The author connected Jev to the raw controls of a driving simulator and shows it driving in real time, emphasizing real-time response rather than frame-by-frame video generation.
JEV CAN DRIVE! 🤯 I hooked up Jev to the raw controls of a driving simulator, this video shows him driving in realtime. Realtime is the kicker here. Asking a model what to do every 50ms then rendering that into a "realtime" video is one thing, but in this simulation I wanted to
A developer used TypeSafe Jev to make a Rubik's Cube solve itself with a beginner method in 94 moves, like a person rather than the 22-move optimal solution; Jev is not an LLM and answers one question with a probability in ~250ms.
A developer experiments with GPT for reasoning and JEV for decision-making to control a LeRobot arm, with updates promised soon.
The author tested Jev as a real-time robotics policy in MuJoCo; after initial struggles, each update was split into two calls—decide what to do next, then how to move the arm and gripper. Jev does not accept images and receives simplified geometry and contacts as text.
