Xingyuan Intelligent launched Chorus, a cross-ontology data engine for robots
pretraining that converts human-operation video from devices such as smart
glasses and wrist cameras into robot-usable training data. Internal tests show
an effective conversion rate of about 85%. With 16 ontology adapters and 3x
instruction augmentation, Chorus delivers roughly 40x expansion of effective
training data and cuts equivalent unit training cost to about 5 yuan/hour.
