The 4th Global Digital Trade Expo (GDTE) kicked off on September 25, 2025 in Hangzhou Municipality. Zhejiang Lab (ZJ Lab) made its debut with a series of innovative initiatives, presenting to global attendees its latest advancements and practical explorations in supporting Zhejiang's development as an AI innovation hub to serve global sustainable development.

Focusing on systematized innovation in AI, ZJ Lab unveiled its Haina Central System. In the AI era, models have emerged as the primary users and consumers of data. Driving model-centered data elementization represents a new path of innovation. To enable data elementization, ZJ Lab developed this open AI infrastructure integrating computing power, data, and models, which supports corpus production, model training, and agent development. The Haina Data Network connects over 2,000 open datasets, forming an 18PB+ public corpus pool. Its data production pipeline provides corpus production, deshelling, knowledge graph, and corpus distillation services, ensuring efficient mass production of high-quality corpora for 021 Large Science Model. Equipped with globally leading open-source models, the System offers toolkits for model training and agent development through which models can consume data, and thus innovators are provided with one-stop model training and agent development services. Leveraging the Haina Central System, ZJ Lab develops industry-specific datasets and domain models in fields like materials science, remote sensing, and intelligent manufacturing. These demonstration applications accelerate data elementization, help unlock data value, foster new industries, and drive industrial transformation.

To promote AI + Science, ZJ Lab launched zero2x, an online research and collaboration platform for scientists that integrates computing power, data and models. As a global S&T public good, zero2x offers open scientific services including hypothesis generation, knowledge graph, document retrieval, emulation analysis, and scientist community. The platform incorporates foundation models in geoscience and astronomy, supporting scientific research efforts.
Aligned with global sustainable development goals (SDGs) and adhering to the AI for Good principle, ZJ Lab advances AI and global collaboration through developing global S&T public goods like GeoGPT, launching the Olive Leaf Initiative and the AI Science Frontier Challenge Initiative, and hosting ITU's "Ingenuity Cup" AI and Space Computing Themed Challenge. These efforts further deepen open collaboration with international organizations and professional institutions, supporting international big science programs and UNESCO's International Decade of Sciences for Sustainable Development (IDSSD), and ultimately accelerating SDG achievement. At the GDTE site, numerous international participants expressed a keen interest in the Olive Leaf Initiative. "Many commended our open science initiatives and expressed willingness to seek collaboration," said Anna Stepashkina, a researcher at ZJ Lab, after engaging with multiple visiting groups.




During the Expo, ZJ Lab organized several Showtime salons at its booth, featuring young backbone researchers who presented research findings, shared cutting-edge knowledge, and fostered global partnerships.
"From open-source code in the Internet era to open innovation resources in the AI era, openness remains key to breakthroughs." Upholding the open science philosophy, ZJ Lab is committed to advancing "AI + Science" and "AI + Global Collaboration" initiatives so as to build open innovation infrastructure and develop global S&T public goods, thereby delivering fresh momentum for achieving SDGs.
