For details on each update, please see the following feature articles.
7 Highlights of This Update
① Integration of 12 Models from 4 Major Companies - An Era Where Local Governments Choose the "Optimal AI"
We have consolidated 12 carefully selected models from the world's top 4 cutting-edge companies: OpenAI, Anthropic, Google, and Preferred Networks, into a single platform. With three classes—Frontier, Standard, and Basic—you can optimally select the AI according to the complexity of your tasks. 7 of the 12 models operate in the domestic region, and the purely domestic LLM "PLaMo 2.2 Prime" is also selectable. The era of worrying about "which AI to use" is over.

② Equipped with GPT-5.4 in the Domestic Region - 300 Million Tokens Free Monthly, Dramatic Improvement in Form Reading Accuracy
Speedily equipped with OpenAI's latest frontier model "GPT-5.4" in the domestic region. We offer 300 million tokens for free per month per local government. With "Full Resolution Image Processing" that processes high-resolution images of over 10 million pixels without compression, the accuracy of reading paper documents and forms has dramatically improved. Response errors have been reduced by 18% compared to conventional models. We will fundamentally eliminate the stress of "insufficient accuracy."

③ Simultaneous Integration of 3 Image Generation AI Models - Entering an Era Where They Can Be Used Directly for Printing with 4K Support
Equipped with 3 models: "Nano Banana 2," "Nano Banana Pro," and "GPT Image 1.5." Nano Banana 2 supports 4K resolution, multi-language text rendering, and automatic addition of SynthID digital watermarks. AI generates draft PR posters and flyers in seconds. The era has arrived where tasks previously outsourced to design companies can be completed within the government office.

④ Equipped with 3-Layer Defense: Automatic Detection of Personal Information, Prohibited Word Blocking, and Detection Logs - Realizing "Want them to use it, but won't let info leak" Information Governance through the Power of AI
Equipped with a 3-layer defense consisting of "Automatic Personal Information Detection," which automatically detects, warns against, and blocks names, addresses, My Number, etc.; "Prohibited Word Expansion," allowing administrators to set over 100 words; and "Detection Logs," which allows viewing of all histories. We confront head-on the anxieties of administrators who say, "I want them to use AI, but I'm afraid of information leaks."

⑤ Equipped with Quantitative Visualization of Business Reduction Effects, Input/Output Log Management, and Super Administrator Privileges - Moving to an Era of "Proving the Effects of Generative AI with Numbers"
Equipped with an "Effect Measurement Dashboard" that visualizes usage frequency, utilization status by department, and estimated time saved, along with automatic CSV output of input/output logs, and automatic generation of monthly reports. These can be used as quantitative evidence in assembly reports and budget requests. We support continuous PDCA, ensuring it doesn't just end with "implementation."

⑥ Equipped with "Deep Research" Function - Collaboration with Administrative Knowledge is Also Possible. Entering an Era of Automating the Entire Research Process
It autonomously iterates the cycle of breaking down questions → formulating search plans → Web searching → scrutinizing information → re-searching → generating reports, automatically creating research memos with citations, comparison tables, and issue summaries. It can also be used in combination with cross-sectional searches of administrative knowledge across municipalities nationwide and internal RAG, automating the entire research process for preparing assembly answers and policy planning.

⑦ "New Hierarchical Structure" Equipped in Private Knowledge - Fundamentally Changing AI Response Accuracy
Systematically organizes and manages internal documents with up to 5 tiers of folder management and 3 levels of role permissions: Super Administrator / Administrator / Member. We provide standard free RAG storage of 100GB for basic municipalities and 300GB for broad-based municipalities, allowing the AI to instantly convert uploaded documents into high-performance RAG.

⑦ A Single AI Crosses Administrative Knowledge of All Tiers
QommonsAI's cross-sectional search of administrative knowledge has traditionally included public documents such as assembly minutes of local governments nationwide, providing a mechanism for shared use across tenants.
With this expansion, the target scope covers all the following tiers.
Central Ministries and Agencies: Policy documents, notices, guidelines, council materials, white papers, etc., published by each ministry and agency.
Prefectures: Assembly minutes, council minutes, planning/policy documents, etc., of all 47 prefectures.
Municipalities: Assembly minutes, administrative plans, ordinance-related materials, etc., published by basic municipalities nationwide.
This information is independently collected and automatically updated by Polimill Inc., with zero operational burden on the local government side. You can access tens of millions of administrative documents from the first day of implementation.

Message from Polimill
QommonsAI is not just a tool for business efficiency. In our busy daily lives, we want it to be a work partner that makes you feel, "We can change the community with our own power."
This major update was born from continuing to face the essential challenges behind the "troubles" on the ground. We carefully receive each and every voice, continuously refining it until you feel, "I'd be in trouble without this." The integration of 12 models, Deep Research, strengthening information governance—all of these are features born to turn the "I wish we could do this" on the ground into "We can do this."
Believing that enriching the daily lives of local government employees, even a little, leads to the happiness of the residents beyond that, and that these things lead to the enrichment of this country, we will continue to create.
Message from COO Nonoka Taniguchi
With this update, the foundation we envisioned as necessary for generative AI for public administration has begun to take shape. However, this is just the prologue. Our endeavor as an OS provider company that updates the entire business operations of the public sector starts here. From April to August 2026, we will release new AI Native products of the QommonsAI series in rapid succession.
In addition to the government-exclusive app store "Qommons ONE," conversational app generation "Qommons Studio," no-code AI agent construction "Qraft," inter-municipal knowledge network "Qord," and public-private matching "Qonnect," we will sequentially deploy "Qommons Journal," a Web media serving as the information infrastructure for local government employees, "Qompass," a nationwide municipal transparency register allowing the choice to disclose AI usage to residents, "QUSTOS," a national disinformation and misinformation portal, and "Quester," a gamified human resource development platform.
Rewriting the "way of working" itself for local governments—the largest software update in the history of Japanese public administration begins.
