2026-09-01 · OpenAI

Overview

Polimill is building Japan’s next-generation public AI infrastructure, aiming to provide AI capabilities tailored to public-sector needs.

Core technologies

Polimill’s approach relies on two OpenAI components:

  • OpenAI GPT models: used for natural-language understanding and generation to support administrative workflows.
  • Codex: used to assist with development and coding-related tasks, helping speed up implementation.

Use cases for municipalities

The infrastructure is designed to help municipalities work more effectively with administrative knowledge:

  • Searching administrative knowledge: enabling search across administrative information and materials.
  • Using administrative knowledge: applying retrieved information to support administrative work.

Intended impact

Based on the source text, Polimill’s goals include:

  • Improving access to and use of administrative knowledge so local governments can find and leverage needed information more efficiently.
  • Accelerating development by combining GPT and Codex to shorten the time required to build and deliver related tools and capabilities.

Key points

  • Polimill is building Japan’s next-generation public AI infrastructure.
  • The solution uses OpenAI GPT models and Codex.
  • The primary users are municipalities.
  • The main value is better administrative knowledge search and use, plus faster development.
