Transforming Call Center Operations with Mini-RAG

In a groundbreaking move for the call center industry, KaiTaku Inc., headquartered in Shinjuku, Tokyo, has introduced a new feature called Mini-RAG for its AI solution, Spaden. Officially launched on December 16, 2025, Mini-RAG aims to address critical challenges faced by call center managers, namely issues related to education, knowledge dependency, and quality variability.

The implementation of this feature promises to revolutionize the way call centers handle inquiries by allowing artificial intelligence to retain and reference corporate manuals, FAQs, and operational rules comprising hundreds of thousands of characters. This capability enables the AI to make real-time decisions during calls. With a remarkable accuracy rate of over 99.5% achieved in NIAH tests, Mini-RAG allows for 'AI telephony' that can be utilized on the frontlines without needing to train or escalate inquiries to human operators.

Addressing Industry Challenges

As call centers grapple with severe staff shortages, the deployment of AI has become increasingly common. However, many frontline managers have reported significant limitations:

• - Lack of Understanding: Traditional AI systems often understand only portions of manuals, leading to complex queries being rapidly forwarded to humans.
• - Low Automation Rates: Many AI callbots merely respond to FAQ-like questions, lacking the capability to mimic a veteran operator’s nuanced decision-making process.
• - Ongoing Training Needs: Continuous supervision and updating of educational materials remain burdensome for managers, keeping operational costs high.

How Mini-RAG Changes the Game

Unlike traditional AI systems that only reference singular FAQs, Spaden with Mini-RAG achieves the following:

1. Comprehensive Knowledge Retention: By fully encompassing huge amounts of operational knowledge, Mini-RAG generates contextually accurate responses instead of relying solely on keyword searches.
2. Automated Complex Judgments: It autonomously resolves intricate business rules spanning multiple manuals, making decisions like 'If A and B then C' without disruptions.
3. Zero Training and Handover Time: Simply feeding operational guidelines into the AI enables instant deployment, drastically reducing weeks or months of training typically required for new employees.

Key Features of Mini-RAG

1. Instant Decision-Making: The AI memorizes vast amounts of business knowledge, enabling it to respond to inquiries that require complex reasoning, such as, 'That’s A, but in case of condition B, it becomes C.' This automates responses where human discretion was previously necessary.
2. High Accuracy Ratings: With a proven track record of surpassing 99.5% accuracy, the AI mitigates quality variations and ensures uniform service across different operators.
3. Maintenance-Free Operation: No ongoing supervision or training is needed; just introduce the manuals to the AI, and it can achieve operational efficiency even in environments with high employee turnover.

Future Developments

Moving forward, KaiTaku aims to enhance its platform built on Mini-RAG by focusing on sector-specific models tailored for finance, human resources, real estate, and more. They also plan to leverage call data for operational improvements and performance visualization.

Spaden aspires to be more than just an automated response tool; it strives to become an indispensable AI agent for call center leaders, allowing them to streamline processes efficiently.
