The Browser Arena
Compare per-action speed inside a running session: navigate, wait, screenshot, read, click, back. Actions per second, tail latency, drift, and cost per 1,000 actions.
Once a session is up, how fast does each agent step complete? Every session runs a fixed loop of ten actions on Wikipedia at a 1920x1080 viewport, each action timed on its own. A session only counts as a success when every action succeeded. Methodology.
