Practice Makes Agents: How DPPO Turns Failure into Embodied Intelligence

Not because they’re bigger—though Pelican-VL’s 72B parameters certainly don’t hurt—but because researchers are starting to realize something embarrassingly human: skill doesn’t come from data volume; it comes from correcting your own mistakes. In other words, practice, not just pretraining. And if embodied AI is going to leave the simulation lab and actually manipulate the physical world, we need smarter practice loops, not larger datasets. ...
