OneTrans-GSR: A Generative Slate Ranking Paradigm Unifying Reranking and Mix-Ranking with One Autoregressive Transformer

OneTrans-GSR is a decoder-only policy that extends ByteDance's deployed OneTrans backbone to generate full exposure slates end-to-end, replacing hand-crafted rules in reranking and mix-ranking. A reward model scores complete slates and guides reinforcement learning toward slate-level and long-term objectives. In online A/B tests it improved GMV per user by 2.63%, advertiser value by 2.06% and repurchase rate by 2.03%, while cutting end-to-end latency across both stages by 13%.
