Tstars-Tryon 1.0：面向多样化时尚单品的鲁棒且逼真的虚拟试穿系统

摘要

近期图像生成与编辑技术的突破为虚拟试穿开辟了新机遇，但现有方法仍难以满足复杂的现实需求。我们推出Tstars-Tryon 1.0——一个具备鲁棒性、真实感、多功能性及高商用效能的虚拟试穿系统。首先，该系统在极端姿态、强烈光照变化、运动模糊等复杂场景下仍保持高成功率；其次，生成结果具有照片级真实感，能精细保留服装纹理、材质属性与结构特征，并显著规避常见AI生成伪影；第三，除服装试穿外，模型支持8大时尚品类、最多6张参考图的灵活多图组合，并实现人物身份与背景的协同控制；第四，通过深度推理优化突破商用延迟瓶颈，实现近乎实时的生成体验。这些能力得益于端到端模型架构、可扩展数据引擎、鲁棒基础设施与多阶段训练范式的系统化整合。大规模评估及产品部署表明，Tstars-Tryon 1.0在整体性能上处于领先地位。为促进后续研究，我们同步发布了完整评估基准。该模型已在淘宝APP实现工业级部署，为数百万用户处理上千万次请求。

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.
