Polimill builds Japan's next-gen public AI infrastructure with OpenAI, serving 1,050 municipalities

Polimill builds Japan's next-generation public AI infrastructure

Japanese startup Polimill built QommonsAI, a public-sector AI platform using OpenAI's GPT models and Codex. About 1,050 municipalities and 550,000 public employees now use it. The platform standardizes fragmented administrative data—assembly minutes, welfare records, legal documents—into a cross-municipality searchable knowledge base. Development speed increased 3-5x. Polimill's CAIO says GPT's broad familiarity lowers adoption barriers for government staff. The platform includes audit logs and model access controls for security. Polimill aims to evolve QommonsAI into a shared public OS for all Japanese municipalities.
