- 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;
- 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;
- 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;
- 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;
- 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:
- 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;
- 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:
- Heterogeneous fusion and alignment;
- Synergy between recommendation LLMs and world models;
- Tokenizer of recommendation items;
- Multimodal large models for e-commerce;
- Agent evaluation, safety, and compliance. Topic Value:
- 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;
- 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.
