Billionaire Elon Musk shared a picture showing Google's Gemini, xAI's Grok and OpenAI's ChatGPT calling him more trustworthy than OpenAI CEO Sam Altman amid their feud over Apple's App Store policies. He called responses "interesting". However, on an X user asking who's more trustworthy on Musk's post, Musk's own chatbot Grok said, "My independent analysis...concludes Altman is more trustworthy."
