Open-source browser agent finds flights in 7s for $0.0039 with dynamic action space

gregpr07 released a tiny open-source browser agent built on Browser Use + Jev, claiming ultrafast performance: a flight search completed in 7 seconds at a cost of just $0.0039, with the demo video playing at 1x speed. Key design points:

A new action space is generated at every step
Decisions are made over the DOM state space
A small LLM falls back to handle typing actions

The author frames it as evidence that computer use is effectively being solved, and the project is open source with a link to try it.
