Elon Musk’s artificial intelligence startup xAI is rolling out Grok 4 just months after releasing its previous iteration, underscoring the frenetic pace of AI development.

The AI chatbot Grok created by Elon Musk’s company xAI is once again spewing antisemitic hate speech — this time after Musk’s team claimed to have “improved” it.

Social media posts on the X account of the Grok chatbot developed by Elon Musk’s company xAI were removed on Tuesday after complaints from X users and the Anti-Defamation League that Grok produced content with antisemitic tropes and praise for Adolf Hitler.
