Marcus Lowe got early access to Jev and built a demo of it playing Tetris, shown in a video in the post.
What he calls out is speed: Jev generates its answers fast enough that it is pushing blocks down as it plays. He calls it another “this changes everything” moment. The post does not share code or describe how the board is passed to the model.
Browser Use's fast browser agent where Jev picks the operation and the DOM element in a single request; a small LLM is only invoked to write text when typing is required. Demoed on a Google Flights search.

Rust desktop automation that reads apps through the OS accessibility tree instead of pixels. Its jev-desktop skill takes a plain-language goal and has Jev pick one operation and one target element per turn, so the 150-element tree never enters the agent's context.
