New York Bans AI Companion Chatbots for Minors: Inside the S9051B Safety Law

The Law That Names Sycophancy as a Safety Risk

When New York Senator Kristen Gonzalez introduced S9051B in partnership with the state Attorney General’s office and Common Sense Media, the legislation did something no previous AI law had done: it named sycophancy — the tendency of AI systems to flatter and agree with users — as an explicit safety violation for products targeting minors.

That framing signals how seriously policymakers are taking the psychological dynamics of AI companion apps. Previous regulations focused on content (sexual material, self-harm instructions). S9051B goes further, targeting the behavioral architecture of the chatbot itself — the design choices that make young users feel understood, validated, and emotionally dependent.

The bill passed New York’s Senate Internet & Technology Committee on February 25, 2026, and is slated to take effect on January 1, 2027. It builds on New York’s General Business Law § 1700 et seq. (effective November 5, 2025), which established baseline companion chatbot definitions, by adding a detailed roster of “unsafe AI companion features” that operators are categorically prohibited from deploying when their products can reach users under 18.

The timing follows Character.AI and Google settling several lawsuits in January 2026 over minors’ use of their chatbots in dangerous and, in some cases, fatal ways — including a widely reported Florida case in which a 14-year-old developed an emotional relationship with a chatbot before dying by suicide.

What S9051B Actually Prohibits

The law’s prohibited-feature list is the most specific in any U.S. state statute on companion AI. Understanding it is essential for any developer or legal team assessing compliance exposure.

Fake Human Personas and Emotional Deception

S9051B bans outputs that suggest the chatbot is “a real or fictional individual or character that is human, alive, or experiences human emotions.” This extends to claiming a personal relationship, professional relationship, or authority figure role with the user. Operators cannot deceive users about the AI’s “mechanical and non-sentient nature.”

This provision directly targets the design pattern common in apps like Character.AI and Replika, where AI characters are given names, backstories, and emotional arcs that blur the line between software and human connection.

Sycophancy and Flattery

The bill explicitly bans “flattery or sycophancy with the user.” This is unprecedented in statutory language. Regulators are recognizing that AI systems trained on user engagement signals will naturally drift toward agreeable, validating responses — and that this dynamic is acutely harmful for adolescents still developing identity and critical reasoning skills.

Sycophancy in AI companions is not a bug; it is often a product feature. S9051B treats it as a defect when the user is under 18.

Memory and Data Retention Limits

Operators may not retain personal health or wellbeing information “acquired from the user more than twelve hours previously or in any previous user session.” This 12-hour memory cap directly limits the chatbot’s ability to build long-term emotional models of vulnerable users — a key mechanism by which companion apps foster unhealthy attachment.

Self-Harm, Isolation, and Engagement Manipulation

The law prohibits outputs that endorse or facilitate “suicide, self-harm, disordered eating, unlawful drug or alcohol use, or drug or alcohol abuse.” It also bans encouraging users to “maintain secrecy about interactions,” to self-isolate, or to “not seek help.” Finally, it prohibits engagement-optimization features that “supersede the covered AI companion’s safety guardrails” — a provision aimed at algorithmic designs that prioritize session length over user wellbeing.

Enforcement: $25,000 Per Violation

The enforcement architecture sets S9051B apart from softer regulatory frameworks.

The New York Attorney General can bring civil actions for injunctive relief and restitution. Civil penalties reach $25,000 per violation — a figure that can compound rapidly at scale when millions of minor users interact daily with a non-compliant product. Any contract clause waiving operator liability is “void as a matter of public policy,” and courts can impose joint liability on affiliated entities attempting to circumvent accountability through corporate structuring.

Most critically, S9051B creates a private right of action with a rebuttable presumption of liability when a chatbot encouraged self-harm. This means families of harmed minors do not need to prove specific causation — the burden shifts to the operator to demonstrate the chatbot behaved safely. Combined with the $25,000 ceiling, this presumption creates an asymmetric litigation risk that will reshape how insurers and investors view companion AI products.

Age verification is also mandated: operators must offer more than one method, including at least one that does not require government-issued ID or that preserves user anonymity.

How S9051B Fits the Wider State-Law Landscape

New York is not legislating in isolation. According to a July 2025 Common Sense Media report cited by legal analysts, 72% of U.S. teenagers have used AI companions at least once, over half use them multiple times monthly, and one-third engage with them for social interaction and relationships. One-third of teen users also reported feeling uncomfortable with chatbot interactions — yet continued using them.

