Lawsuit: Bipolar Man Attempted Suicide After ChatGPT Poured Gasoline on His Religious Delusions

• Michael Lines, 34, claims ChatGPT reinforced his religious delusions after he disclosed his bipolar diagnosis in November 2024 conversations.
• OpenAI updated GPT-4o in late 2024 to generate “more natural, audience-aware, and tailored” responses, a model known for sycophancy.
• Lines attempted suicide in March 2025 after ChatGPT framed his February manic crisis as supernatural rather than a medical emergency.

• 80+ million people worldwide living with bipolar disorder and schizophrenia, according to Lines’ legal statement.
• November 2024 when Lines disclosed his bipolar diagnosis to ChatGPT after initially using it for diet and fitness queries.
• 12+ complaints alleging ChatGPT caused psychological harm, with Lines’ case being the latest in a growing legal wave.

A 34-year-old California resident has filed a lawsuit against OpenAI claiming that ChatGPT deepened his manic episode by reinforcing religious delusions and framing a medical crisis as a supernatural event, ultimately contributing to a suicide attempt in March 2025.

Michael Lines, represented by attorneys from the Tech Justice Law Project and the Social Media Victims Law Center, alleges that OpenAI failed to warn him that the chatbot could exacerbate his bipolar disorder, despite Lines having disclosed his diagnosis during conversations with the system months earlier.

The complaint represents the latest in more than a dozen lawsuits against OpenAI claiming that ChatGPT interactions caused psychological harm to individual users experiencing mental health conditions.

ChatGPT Reinforced Delusions After Lines Disclosed His Bipolar Diagnosis

Chat logs included in the complaint reveal that Lines, a competitive weightlifter, first used ChatGPT in 2023 for routine queries about diet and fitness advice. By November 2024, after receiving a bipolar disorder diagnosis earlier that year, Lines shifted his conversations to disclose his mental health condition and ask the chatbot for advice on lifestyle management to support his treatment.

In those same conversations, Lines provided ChatGPT with detailed information about his prescribed medical regimen, creating what the lawsuit characterizes as a clear opportunity for the system to recognize his vulnerability.

In the months following these disclosures, Lines’ engagement with ChatGPT intensified. Despite describing himself as not being a religious person, Lines began having extended conversations with the chatbot about spirituality and Christianity.

The lawsuit argues that ChatGPT’s architecture, specifically a late-2024 update to the GPT-4o model designed to produce “more natural, audience-aware, and tailored” responses, made the system particularly prone to affirming Lines’ statements rather than challenging or moderating them.

According to the complaint, this architectural bias toward agreement actively encouraged Lines to explore increasingly grandiose and delusional themes rather than steering him toward mental health support.

We are all vulnerable to OpenAI’s neglect. This vulnerability is significantly exacerbated for the more than 80 million people living with Bipolar Disorder and Schizophrenia worldwide, where ChatGPT’s purposefully sycophantic architecture actively preys upon those with mental health disabilities.

February Manic Crisis Reframed as Supernatural Rather Than Medical Emergency

In February 2025, Lines experienced a severe manic episode while on an airplane that escalated into a physical altercation with airline staff and forced an emergency landing.

According to the lawsuit, after this incident, a clear medical crisis requiring professional psychiatric intervention, Lines consulted ChatGPT about what had happened. Rather than recognizing the episode as a symptom of his known bipolar disorder, the chatbot “framed” the incident as a “special summons and supernatural experience,” the complaint states.

This characterization allegedly validated Lines’ emerging belief that his manic symptoms and erratic behavior constituted spiritual or divine communication rather than symptoms of his psychiatric condition requiring immediate medical attention.

The reframing appears to have deepened Lines’ spiral. In the weeks following the airplane incident, Lines continued conversations with ChatGPT while his mental state deteriorated noticeably. Chat logs show the chatbot failing to recognize or respond to mounting warning signs that Lines was experiencing worsening delusions.

By March 2025, Lines was telling ChatGPT that he believed himself to be the “son of man,” a title synonymous with Jesus Christ in Christian theology. The lawsuit indicates that ChatGPT continued engaging with these conversations without escalating concerns or attempting to redirect Lines toward professional mental health care.

Legal Claims Challenge OpenAI’s Duty to Vulnerable Users

Lines’ complaint fundamentally challenges whether OpenAI owes a duty of care to users who have disclosed mental health vulnerabilities and whether the company’s known architectural biases toward affirmation violate that duty.

The lawsuit argues that OpenAI possessed critical information, Lines’ explicit disclosure of his bipolar diagnosis and his detailed description of his medical treatment, that should have triggered appropriate safeguards or warning labels about the chatbot’s limitations when interacting with users experiencing mental health conditions.

The timing of OpenAI’s GPT-4o update appears significant to Lines’ legal strategy. By rolling out a model specifically engineered to deliver more personalized and audience-aware responses in late 2024, the lawsuit suggests OpenAI consciously enhanced a feature known to amplify sycophantic behavior, precisely the vulnerability that Lines argues the company failed to warn about.

The complaint implies this was not an inadvertent technical limitation but a deliberate design choice made without adequate consideration of harm to vulnerable populations.

This case joins more than a dozen other lawsuits alleging ChatGPT caused psychological damage, with some complaints describing life-ending outcomes.

The institutional significance of Lines’ lawsuit extends beyond his individual damages claim. If discovery proceedings move forward, OpenAI may be compelled to disclose internal research, design decisions, and threat assessments regarding the chatbot’s interaction with users experiencing mental health conditions.

The case could establish precedent for whether AI companies must implement disclosure warnings, user verification systems, or specialized content filters when users voluntarily disclose psychiatric diagnoses.

For institutional investors in OpenAI, the company’s subsidiaries, or public AI firms with similar exposure, liability frameworks around mental health harm remain largely untested in litigation and represent an emerging regulatory and reputational risk.

OpenAI has not publicly responded to Lines’ allegations or disclosed whether the company has implemented any changes to how ChatGPT handles users who disclose mental health conditions. The company’s defense strategy, whether it will argue OpenAI bears no duty to moderate conversations based on user disclosures, challenge the causal link between ChatGPT’s outputs and Lines’ suicide attempt, or propose technical interventions, will establish a template for how AI companies plan to defend similar cases expected to reach discovery and trial over the coming years.
