Robotics Is Where Jev Belongs: The Decision Layer Between Motion and Planning
Robot control is stacked in layers. Servos run near 1000 Hz, VLA models at 5–50 Hz, task planning below 1 Hz. In between sits a layer that only has to pick the next action, and today we fill it with branching logic or a large language model that is too slow. Jev, a model that writes nothing, is a part built for exactly that slot. Here is what Jev is, how to wire it into a robot, and where safety has to stay separate.
