团队介绍：国际电商是以TikTok为载体的电商业务（也称为TikTok Shop），致力于成为用户发现并获取优价好物的首选平台，在直播电商、视频内容电商、货架电商等多场景下，国际电商希望能为用户提供更个性化、更主动、更高效的消费体验，为商家提供稳定可靠的平台服务，致力于新奇好物畅销全球，美好生活触手可得的使命。 Data-电商团队是国际电商的核心算法技术力量，专注于电商领域的算法创新，帮助用户高效发现感兴趣的商品，保障用户的购物安全，提升交易各环节的智能化水平。在这里，你将与一流的产品和技术团队合作、钻研，一起应对技术和业务上的挑战，推动技术在电商场景的深度落地。
课题介绍： 国际电商生态中沉淀了用户行为、商品图文、多媒体内容、商品销量与物流时序等海量异构数据，但传统模型在长周期预测、跨模态理解及复杂决策推理上仍存在明显瓶颈。 本课题拟以大模型为基础，联合构建面向国际电商场景的基础大模型，将用户、商品、内容、物流与库存等关键信息统一建模，并在其之上设计可插拔的Agent框架，系统整合任务规划、工具调用、多轮交互与环境感知等能力，从而在需求预测、流量分发与个性化推荐等链路中实现端到端的智能决策。
课题挑战： 1、异构融合与对齐：统一建模用户行为序列、商品销量时序信号与多模态商品内容，完成高维时序与图文表征的深度语义对齐； 2、推荐大模型与世界模型协同：把推荐问题定义还原为用户推荐列表的生成问题，基于大模型的技术完成端到端推荐建模； 3、推荐物品的Tokenizor：如何把亿级别的物品进行多模态和特征语义编码，支撑后续训练和生成任务，处理几十TB级别的用户行为Tokens的预训练，通过模型结构和训练方式拉高Scaling Law曲线，把各类推荐任务重构为后训练任务，以RLVR的思路进行推荐任务建模，最大化GMV和体验价值，训练推理优化，基于SGLang 等大模型推理套件定制构建高性能的推荐服务； 4、电商多模态大模型：构建面向电商领域的多语言多模态大模型，在核心电商场景达到SOTA性能，并以此为基础打造电商智能体基座，广泛支撑各类电商场景下的Agent应用落地； 5、Agent评测与安全合规：构建贴合实际业务的Agent评测指标与基准，保障在强约束、强对抗环境下的稳定性、安全性与合规性。
课题价值： 1、技术价值：打造通用多模态基座，以模型、数据、算力迭代实现幂律增长，夯实规模化技术底座； 2、业务价值：搭建国际电商大模型底座，以生成式推荐、时序大模型、Agent等驱动GMV与留存，打造高杠杆营收引擎。
Topic Content: In today’s global e-commerce landscape, intelligent systems must operate across increasingly complex and dynamic business environments. Yet existing approaches still face limitations in long-horizon forecasting, cross-modal understanding, and holistic decision-making.This initiative is focused on building a next-generation foundational large model purpose-built for global e-commerce applications. The model will integrate key business dimensions—such as users, products, content, logistics, and inventory—into a unified representation to support deep, context-aware intelligence at scale.Building on this foundation, we are developing a modular, agent-driven architecture that enables advanced capabilities including task planning, tool use, multi-turn reasoning, and real-world environment interaction.Together, these innovations aim to power end-to-end intelligent decision-making across critical e-commerce scenarios, including demand forecasting, traffic optimization, and personalized recommendation systems.
Topic Challenges: 1.Heterogeneous fusion and alignment; 2.Synergy between recommendation LLMs and world models; 3.Tokenizer of recommendation items; 4.Multimodal large models for e-commerce; 5.Agent evaluation, safety, and compliance.
Topic Value: 1.Technical value: Building a general-purpose multimodal foundation to enable power-law scaling through iterative advancements in models, data, and compute, thereby strengthening the infrastructure for scalable AI foundations; 2.Business value: Establishing a global e-commerce foundation model to drive GMV growth and user retention through generative recommendation, time-series large models, and agent-based systems, ultimately creating a high-leverage revenue engine.
