Polimill Inc. Selected for Ministry of Internal Affairs and Communications' "Development Demonstration Project for Reliable AI in the Public Sector." Adopting QommonsAI as Verification Platform to Evaluate Domestic LLM "PLaMo" in Real-World Environments of Five Municipalities

Polimill Inc. (Headquarters: Minato-ku, Tokyo / Representative Directors: Ayame Ito and Nonoka Taniguchi, hereinafter "the Company"), a leader in the social implementation of generative AI, is pleased to announce that its demonstration project, "Evaluation and Verification Demonstration of Domestic LLM \"PLaMo\" in the Real-World Environments of Five Municipalities," proposed by the Company as the representative organization, has been selected for the Ministry of Internal Affairs and Communications' "Fiscal Year 2026 Development Demonstration Project for Reliable AI in the Public Sector."

This project received 16 applications nationwide, and as a result of the review, 4 projects, including the Company's, were selected.

(Announced by the Ministry of Internal Affairs and Communications on June 8, 2026)

Background: The Challenge of "Fairness in Judgment" in Frontline Operations Facing Residents

The use of generative AI is rapidly expanding in administrative settings for tasks such as document creation and inquiry response. However, ensuring "reliability," including the accuracy of responses and the secure handling of information, remains a common challenge in operations directly linked to resident services.

In particular, municipal employees are required to make various judgments daily in situations directly impacting residents' lives (welfare, health, administrative procedures, etc.). Yet, there are cases where judgment standards vary depending on the 담당자 (person in charge), or less experienced staff hesitate in making appropriate judgments.

Especially in the "SoE (System of Engagement)" domain, which involves engaging with each resident's situation, operations are extremely important for municipalities but also tend to become personalized. If AI can be utilized as a "tool to organize the basis for judgment and support fair and impartial initial decisions" in this domain, it can contribute to both improving the quality of resident services and reducing the burden on staff.

The use of generative AI developed by domestic companies is attracting attention as "reliable AI" that can enable such responses. This demonstration project starts by verifying the characteristics, application areas, and implementation methods of domestic AI within the actual operations of municipalities, rather than theoretical evaluations.

Objective of This Demonstration: To Verify Characteristics, Application Areas, and Implementation Methods of Domestic AI in Actual Operational Environments

In this demonstration, we will evaluate and verify the domestic LLM "PLaMo" (provided by Preferred Networks, Inc.) in comparison with major overseas LLMs.

The evaluation will cover a wide range of aspects, including response quality, accuracy, and safety. The aim of this demonstration is to evaluate and verify the characteristics, application areas, and implementation methods of domestic AI through its utilization in actual administrative operations.

We will utilize "QommonsAI" (CommonsAI), an AX platform for administration provided by our company to municipalities nationwide, as the foundation for the verification. By having five municipalities conduct verification in a common environment, we will achieve a fair comparison under uniform conditions.

Demonstration Name

Evaluation and Verification Demonstration of Domestic LLM \"PLaMo\" in the Real-World Environments of Five Municipalities

AI Under Verification

PLaMo 3.0 Prime (Provided by Preferred Networks, Inc.)

Verification Platform

QommonsAI

Participating Municipalities

Himeji City, Amagasaki City, Kasai City, Kato City, Taka Town (Five municipalities in Hyogo Prefecture)

* This demonstration aims to identify the characteristics and application areas/methods of each LLM in administrative work and is not intended to judge the superiority or inferiority of LLMs.

Anticipated Demonstration Use Cases ("Judgment Support" in the SoE Domain)

For the verification in real-world environments, we anticipate various scenarios related to resident services and internal municipal operations, with the cooperation of each municipality.

In all these operations, AI will not make the final decision. The purpose is to ascertain whether AI can support staff judgments and operations and provide organized, easy-to-understand explanations of the basis for them within the diverse operations of each municipality.

Target Operations Anticipated by Each Municipality

Himeji City [Judgment Operations in Welfare Field]

Can it clearly organize and present the basis for judgment in accordance with established standards?

Amagasaki City [Multicultural Coexistence Window Operations]

Can it provide stable responses to everyone without bias in output due to differences in individual attributes, etc.?

Kasai City [Accounting Operations]

Can it accurately organize and guide the procedural flow based on regulations and manuals?

Kato City [Support for Developing Operational Manuals]

Can it support the creation of manuals for various procedures and improve the efficiency of staff operations?

Taka Town [Judgment Operations in Child-Rearing Support Field]

Can it clearly organize preliminary judgment proposals in accordance with municipality-specific standards?

Hyogo Prefecture Comment

We consider it an extremely valuable opportunity and have high expectations to participate in this demonstration using domestic LLMs, with Polimill Inc. and five municipalities in Hyogo Prefecture as partners, using their respective municipal operations as use cases. We feel a great significance in contributing to both "providing fairer and more impartial resident services" and "improving the efficiency of municipal operations" through this demonstration. By accumulating the knowledge gained from the demonstration in five municipalities with different scales and operational characteristics, we aim to create best practices for the utilization of reliable AI not only within Hyogo Prefecture but also for municipalities nationwide, thereby further deepening administrative DX.

Riku Okada, General Manager, AI Products & Solutions Business Division, Comment

We believe that evaluating our PLaMo 3.0 Prime in municipal operations through the demonstration conducted by Polimill Inc. in five municipalities is a valuable opportunity to objectively grasp the capabilities and challenges of domestic LLMs. PLaMo 3.0 Prime has been developed with a focus on Japanese language use, anticipating a wide range of applications, from situations requiring complex reasoning in practical operations to those demanding rapid responses. Based on the insights gained from this demonstration, we will further improve PLaMo as a support tool for staff working to improve municipal operational efficiency and resident services.

Polimill Inc. Representative Directors Ayame Ito / Nonoka Taniguchi Comment

The discussion surrounding AI utilization in administration is shifting from "whether it can be used" to "for what and how it should be used." However, there are still few demonstrations that attempt to answer this question using actual operational data and on-site context.

What we have consistently focused on is the social implementation of AI. Our role, as we see it, is not just to evaluate the potential of technology, but to translate it into a form that functions in real-world settings and directly impacts the quality of resident services.

What makes this demonstration different from previous ones is our focus on "real-world environments." The significance of this demonstration lies in verifying how AI functions within the actual operational flows of five municipalities in tasks directly related to residents' lives, such as welfare and child-rearing support, where the basis for judgment is questioned.

The results of how PLaMo performs reasoning with Japanese administrative documents could become public knowledge for considering the social implementation of domestic AI. We will steadily build that knowledge together with the five municipalities.
