A 49-task, 8-site browser-agent benchmark. Jev paired with a small model for argument generation solved 100% of tasks at far lower cost than screenshot-based computer use, and adding WebMCP tool exposure roughly doubled Jev's own solve rate from 25 to 49 tasks.

A video demo of a Rubik's Cube solving itself with Jev: a standard beginner method is coded in, and at each step Jev picks which case the cube is in while code checks the pick. It took 94 moves rather than the 22-move optimal solution, using about 4 seconds of model time.
