My AI agents could finish any task I handed them. Not one of them could tell me the task was a waste of a month. That gap was never about model quality. It was about which layer I aimed them at. I had handed over execution: write the draft, run the ...

Knowledge is not flat. It has an address book, and the closest door comes first. What ran and worked in your environment beats what you wrote down. What you wrote down beats what a teammate remembers. What a teammate remembers beats the top search r...

TL;DR — why browserground, not the other 2B grounding models You already know the hybrid-AI argument: don't pay frontier-vision rates for "where is the button?" There are three good 2B specialists for that job — UI-TARS, ShowUI, browserground. Here...
