Jev Drives a Simulator in Real Time
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.
The author shares a 4B Jev-style judge trained with public data and their own recipe, beating multimodal Jev-style models up to 27B on RoboPulse, RoboRewardBench, and real-robot rollouts, while noting specialist reward models still win at home.
3/6 How far can public data + our recipe take a 4B Jev-style judge? It beats every multimodal Jev-style model we tested, up to 27B, on RoboPulse, RoboRewardBench and real-robot rollouts. Specialist reward models still win at home: Robo-Dopamine on progress, RoboReward on
