Note: The AI & Open Government workshop (AIOG) focuses on how modern AI tools and techniques, including Large Language Models (LLMs), can support government accountability and transparency by improving public access to government records and enabling more reliable and compliant disclosure processes. In many jurisdictions, open government and access to information laws such as Freedom of Information (FOIA) and Access to Information (ATI) require large-scale public disclosure of government records, resulting in massive, multimodal data collections whose complexity increasingly challenges both legal compliance and technical processing. At the same time, governments face strict legal obligations to disclose information within statutory deadlines, while protecting sensitive and personal information. The workshop addresses two key perspectives: (1) AI for citizens--tools and techniques for improving search, exploration, and understanding of public government information; (2) AI for governments--assisting in accessibility, pre-processing, metadata enrichment, retrieval, filtering, and protecting sensitive information consistent with public disclosure laws
