BUYING THE HYPE
▸ HYPE VS REALITY
Jev Ultrafast is marketed as the fastest and cheapest web agent with a dynamic, indexed action space, capable of completing tasks like Zürich to London on Google Flights in 7.1 seconds.
While demonstrated as a cool implementation, users report that the project is broken, fails to run on the actual run demo button, and contains concerning telemetry features that can leak credentials to PostHog.
Although the browser agent shows impressive speed in demonstrations, multiple users report functionality issues and execution errors.
This verdict would change if new, credible evidence emerged contradicting the claim "Completes tasks like Zürich to London on Google Flights in 7.1 seconds" — for example, an independent test or investigation finding the opposite of what's currently confirmed.
