Key Requirement
Connecticut has not enacted a comprehensive AI law — its high-risk AI bill (SB 2) passed the Senate but died in the House in 2024 and failed again in 2025. Narrow measures apply: a state-agency AI inventory, an automated-decision opt-out under the Connecticut Data Privacy Act, and (effective July 1, 2026) a duty to disclose when personal data is used to train large language models. Existing consumer-protection and anti-discrimination laws may also apply to AI.
Employers must notify employees when AI assists in hiring, reviews, promotions, or discipline, and may not use AI that discriminates against protected classes (including via ZIP-code proxies).
