Tstars-Tryon 1.0：實現多元時尚單品的強健逼真虛擬試穿

摘要

近期圖像生成與編輯技術的突破為虛擬試穿開闢了新可能，但現有方法仍難以滿足複雜的實際應用需求。我們推出商用級虛擬試穿系統Tstars-Tryon 1.0，該系統具備強韌性、真實性、多功能性與高效能四大特點。首先，系統在極端姿勢、劇烈光照變化、動態模糊等複雜真實場景下仍保持高成功率；其次，生成結果具有照片級真實感，能精細還原服裝紋理、材質屬性與結構特徵，同時有效規避常見的AI生成瑕疵；第三，除常規服飾試穿外，模型支援8大時尚品類的靈活多圖組合（最多6張參考圖），並可協調控制人物身份與背景元素；第四，針對商業部署的延遲瓶頸，系統進行深度推理優化，實現近乎即時的生成速度以保障用戶體驗。這些能力得益於端到端模型架構、可擴展數據引擎、穩健基礎設施與多階段訓練範式的系統化設計。大量評估與大規模產品部署表明，Tstars-Tryon 1.0在整體性能上處於領先地位。為推動後續研究，我們同步發布了綜合評估基準。該模型已在淘寶App實現工業化部署，日均服務數百萬用戶，處理千萬級請求。

Recent advances in image generation and editing have opened new opportunities for virtual try-on. However, existing methods still struggle to meet complex real-world demands. We present Tstars-Tryon 1.0, a commercial-scale virtual try-on system that is robust, realistic, versatile, and highly efficient. First, our system maintains a high success rate across challenging cases like extreme poses, severe illumination variations, motion blur, and other in-the-wild conditions. Second, it delivers highly photorealistic results with fine-grained details, faithfully preserving garment texture, material properties, and structural characteristics, while largely avoiding common AI-generated artifacts. Third, beyond apparel try-on, our model supports flexible multi-image composition (up to 6 reference images) across 8 fashion categories, with coordinated control over person identity and background. Fourth, to overcome the latency bottlenecks of commercial deployment, our system is heavily optimized for inference speed, delivering near real-time generation for a seamless user experience. These capabilities are enabled by an integrated system design spanning end-to-end model architecture, a scalable data engine, robust infrastructure, and a multi-stage training paradigm. Extensive evaluation and large-scale product deployment demonstrate that Tstars-Tryon1.0 achieves leading overall performance. To support future research, we also release a comprehensive benchmark. The model has been deployed at an industrial scale on the Taobao App, serving millions of users with tens of millions of requests.
