“As long as financial AI walks close to pain points and lets landed data speak, it can truly become a productivity tool that drives efficiency gains.”

In 2025, as the financial sector's digital transformation moves from "concept exploration" toward "mass deployment," the value yardstick of AI tools has shifted from "leading technical parameters" to "depth of business fit." The "AI Xiaoyan" from CMB Think Tank, jointly launched by China Merchants Bank and Alibaba Cloud, with its precise cracking of investment-research pain points, cross-line landing empowerment, and low-cost implementation path, has become a benchmark case of lightweight financial-AI deployment. It uses solid business data to prove: financial AI needs not chase "big and all," but by walking close to pain points and letting landed data speak, it can truly become a productivity tool that drives efficiency gains.

01 The Essential Contradiction of Financial Investment Research: The Efficiency Deadlock and Transformation Appeal

Traditional financial investment research has long been constrained by three major pain points, becoming the "bottleneck" that limits business-response speed:

First, fragmented information retrieval: researchers must pull research reports, macro data, and corporate financials across multiple systems, and extracting key info often takes hours and is error-prone;

Second, low report-refinement efficiency: manually organizing report summaries and drafting preliminary analysis consumes much repetitive labor, hard to support instant needs like client communication and strategy formulation;

Third, lagging hotspot response: facing market dynamics like Fed rate hikes or sector-policy adjustments, manual analysis needs over 1 hour to form a conclusion, missing the golden window of frontline service.

For a joint-stock bank whose core competitiveness is "service efficiency," this deadlock not only raises internal operating cost, but may also cause missed opportunities in key links like client service and risk assessment. At this point, the value of AI tools is no longer "technical showmanship," but to become a "practical solution" that cracks efficiency problems: this is precisely where AI Xiaoyan comes in.

02 AI Deployment Application: A Lightweight Path of "Collaboration Rather Than Self-Research"

Financial AI deployment often falls into the misconception of "heavy investment, slow output," while AI Xiaoyan walks a low-cost, fast-landing path through the combined strategy of "external-tech collaboration + internal-data empowerment," whose technology-base construction logic is highly worth the industry's reference.

In core technology selection, CMB did not blindly build a full-stack self-research, but deeply collaborated with Alibaba Cloud's Tongyi Qianwen large model, focusing on financial scenarios for dedicated optimization: stripping non-financial noise data from the general model, and strengthening semantic understanding and generation of professional terms like "LPR adjustments" and "NPL ratio," ensuring the professionalism and precision of output. This "borrowing external strength to fix shortboards" model both avoids the huge compute investment needed for hundred-billion-parameter model R&D, and achieves higher fit than general models through scenario-based fine-tuning.

The construction of data fuel relies on CMB's own resource accumulation. "AI Xiaoyan" deeply connects to CMB's largest research-resource platform "CMB Think Tank," integrating core knowledge assets like massive historical research reports and industry data, providing the model a training foundation fitted to financial practice. Meanwhile, its "cloud - edge - terminal" collaboration architecture ensures internal sensitive data never leaves the private cloud, fully meeting the compliance requirement of the Banking Financial-Institution Data Security Management Measures, solving financial AI deployment's "data-security concern."

03 AI Scenario Landing: From Investment-Research Breakthrough to Full-Line Value Penetration

The core competitiveness of CMB Think Tank's AI Xiaoyan lies in crossing from "single tool" to "capability hub": using the investment-research scenario as a breakthrough, it progressively reuses AI capability into core business lines like retail, corporate, and risk, forming a full-chain empowerment closed loop.

In the core investment-research scenario, "AI Xiaoyan" precisely cracks traditional pain points through three functions: the full-site smart Q&A function breaks the deadlock of "cross-system retrieval and information fragmentation," letting frontline staff get integrated multi-source info with one click by inputing a natural-language need; the Chat-report function automates refinement and summary generation of report core viewpoints, replacing manual tedious organizing; the hotspot-focus function real-time captures dynamics like policy changes and market anomalies, quickly generating analysis summaries, letting frontline staff "track hot spots in real time and interpret timely." These functions are not stuck at the pilot stage, but have become daily tools of CMB's internal investment research, significantly shortening the information-acquisition and analysis cycle.

More noteworthy is its cross-line reuse landing effect. Since launch, "AI Xiaoyan" has served tens of thousands of CMB users, providing precise research support for retail-line client communication, corporate-line pre-visit research, and risk-line policy interpretation. For example, corporate-line relationship managers can quickly obtain industry trends and competitor analysis before visiting enterprises; retail wealth managers can use its research results to give clients more professional consulting — achieving the goal of "research creates value, research empowers business."

04 Lessons from the Case: The "Replicable Paradigm" of Financial AI Deployment

The practice of CMB Think Tank's AI Xiaoyan provides three replicable core laws for the AI transformation of small-and-medium banks and joint-stock institutions:

Technology-selection law: don't blindly follow "self-research worship."

For most financial institutions, the investment and output of full-stack self-research large models are hard to match. CMB chose the "external large model + industry fine-tuning" model, focusing resources on core links like "data integration and scenario fit," both lowering R&D cost and achieving fast landing — this "doing some things and not others" strategy is precisely the key to lightweight transformation.

Scenario-entry law: break through from "high-frequency pain points."

AI landing most fears "full sprawl with no real effect"; "AI Xiaoyan" prioritizes solving efficiency problems in "high-value, high-repetition" links like investment research, and after forming a quantifiable value closed loop, extends via capability reuse to the full business chain. This "single-point breakthrough - capability reuse - full-chain empowerment" path maximizes avoiding the risk of "technology idleness."

Value-verification law: bind to "real business needs."

Judging financial AI tools' value should not look at "how big the model parameters," but at "how high the frontline usage rate and how strong the cross-line reuse rate." "AI Xiaoyan" proves with the actual usage data of tens of thousands of users and 26 million hours of labor substitution, ensuring technology truly serves business growth rather than staying at the "technical showcase" level.

Amid today's high GPU compute cost and tightening regulation, the success of CMB Think Tank's AI Xiaoyan is no accident. It pursues no complex technical architecture, nor boasts vain future plans, but precisely steps on the real needs of "investment researchers want efficiency, business staff want support."

This precisely reveals the essence of financial AI deployment: technology is a means, not an end. For financial institutions, truly valuable AI transformation needs no "big and all" strategic declaration, nor "parameter-leading" technical hype; as long as it walks like CMB Think Tank's AI Xiaoyan — close to business pain points, letting landed data speak — it can walk a low-cost, high-fit, replicable field path, which is the core logic of its becoming an industry benchmark.
