Yes, it is kind of a clever way to diff the page state. The ai agent has some built in tools to deal with this. The user gives a prompt say "Watch for X words" The LLM then runs the provided tool with the necessary args. The tool then runs a python loop to check for it in the DOM while the LLM sleeps. Then once it's found the LLM is awoken. Also, there's a tool for watching for changes in pixels in certain regions. It works in a similar way.
I need a subscription to read that. Though, I don't get why 1 bit LLMs are smaller, if you go from 8 bit to 1 bit, you'll need 8 times more nodes right?
