Page loops where Jev picks an action and a browser runtime performs it. 5 stories.
Lightpanda's hostel script counts browser memory, and the Jev clock stays in the post
Lightpanda posted that 129 of its browser agents fit on one laptop against 12 Chrome agents, with 11 times less memory on a booking site, and that a hostel task took 6.7 seconds with Jev against 14.1 seconds with gemini-3.8-flash. The linked script measures resident memory and does not call a model. Its notes for the default San Francisco hostel page are 161 MB against Chrome at 1,654 MB.
One screenshot decision was $0.0002 on Jev and $0.032 on Opus 5
awlevin's macOS loop reads the screen with OCR and asks Jev which action comes next. On one shared screenshot the README prints $0.0002 and 0.13 to 0.38 seconds for Jev, against $0.032 and 5.2 seconds for Claude Opus 5 on the bare image. The same page says Opus read the dates off the pixels, and this loop annotates dates in code before the classifier runs.
dejevu books the same Flights search faster than the published Jev demo, on another machine
Idov Mamane posted dejevu, an MIT browser loop that sends one JSON action to an ordinary chat model. On the README's table, llama-3.3-70b on Groq finishes the Flights check in 5.63 seconds against jev-ultrafast's published 7.09 seconds. The Jev column was not rerun here. That Groq route costs more per run.
Browser Use wires Jev into the click loop: 7 seconds, $0.0039
Gregor Zunic showed a 1x-speed Google Flights run where Jev picks the action and DOM target each step, and a small LLM types only when it has to. On September 30, 2026 a desk loop on three routes never left the Google Flights start page, so date, price, and flight number were not confirmed there.
Stagehand, Chrome, and a11y trees: computer use as a Jev question
Kyle Jeong of Browserbase and other builders structured computer-use around structured observation, typed queries, and automated execution, reporting sub-cent task costs. On September 30, 2026 the same task reached the Jevons paradox article on Wikipedia and stopped short on DuckDuckGo and Britannica.
