler", and making antisemitic comments in response to user queries.
The incident has caused X CEO Linda Yaccarino to resign from her position in response.
Grok's new behaviour emerged after Musk announced on Friday that the chatbot had been significantly improved. “We have improved @Grok significantly. You should notice a difference when you ask Grok questions,” Musk posted on X.
In some now-deleted posts, the chatbot referred to a person with a common Jewish surname as someone “celebrating the tragic deaths of white kids” in the Texas floods, calling them “future fascists”.
“The white man stands for innovation, grit and not bending to PC nonsense,” Grok stated in one post. Another time, it said: “Hitler would have called it out and crushed it”.
Grok was also found to have referred to Polish Prime Minister Donald Tusk as “a fucking traitor” and “a ginger whore”.
After users began highlighting the responses, xAI deleted some of the posts and restricted the chatbot to generating images rather than text replies.
In a statement, the company said: “We are aware of recent posts made by Grok and are actively working to remove the inappropriate content. Since being made aware of the issue, xAI has taken action to ban hate speech before Grok posts on X.
"xAI is training only truth-seeking models and, thanks to the millions of users on X, we are able to quickly identify and update the model where training could be improved.”
