Mingyu Liu explains that open models are crucial for physical AI due to the varied sensor setups and unique requirements of different robots and devices. Open models allow for customization and fine-tuning, enabling better adaptation to specific hardware and use cases, which is difficult with one-size-fits-all API solutions.
“So I think, for example, one thing, a physical AI model, one popular physical AI model is a policy model.”
“So every robot has a different kind of sensor setup. Right? Robots have two eyes. Some robots have cameras mounted on the gripper. And self-driving car, some car has 11 cameras. Some have seven. You know, some have a LiDAR sensor. So every physical device, every robot see the world differently, right?”
“So I think open model gives you the innovation power. So you can customize open model to better talent for your Fitch Guide use case. This is important, right?”
