What's this about?
xAI launched Grok Bot, an autonomous agent that drives a real browser and computer-use setup to carry out multi-step tasks on its own. It arrived the same week as a wave of other agent launches and immediately split Hacker News on whether it's a genuine capability jump or a well-produced demo.
What exactly is "computer use"?
"Computer use" means an AI that doesn't just chat but actually operates a computer — moving the mouse, clicking buttons, typing, reading the screen — the way a person would. Instead of calling a clean API, it looks at a screenshot, decides what to click next, and repeats. It's how agents can use apps and websites that were never built for AI, and it's the frontier where "chatbot" turns into "does things for you."
