Revise election laws regarding disclosure requirements for the use of AI in elections
Montana bars people and groups working in an official election capacity from paying for or sponsoring an election or electioneering communication they know, or should know, is a deepfake of a candidate or party on the ballot, within 60 days before voting begins, unless it carries the disclosure 'This (image/audio/video/multimedia) has been significantly edited by artificial intelligence and depicts speech or conduct that falsely appears to be authentic or truthful.'

Limit government use of AI systems
HB 178 (Chapter 427 of 2025) limits government AI use. State and local government entities and state officers may not use an AI system for cognitive behavioral manipulation, to classify people in ways that cause unlawful discrimination or disparate impact, for a malicious purpose, or to surveil public spaces except to find a missing, endangered or wanted person or as the facial surveillance law allows. AI-produced material published without review by a trained human must be labeled, and public-facing AI interfaces disclosed.

Generally revise laws related to crimes against children
Montana's HB 82 (Chapter 102 of 2025) brings AI-made child sexual abuse images into the offense of sexual abuse of children. Knowingly possessing computer-generated child pornography is now covered.

Agencies may use facial verification only under a written use and privacy policy, with notice, vendor retention limits and human review training. People harmed may sue.
