Browser Use's open-source Jev agent searches Google Flights in 7 seconds for $0.0039

Browser Use open-sourced jev-ultrafast, a browser agent built with TypeSafe's Jev (8.6k GitHub stars). It searched Zurich→London flights on Google Flights in 7.1 seconds at a cost of $0.0039, with the demo shown at normal 1x speed.
- Each observation produces a fresh element table exposing only supported operations (CLICK, TYPETEXT, SELECT, SCROLL, WAIT, DONE, BLOCKED) and valid targets — a dynamic, indexed action space
- Jev picks the operation and element; text generation happens only for TYPETEXT, and small models handle input fields, cutting token usage and decision space per step
- The team also opened a waitlist for Browser Use Cloud
Browser agents' speed and cost are entering genuinely usable territory.
