The Download: OpenAI's agent, and what to expect from robotics

What's new: After weeks of buzz, OpenAI has released Operator, its first AI agent. Operator is a web app that can carry out simple online tasks in a browser, such as booking concert tickets or filling an online grocery order. The app is powered by a new model called Computer-Using Agent--CUA for short--built on top of OpenAI's multimodal large language model GPT-4o. Why it matters: OpenAI claims that Operator outperforms similar rival tools, including Anthropic's Computer Use and Google DeepMind's Mariner. The fact that three of the world's top AI firms have converged on the same vision of what agent-based models could be makes one thing clear.
