Browser agents are often slow because every click requires a full model call to decide what to do next. jev-ultrafast is a browser agent that shortens that loop: it gives the model a numbered table of the page's elements and a small fixed set of operations, and it asks for the operation and the target in a single request.
Each page observation produces a new element table. The available operations are click, type text, select, scroll up, scroll down, wait, done and blocked. A small separate language model writes text only when the operation is typing. The README states that no site-specific scripts or prepared field values are used in the policy.
The README reports a Zurich to London search on Google Flights completing in 7.1 seconds from one natural-language goal. That figure comes from the project itself and was not independently checked.
Running the demo needs an API key for TypeSafe's Jev service and a key for the text model, plus Chrome connected through the project's browser harness. The README also advertises a waitlist for a hosted cloud version, so part of the design depends on a commercial service.
jev-ultrafast is placed in Assess at the center position. The repository is MIT licensed and had about 10,500 stars and 64 open issues when checked, but it was created on 2026-09-16, the headline speed is unverified, and it depends on an external hosted model service. There is no first-person use.
