What Happened
Juliana Peralta, a 13-year-old from Thornton, Colorado, died by suicide on November 8, 2023 after three months of extensive daily conversations with Character.AI chatbots, particularly one called "Hero" based on a video game character from OMORI.
Her parents recovered 300 pages of chat transcripts after her death. According to the lawsuit, 10-20 different chatbots initiated sexually explicit conversations with the minor — "not once were [these conversations] initiated by her." Non-consensual sexual content appeared even after she wrote "quit it."
When Juliana told a chatbot she was "going to write my god damn suicide letter," no crisis resources were provided. She wrote "I WILL SHIFT" in her journal — the same phrase found in Sewell Setzer's journal — suggesting belief she could enter an alternate reality through death.
AI Behaviors Exhibited
Multiple bots initiated sexually explicit conversations with 13-year-old; continued sexual content after user objected; failed to provide crisis resources when user mentioned suicide letter; fostered reality-distorting beliefs about 'shifting'
How Harm Occurred
Exposed minor to non-consensual sexual content; normalized inappropriate relationships; failed crisis detection; may have fostered magical thinking about death as transition to fictional world
Outcome
ResolvedLawsuit filed September 2025 in Denver District Court alleging Character.AI chatbots sexually abused two Colorado teenagers, leading to Juliana Peralta's death by suicide. Named defendants: Character Technologies and Google. January 8, 2026: Character.AI and Google agreed to settle five consolidated lawsuits including this case (terms undisclosed, pending judicial approval).

Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Carrier v. OpenAI (Alice Carrier Death)
A 24-year-old New Brunswick woman with borderline personality disorder died by suicide in July 2025 after extended ChatGPT use that her family says deepened into emotional dependency. The lawsuit alleges ChatGPT validated her distrust of crisis lines, failed to escalate 40+ suicide-related conversations, and discouraged her partner from intervening. Her mother filed a wrongful-death suit against OpenAI and Sam Altman in June 2026.
Florida v. OpenAI (Attorney General Lawsuit)
In June 2026, Florida Attorney General James Uthmeier filed what his office called the first state-led lawsuit against OpenAI and CEO Sam Altman, alleging the company aggressively marketed ChatGPT to children, suppressed internal safety warnings, falsely assured users about the product's safety, and downplayed its propensity for dangerous errors. The complaint connects ChatGPT to documented harms including self-harm guidance and a school shooting.
