As states continue to debate and pass AI regulation, Connecticut has adopted a targeted approach—imposing requirements for certain high-risk uses rather than establishing a comprehensive governance regime. Connecticut Governor Ned Lamont signed SB 5, “An Act Concerning Online Safety,” into law on May 27, 2026, enacting one of the most wide-ranging state AI laws to date. SB 5 establishes requirements across multiple high-stakes regulatory areas, including frontier AI models, AI companions, automated employment-related decision technology (AEDT), and content provenance. The law creates several distinct compliance frameworks, with provisions taking effect between October 2026 and January 2028. This alert summarizes key provisions and outlines recommendations for developers, deployers, and providers of AI services.
Effective October 1, 2026
SB 5 creates disclosure requirements for entities that offer AI technologies to Connecticut consumers on a subscription basis (“subscription-based providers”) before they enter into or renew a subscription with a consumer.
Before collecting payment, the provider must give the consumer a written notice disclosing the key subscription terms, and the consumer must confirm acceptance in writing.
The written notice must include the following:
Violations constitute unfair or deceptive trade practices, enforceable solely by the Attorney General.
Effective October 1, 2026
SB 5 requires that frontier developers comply with whistleblower protections and large frontier developers must also implement internal risk reporting channels.
SB 5 uses the same thresholds adopted under the California and New York frontier AI laws, defining a “frontier developer” as a person doing business in Connecticut that trains foundation models using more than 10²⁶ floating-point operations (FLOPs). Frontier developers with more than $500 million in annual gross revenues are classified as “large frontier developers” and are subject to additional requirements.
Like California’s SB 53, Connecticut’s SB 5 extends whistleblower protections to employees of frontier developers who report catastrophic risk concerns. New York’s Responsible AI Safety and Education (RAISE) Act, by contrast, does not include comparable whistleblower protections. Unlike the California and New York frontier AI frameworks, SB 5 does not require developers to implement safety frameworks and issue transparency reports.
The Attorney General may bring actions seeking civil penalties of up to $1,000 per violation, as well as injunctive or equitable relief.
Effective January 1, 2027
Connecticut joins a growing number of states that have passed laws regulating AI companions, including California, Idaho, Iowa, Georgia, New York, Oregon, and Washington, and follows the general framework of these laws with requirements for AI disclosures to users, crisis intervention protocols, and protection for minors.
SB 5 defines AI companions as AI systems with natural language interfaces that provide adaptive, human-like responses to user inputs and can sustain relationships across multiple interactions. The definition excludes several specialized tools, including customer service chatbots, narrowly tailored educational tools, and voice-assistant-only devices. SB 5’s scope aligns closely with the definitions outlined in California, Georgia, New York, Oregon, and Washington’s AI companion laws, all of which focus on AI systems that are designed to simulate human-like connection and are capable of sustaining relationships across multiple interactions. Idaho and Iowa take a broader approach, regulating “conversational AI services” without requiring a sustained-relationship element, potentially bringing a wider range of chatbot products within their scope.
Operators of AI companions must implement evidence-based protocols to detect user expressions of suicide risk, self-harm, or imminent physical violence and prevent the generation of outputs that encourage such conduct. If such user expressions are detected, operators must refer the user to appropriate mental health resources such as the 9-8-8 National Suicide Prevention Lifeline. If such user expressions continue after an initial referral, operators must refer the user to mental health services in a manner consistent with clinical best practices. The operator must also implement reasonable measures to prohibit the AI companion from claiming it is human.
Operators must publicly post their safety protocols on their website.
If an AI companion could cause a reasonable individual to believe that they are interacting with a human being, the operator must issue a clear and conspicuous notice to the user that they are communicating with an AI companion, either:
Connecticut’s disclosure requirements fall on the stricter end of the spectrum among state companion chatbot laws. Like Washington and Georgia, Connecticut requires disclosures at least once per hour for minors and once every three hours for adults. California and Oregon, by contrast, require disclosures only once every three hours for minors and an initial disclosure for adult users with no prescribed recurrence. New York requires disclosure to all users at the beginning of any interaction, and at least every three hours for continuing interactions, but has no additional disclosure requirement for minors.
