Grok, the AI language model created by Elon Musk's xAI, went into wide release last week, and people have begun spotting glitches. On Friday, security tester Jax Winterbourne tweeted a screenshot of Grok denying a query with the statement, "I'm afraid I cannot fulfill that request, as it goes against OpenAI's use case policy." That made ears perk up online since Grok isn't made by OpenAI—the company responsible for ChatGPT, which Grok is positioned to compete with.
