RecoGEM serves generative recommendation by coordinating candidate transitions, state, and live updates in a recommendation-aware runtime, while a specialized engine executes step-specific decoding profiles for beam search over semantic identifier sequences. For OneModel at batch size 32, it reports 1,053 QPS and 30.8 ms P99 versus GeneralGen’s 366 QPS and 89.0 ms; this measures serving performance, not recommendation quality.