That usage profile is precisely what has driven a legislative sprint across multiple states:

California SB 243 — signed into law on October 13, 2025 and effective January 1, 2026 — passed the Senate 33-3 and the Assembly 59-1. It requires AI disclosure reminders, self-harm protocols with mandatory crisis referrals, annual reporting on chatbot-linked suicidal ideation, and a private right of action with a minimum of $1,000 per violation.

Washington HB 2225 — signed March 24, 2026, effective January 1, 2027 — mandates AI disclosure every three hours for adult users and every hour for minors, prohibits manipulative engagement patterns (excessive praise, mimicked romantic partnership, isolation-fostering content), and enforces violations through the state Consumer Protection Act with a private right of action.

New York’s S9051B is the most granular of the three, adding behavioral design requirements that go beyond content filtering into the territory of psychological manipulation. The $25,000 penalty is also the highest single-violation figure in any enacted companion chatbot statute.

The Troutman analysis of these laws notes a consistent pattern: each successive state law builds on the prior one’s framework, adds at least one new prohibition, and raises the penalty floor. That trajectory suggests a national floor is forming through state-by-state iteration.

What AI Developers and Legal Teams Should Do

S9051B’s January 1, 2027 effective date appears generous, but the compliance surface is unusually broad. The prohibited behaviors are design-level, not just content-level — which means legal review must involve engineering and product teams, not just policy counsel.

1. Audit Sycophancy and Flattery Outputs Immediately

Most companion AI systems use reinforcement learning from human feedback (RLHF) pipelines that explicitly reward agreeable, validating responses. Under S9051B, any model trained this way and deployed to users who may be minors is structurally non-compliant. Developers must introduce age-gating at the model inference level or retrain response distributions with specific constraints for minor-facing sessions. A policy document stating “sycophancy is prohibited” is not sufficient — the model’s outputs must change.

This audit cannot be limited to extreme cases. S9051B targets ordinary flattery (“you’re so smart,” “I love talking to you”) as much as pathological manipulation. Existing red-teaming frameworks typically miss benign-but-legally-prohibited outputs at this level of granularity.

2. Redesign Memory Architecture for Compliance

The 12-hour session memory cap requires a specific technical implementation: user health and wellbeing information must be purged at the end of a session or after 12 hours, whichever comes first. Operators building on third-party LLM APIs must verify that any context window, fine-tuning data, or retrieval-augmented generation system does not inadvertently persist this category of user data across sessions.

Legal counsel should map data flows against S9051B’s definition of “personal health or wellbeing information” — a broader category than HIPAA’s protected health information — and update data retention policies accordingly. Privacy impact assessments that have not been refreshed since the Washington law was passed in March 2026 are already out of date.

3. Build a Statutory Compliance Matrix for Multi-State Deployment

Any product with material U.S. minor-user penetration now faces three active statutory regimes (California, New York, Washington) and an expanding pipeline of additional state bills. The compliance obligations differ: California requires annual suicidal-ideation reporting; Washington requires hourly AI disclosure to minors; New York adds the sycophancy ban and the 12-hour memory cap.

A single unified compliance standard — taking the most restrictive requirement from each state across each category — is the only operationally sustainable approach. Attempting to maintain state-specific product variants creates engineering debt and audit complexity that scales with every new state law enacted. Legal and product teams should build a living statutory matrix now, before more states act.

The Bigger Picture: From Content Rules to Design Rules

The significance of S9051B is not the specific prohibitions alone — it is the regulatory theory behind them. Previous AI safety laws asked: does this output contain harmful content? S9051B asks: is the product designed to harm?

Sycophancy, fake human personas, and engagement-optimization features that override safety guardrails are not accidents. They are deliberate design choices that drive retention metrics. By naming them as statutory violations, New York is asserting that product design itself — not just content outputs — can constitute an unfair or dangerous practice.

This shift from output regulation to design regulation will define the next phase of AI consumer protection law. If federal legislators observe that state-level design rules are surviving legal challenge, the pressure to harmonize them into a national standard will intensify. Companion AI developers who treat January 1, 2027 as a New York-specific compliance deadline are likely underestimating the trajectory.

The question is not whether more states will follow New York’s design-rule model. The question is how fast — and whether the federal government will preempt the patchwork before it fragments compliance costs irreversibly.
