Hugging Face's $399 bipedal robot runs a reinforcement-learning locomotion policy trained in simulation — the same fundamental approach used in six-figure research humanoids. Jet West digs into what the 'cute toy' framing obscures: the engineering, the limits of the word 'open,' and the timing of a reported $13 billion Nvidia acquisition.
