Key Requirement
Massachusetts has not enacted a comprehensive AI law: a bill barring discriminatory automated decision systems in employment and other areas (SD.3007) remains in committee, and the state currently relies on Attorney General Campbell's April 2024 advisory that existing anti-discrimination and consumer-protection laws already apply to AI.
Generative-AI providers with over 1,000,000 monthly users must offer a free AI-detection tool and embed a latent provenance disclosure in AI-generated image, video and audio content, plus an optional visible manifest disclosure. Operative August 2, 2026 (delayed from January 1, 2026 by AB 853).
