Dyna-2: General Purpose Physical Agents with Hour-Long Autonomy — Jason Ma, Dyna Robotics
Hour-long autonomy on physical robots is a meaningful threshold. World Action Models—learned predictive models of environment dynamics—are a real technical challenge that affects whether agents can plan and act reliably over extended horizons. If Dyna's approach is working, this signals progress on a bottleneck that matters for real deployment. Read the episode to understand their model architecture.
