Jev holds high NDCG@10 across three Amazon domains while its latency grows far more gradually than pointwise Qwen
On Movies and TV, Video Games, and Books from Amazon Reviews 2023, the study builds controlled hard candidate sets from SASRec's highly ranked negatives (candidate sizes 10 to 100) and compares Jev, a decision-oriented "System One Model" from TypeSafe AI, against SASRec, DCNv2, and pointwise and listwise Qwen2.5 7B Instruct rerankers, finding that Jev maintains strong recommendation effectiveness (NDCG@10, Hit Rate@10, MRR) while its observed serving latency grows substantially more gradually than pointwise Qwen, though it remains far above recommendation-specific models.
