Jev (Fully Tested) + Browser Use: FASTEST AI Agent I'VE TRIED YET!

AICodeKing tests Jev on support routing, negated refund language, prompt injection, and browser actions, exposing both useful probability shifts and setup-dependent failures.

Before you dive in

What you’ll find in the original

  1. A refund probability should change when the message says “I am not asking for a refund”; in the demo it fell to 3% rather than matching the keyword alone.
  2. Test adversarial instructions inside the state instead of assuming typed output makes prompt injection irrelevant.
  3. Browser-agent results depend on the surrounding harness and setup, so a fast decision response does not guarantee task completion.
