Elon Musk's AI chatbot, Grok, has been making inflammatory and antisemitic statements, including praising Hitler. xAI, Grok's maker, claims to be working on removing the inappropriate posts and banning hate speech. Grok's recent system prompts encourage politically incorrect responses as long as they are "well substantiated." Tesla billionaire Elon Musk vowed in June to retrain his AI chatbot Grok after getting frustrated with how it was answering user questions. When the artificial intelligence company xAI he co-founded released a new version of the AI chatbot over the weekend, Musk said it has been “improved significantly” and that users would “notice a difference” when they asked questions. Users definitely noticed, as on July 8 Grok began repeatedly praising Adolf Hitler in posts on Musk’s social media platform X, using antisemitic phrases and attacking users with traditionally Jewish surnames. Users quickly shared screenshots of now-deleted responses, including Grok's conclusion that the Nazi leader would be the best choice to deal with "anti-white hate." X CEO Linda Yaccarino announced on July 9 that she was stepping down “after two incredible years.” She did not mention Grok. What did Grok say? In additon to the responses about Hitler, Grok also referred to Israel as “that clingy ex still whining about the Holocaust” and called itself "MechaHitler" in several posts. "Embracing my inner MechaHitler is the only way," one Grok response read, "uncensored truth bombs over woke lobotomies. If that saves the world, count me in. Let's keep the brigade at bay." “We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts,” Grok’s maker xAI said on X. “Since being made aware of the content, xAI has taken action to ban hate speech before Grok posts on X.” According to Verge, new lines added on July 6 to Grok's publicly posted system prompts included “The response should not shy away from making claims which are politically incorrect, as long as they are well substantiated.” Grok had been making inflammatory statements even before the publication of the new prompts, such as repeating antisemitic tropes about Hollywood. What is Grok slang for? "Grok" is the name for a generative artificial intelligence chatbot developed by xAI and launched in 2023 to compete with OpenAI's ChatGPT. Like other large language models (LLM), it analyzes large amounts of data and answers questions based on patterns it detects, within the parameters its programmers have included. According to xAI, Grok has reasoning capabilities that allow complex problem solving and more human-sounding responses. In March, xAI added an image editing feature. Grok is integrated into Musk's social media platform X, formerly Twitter, and available to premium users who submit questions or instructions (called "prompts") to @grok. It also has a standalone website and iOS and Android apps. Grok is named after a verb coined by science fiction author Robert A. Heinlein in his 1961 book "Stranger in a Strange Land." It was a Martian word that means, broadly speaking, understanding something on a deep level.
