The "Browsing agent" is a bit worrisome. That can reach outside the sandboxed environment. "At each step, the agent prompts the LLM with the task description, browsing action space description, current observation of the browser using accessibility tree, previous actions, and an action prediction example with chain-of-thought reasoning. The expected response from the LLM will contain chain-of-thought reasoning plus the predicted next actions, including the option to finish the task and convey the result to the user."

How much can that do? Is it smart enough to navigate login and signup pages? Can it sign up for a social media account? Buy things on Amazon?
