fastbrowse lists everything on a page that can be clicked or filled in, and Jev picks one. Because it chooses from a list rather than inventing, it cannot click something that is not there. A separate language model plans and reads, and plain code handles checks, safety and passwords.
Every claim in its answer quotes the page word for word. In the authors' own test of 14 tasks, including sign-ins, a checkout and a Google Flights search, it passed 41 of 42 runs at well under a cent per task.
Highly experimental and not yet recommended for production. Written in Python.