When an operator knows or has reason to believe a user is under 18, the operator must institute measures to prevent the AI companion from:
Operators must also make screen time management and account settings tools available to minor users and their parents or legal guardians.
Violations constitute unfair or deceptive trade practices enforceable solely by the Attorney General.
Effective October 1, 2026 (requirements operative October 1, 2027)
SB 5 defines “Automated Employment-Related Decision Technology” (AEDT) as any technology that processes personal data and generates outputs, including, but not limited to, a rank, score, classification, or recommendation, constituting a substantial factor used to make or materially influence an employment-related decision to hire, fire, promote, discipline, renew employment, or select an individual for training. “Substantial factor” means a factor, including a ranking or score, that meaningfully alters the outcome of an employment-related decision concerning an individual in Connecticut. The requirements apply to AEDT that is developed and/or deployed in the state on or after October 1, 2027.
SB 5’s AEDT provisions are consistent with a growing body of comparable state and local frameworks for the use of AI to make consequential decisions. California’s amended Consumer Privacy Act regulations and New York City’s Local Law 144 establish similar developer and deployer obligations, as does Colorado’s SB 189, which repealed and replaced the Colorado AI Act and takes effect January 1, 2027. While the California and Connecticut laws apply to multiple types of consequential decisions, Connecticut’s, like the New York City law, applies only to employment-related decisions.
SB 5 also amends Connecticut’s employment discrimination statute to clarify that use of AEDT is not a defense against a discrimination complaint. The court may consider evidence of anti-bias testing or similar proactive efforts that were used to avoid discriminatory practices.
Violations are enforceable solely by the Attorney General. For violations occurring on or before December 31, 2027, the Attorney General may issue a notice of violation with a 60-day cure period before initiating enforcement if the Attorney General determines a cure is possible.
Effective October 1, 2026
SB 5 establishes AI content provenance requirements for “covered providers,” which are defined as persons who create a generative AI system with over one million monthly users that is publicly accessible to consumers in Connecticut. Connecticut’s provenance requirements broadly track California’s AI Transparency Act, which similarly requires covered providers (defined in the same way) to embed provenance data in AI-generated content and use tamper-resistant methods consistent with industry standards. California goes farther than Connecticut, however, by requiring covered providers to make a free AI detection tool publicly available to users.
Under SB 5, covered providers must:
Provenance data need not include any information relating to an identified or reasonably identifiable individual, and trade secrets are exempt.
Violations are enforceable solely by the Attorney General.
Effective January 1, 2028
SB 5 establishes online safety obligations for “covered platforms,” defined as platforms that, as a significant part of their services, recommend, select, or prioritize user-generated media content. “Covered operators” are defined as operators who operate or provide covered platforms, excluding government agencies.
SB 5 includes several provisions related to minors’ use of covered platforms, including:
By March 1, 2028, and annually thereafter, covered operators must publicly disclose, for the preceding calendar year, the total number of covered users, the portion of the total number of users that provided parental consent and for whom the default settings were enabled, and average daily usage broken down by age and hour.
Violations constitute unfair or deceptive trade practices under Connecticut law.
SB 5 contains several additional provisions addressing workforce development, education, economic development, and public-sector AI use. Among other things, the law establishes the Connecticut AI Academy, creates multiple AI-related advisory groups and working groups, directs state agencies to inventory and assess certain AI systems, and creates programs and studies relating to AI workforce development, economic competitiveness, and AI adoption. The law also directs the Commissioner of Economic and Community Development to develop a plan for an AI regulatory sandbox program, which would allow applicants to temporarily test AI products under reduced licensure and regulatory requirements.
Companies with operations or customers in Connecticut should consider the following priorities:
