The 2024 China International Public Security Products Expo (CPSE), the largest global security exhibition, is being held at the China International Exhibition Center in Beijing from October 22–25. With the theme "Digital Intelligence World, Full-Spectrum Security," this year's expo showcases the latest technological products in China's security industry, highlighting their applications and development across various sectors.

Yitu Tech. is showcasing its latest QuestMindTM 4.5 at this year’s expo with the theme "Tianwen Large Model, Expanding the Boundaries of Intelligence." The QuestMindTM 4.5 model represents a significant upgrade in video content understanding, achieving greater precision in security applications.

QuestMindTM 4.5 Upgrade:

Expanding Smart Boundaries

  • Enhanced Video Understanding and Precise Targeting

The QuestMindTM 4.5 model has made significant strides in video content comprehension, not only allowing the model to "see" and "understand" video but also enabling it to quickly recognize small targets and interpret scene relationships. This upgrade greatly enhances the model’s ability to analyze complex scenes, providing precise details of objects and significantly improving control accuracy. The model also supports drone-captured small target video analysis, enabling rapid response and accurate intervention in dynamic, complex environments. This capability is helping to revolutionize urban traffic management and security systems, providing smarter, more efficient support for smart city management.

  • Complex Semantic Understanding for Easier Video Search

QuestMindTM’s integration of natural language and visual search technologies has deepened the connection between complex semantic comprehension and detailed video understanding. The model emphasizes user-centric design, allowing it to understand subtle differences in context and enable precise search capabilities for video content. This advancement enhances the ability to perform complex semantic searches, unlocking a wider range of open-ended video search scenarios. Additionally, the model's natural language interface offers a simple and intuitive user experience, speeding up video content retrieval and accelerating the response time for various business applications.

  • "Xiaoming" Smart Agent Empowers Natural Language Algorithm Composition

In the deployment of large models, converting business requirements into algorithmic tasks is a critical step. The QuestMindTM 4.5 model introduces the Xiaoming AI Agent, which allows users to describe tasks in plain language. Xiaoming then automatically breaks down the task into multiple algorithmic conditions for deployment, democratizing complex algorithm composition that was once the domain of experts. This innovation makes algorithm orchestration much more accessible, simplifying workflows.

  • More Efficient Training and On-the-Fly Tuning

The QuestMindTM 4.5 model has further optimized its algorithm training and iteration process. The minimum number of positive samples required to initiate algorithm iteration has been reduced by 75%, significantly lowering the overall sample size while still achieving the same results. Additionally, the time required for algorithm iteration has been cut down to minutes, with new algorithms going live within days rather than weeks. This efficient iteration capability is critical for responding to emergency situations and government crisis management, enabling smarter, more flexible decision-making in urban governance.

QuestMindTM Wins Industry Recognition

Awarded Multiple Prestigious Industry Honors


In alignment with China’s strategy to develop “new productivity,” the CPSE Expo 2024 hosted its 9th Innovation Product Awards. Yitu's products, which have long been recognized for their excellence in the security sector, were awarded in the expo’s competitive product selection. After rigorous screening by judges and expert evaluations, Yitu won two major awards:

  • QuestMindTM: Innovative Product Grand Prize
  • YITU MindV LVLM Training and Inference Server: Innovative Product Excellence Award

Additionally, Yitu’s "City Eye Perception System Integration Platform" was recognized as a benchmark case in the 2024 AI+ Security Case Evaluation by the China Security and Prevention Products Industry Association, further solidifying Yitu’s leadership in AI-powered security systems.
