The trick: Self-Marked
A robot that scores 87% at a site it has never seen.
On the scorecard the robot's maker wrote.
Dyna Robotics says Dyna-2, trained on a million hours of human video, walks into a brand-new customer site and passes 87% of its quality bar with no site-specific retraining, up from 46% for the previous model.
Before you read on. Your call?
TRUE, BUT
87% on their own eval
the numbers come straight from Dyna's own page, self-evaluated, with no independent replication. 'Quality' is not a public benchmark, it is 'the quality, throughput and reliability the customer site requires', a bar Dyna defines. The eval spans about 14 tasks on three robots from one lab.
The twist
the 'no retraining' headline has an asterisk in Dyna's own materials. Adapting to a new robot platform still takes 'a few hours of local fine-tuning'. Zero-shot holds for the one deployment they describe, and quietly does not for the general case they imply.
