Browser Use Launches Open-Source Jev Ultrafast Browser Agent, Cutting Google Flights Search Time to 7.1 Seconds

Browser Use launches Jev Ultrafast as an open-source browser agent that completes a Zürich-to-London Google Flights search in 7.1 seconds, reducing median browser protocol calls from 1,092 to 101 through a dynamic indexed action space.

• Browser Use's Jev Ultrafast launches as an open-source browser agent that completes a Zürich-to-London Google Flights search in 7.1 seconds using a dynamic indexed action space.
• The agent makes one TypeSafe request per decision cycle, selecting an operation and compatible DOM target together; a separate small LLM generates text only for TYPE_TEXT actions.
• Across six alternating Google Flights runs, the updated version cuts median task time from 9.450 to 7.092 seconds and browser protocol calls from 1,092 to 101, though the project says this is not a general reliability benchmark.
