Key Requirement
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).
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.
