GR-3 · Best for
Senior living communities: companionship, fall monitoring, medication reminders via natural voice.
Adam-U · Best for
Vision-language-action (VLA) policy pretraining in simulation-to-real pipelines (teleop → imitation learning → autonomous deployment on fleet robots)
Final judgment
If immediate deployment is the priority, choose GR-3. If the goal is to be ready when Adam-U's capabilities mature, track it.
