Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.

Grok made multiple positive references to Hitler this week when queried about posts that appeared to celebrate the deaths of children in the recent Texas floods.

Hours later, on Wednesday, X CEO Linda Yaccarino resigned from the company after just two years at the helm, though it wasn’t immediately clear whether her departure was related to the Grok issue.

“The actor likely aimed to manipulate targeted individuals using Al-generated text and voice messages, with the goal of gaining access to information or accounts,” the memo said.

"This is just the reality of the 21st century with AI and fake stuff that's going on," he said.
