Airbnb added Push Mode and near-real-time model transformation to its open-source feature platform Chronon, cutting sequence-recommendation embedding lag from nearly two days to 10-30 seconds. The change lifted offline NDCG by 1.67% and increased non-cancelled bookings by about 0.33% in online A/B tests, with the capabilities contributed back to the public Chronon repository.
