Meet Grok, the first technology out of Elon Musk’s new AI company, xAI. Grok, the company said, is modeled on “The Hitchhiker’s Guide to the Galaxy.” It is supposed to have “a bit of wit,” “a rebellious streak,” and it should answer the “spicy questions” that other AI might dodge, according to a Saturday statement from xAI. The prototype is in its first two months of training and is only available to a select group of users before a wider release. Musk is positioning xAI to compete with OpenAI, Inflection, Anthropic and others.
