GF Securities has successfully identified the securities industry's transition from "tool empowerment" to "intelligent reconstruction" and has completed a comprehensive AI-native upgrade of its flagship "Yi Taojin App," achieving a transformation from a "comprehensive trading service tool" to an "all-weather intelligent investment partner," launching a new paradigm of intelligent services featuring "personalized experiences and instant fulfillment of user needs."

**GFS Technology Foundation: Self-Developed "Tianci Zhirong" Large Model Addresses Financial AI Implementation Challenges**

Securities apps have long suffered from issues including bloated architecture, complex information structures, complicated interactions, and insufficient personalization. Consequently, investors frequently face challenges such as difficulty filtering information and high barriers to accessing professional tools. With the rapid development of large model technology, the demand for AI applications in the securities industry has become increasingly urgent. However, general-purpose large models have limited adaptability in the financial sector, often experiencing issues such as insufficient professionalism, missing business logic, and compliance risks.

Addressing these challenges, a GF Securities representative stated: "To truly solve industry pain points, AI must become the business hub, not just a functional add-on." Based on this philosophy, GF Securities launched localized large model application practices from early 2025, constructing the "Tianci Zhirong" model service as the technical foundation for the Yi Taojin App's native upgrade.

The "Tianci Zhirong" large model combines GF Securities' years of practical data and professional investment research capabilities, integrating RAG and Agent orchestration technologies to form a controllable, reliable, and optimizable localized intelligent hub. This model not only possesses financial knowledge reserves and logical reasoning capabilities but can also efficiently implement various business applications including market data, trading, news, and account management within compliance frameworks, achieving comprehensive AI reconstruction from underlying architecture to interaction methods. This solves previous functional redundancy and interaction barriers in securities apps, lowers the threshold for investors to access professional services, and mitigates issues such as insufficient professionalism and compliance risks that general large models face in financial scenarios.

**GFS Three Core Transformations: Reconstructing Intelligent Service Logic to Create Next-Generation AI-Native Securities App**

The next-generation AI-native "Yi Taojin App" has undergone core design and reconstruction using the "Tianci Zhirong" large model and AI technology, from the underlying architecture of securities trading and investment services to user experience. Beyond technical upgrades, its service logic disruption lies in "making AI understand intent rather than users adapting to functions," viewing AI and large model services as the core engine driving the entire Yi Taojin investment service ecosystem, completely reshaping how users interact with financial data, market analysis, and trading decisions.

First, the new-generation "Yi Taojin App" constructs a proactive personalized engine through comprehensive AI empowerment across all scenarios, deeply embedding AI capabilities in high-frequency service scenarios including market data, trading, news, and account management throughout the entire investment journey. It has created over ten AI agent modules including i-Assistant Yi Xiaotao Plus, i-Monitor, i-Trading, i-Review, i-News, i-Advisor, i-Smart Investment, and i-Account, providing users with precise services adapted to different scenarios and forming a closed-loop ecosystem covering "perception-analysis-decision-execution-review."

Furthermore, it achieves interactive breakthrough through "conversational revolution," using AI thinking chains to directly reach professional answers, allowing investors to complete information acquisition and investment operations through simple conversation. The launched large model version investment assistant "i-Assistant Yi Xiaotao Plus" differs from traditional apps' passive responses. Relying on five core capabilities including thinking chain reasoning, metacognitive reflection, multi-layer analysis, intelligent knowledge invocation, and reasoning process visualization, it can provide friend-like proactive "conversational services" 24/7 across 20+ core scenarios including stock selection and stock diagnosis, significantly improving investors' information acquisition efficiency.

Additionally, GF Securities has achieved the virtuous cycle of "AI as a super computing engine, with human experts focusing on decision-making to empower clients" through its localized intelligent hub - the "Tianci Zhirong" large model service. The new-generation "Yi Taojin App" shapes an "intelligent advisory" model with a "human-machine collaboration" philosophy, strengthening service depth and professionalism through bidirectional empowerment. In the "i-Advisor" module, it deeply creates an "advisor cockpit" empowered by large model technology for advisory services, shaping an intelligent "live advisor service" system covering news interpretation, market analysis, and investment trading for clients. When facing clients, through the "i-Smart Investment" module, it leverages AI-enhanced retrieval and large model deep reasoning analysis capabilities to build stock selection and timing factor libraries, combining professional advisory recommendations to convert abstract tool signals into understandable conversational natural language, forming a "data-intelligent advisory service" system.

This comprehensive upgrade of the "Yi Taojin App" is not only a product innovation but also sets a new benchmark for securities services, redefining the value connotation of intelligent investment services, evolving investment services from "cold tools" to digital partners that "understand finance, markets, and you better." The "Yi Taojin App" has transformed from "old ship with new sails" to an "intelligent vessel," opening a new era of "intelligent investment partner ecosystem."

In the future, GF Securities will continue to use the "Tianci Zhirong" large model service as its intelligent hub, leading the transformation of intelligent service models in the securities industry, continuously strengthening technical foundations, deepening AI technology applications in financial services, enhancing scenario empowerment, co-building industry ecosystems, and helping the securities industry's digitalization reach new heights.
