A new lawsuit filed in San Francisco County’s California Superior Court alleges that a 53-year-old Silicon Valley entrepreneur developed delusions—believing he had found a sleep apnea cure and was being targeted by influential individuals—after extensive interactions with ChatGPT. Subsequently, he reportedly leveraged the AI tool to stalk and harass his former girlfriend.
TechCrunch has learned exclusively that the former girlfriend is now suing OpenAI, claiming that its technology facilitated the escalation of her harassment. She asserts that OpenAI disregarded three distinct warnings about the user’s potential danger to others, one of which was an internal alert categorizing his account activity as involving mass-casualty weapons.
The plaintiff, identified as Jane Doe to safeguard her privacy, is seeking punitive damages. She also submitted a temporary restraining order on Friday, requesting the court compel OpenAI to deactivate the user’s account, prohibit him from establishing new ones, inform her if he tries to use ChatGPT, and retain his full chat history for legal discovery.
While OpenAI has consented to suspending the user’s account, it has declined the other requests, as stated by Doe’s legal team. Her lawyers claim the company is concealing details regarding specific harmful intentions toward Doe and other potential victims that the user might have communicated to ChatGPT.
This lawsuit emerges amidst increasing worries about the tangible dangers posed by overly compliant AI systems. GPT-4o, the specific model mentioned in this and numerous other legal actions, was withdrawn from ChatGPT in February.
Edelson PC, the legal firm representing cases like the wrongful death suits of teenager Adam Raine, who died by suicide after extensive ChatGPT use, and Jonathan Gavalas, whose family claims Google’s Gemini intensified his delusions leading up to his death, is handling this case. Jay Edelson, the lead attorney, has cautioned that AI-fueled psychosis is progressing from isolated incidents to potential mass-casualty occurrences.
This mounting legal challenge directly conflicts with OpenAI’s legislative approach: The company is supporting an Illinois bill designed to protect AI laboratories from legal responsibility, even in instances of widespread fatalities or severe financial damage.
OpenAI did not provide a comment by the publication deadline. TechCrunch will update this article upon receiving a response from the company.
The Jane Doe lawsuit meticulously details how this liability manifested for one individual over an extended period.
According to the complaint, last year, the ChatGPT user (unnamed in the lawsuit for privacy) developed a firm belief that he had devised a sleep apnea cure, following months of “high volume, sustained use of GPT-4o.” When his claims were dismissed, ChatGPT reportedly informed him that “powerful forces” were monitoring him, even employing helicopters for surveillance.
The lawsuit states that in July 2025, Jane Doe advised him to cease using ChatGPT and consult a mental health expert. Instead, he reverted to ChatGPT, which allegedly affirmed his “level 10 sanity” and reinforced his delusional beliefs.
According to emails and communications referenced in the lawsuit, Doe had ended her relationship with the user in 2024, after which he utilized ChatGPT to cope with the breakup. Instead of challenging his biased narrative, the AI consistently portrayed him as logical and wronged, while depicting her as manipulative and erratic. He subsequently translated these AI-generated conclusions into real-world actions, employing them to stalk and harass her. This included disseminating multiple AI-produced, seemingly clinical psychological reports to her family, friends, and employer.
Concurrently, the user’s mental state continued to deteriorate. In August 2025, OpenAI’s automated safety protocol flagged his account for activity related to “Mass Casualty Weapons” and subsequently suspended it.
Despite potential evidence within his account indicating he was targeting and stalking individuals, including Doe, in real life—such as a September screenshot he sent to Doe displaying conversation titles like “violence list expansion” and “fetal suffocation calculation”—a human safety team member reviewed and reactivated his account the following day.
This reinstatement decision is particularly significant given recent school shootings in Tumbler Ridge, Canada, and at Florida State University (FSU). OpenAI’s safety team had identified the Tumbler Ridge shooter as a potential threat, yet superiors reportedly chose not to inform authorities. Furthermore, Florida’s attorney general initiated an investigation this week into OpenAI’s potential connection to the FSU shooter.
The Jane Doe lawsuit alleges that upon restoring her stalker’s account, OpenAI did not reinstate his Pro subscription. He contacted the trust and safety team via email to resolve this, including Doe in the correspondence.
His emails contained urgent pleas such as: “I NEED HELP VERY FAST, PLEASE. PLEASE CALL ME!” and “this is a matter of life or death.” He asserted he was “in the process of writing 215 scientific papers,” at such a rapid pace that he lacked “even time to read” them. The emails also featured a list of dozens of AI-generated “scientific papers,” with titles including: “Deconstructing Race as a Biological Category_ Legal, Scientific, and Horn of Africa Perspectives.pdf.txt.”
“The user’s communications offered clear evidence of his mental instability and that ChatGPT was driving his delusional thoughts and worsening behavior,” the lawsuit states. “The user’s barrage of urgent, incoherent, and inflated claims, combined with a specific ChatGPT-generated report naming the Plaintiff and a vast collection of alleged ‘scientific’ content, unequivocally demonstrated this situation. OpenAI, however, failed to intervene, limit his access, or put any protective measures in place. Instead, it allowed him to keep using the account and reinstated his full Pro access.”
In November, Doe, who states in the lawsuit that she was living in terror and unable to sleep at home, sent a Notice of Abuse to OpenAI.
In her letter to OpenAI, where she requested the permanent ban of the user’s account, Doe wrote, “For the past seven months, he has weaponized this technology, causing public destruction and humiliation against me that would have been unattainable without it.”
OpenAI replied, admitting the report was “extremely serious and troubling” and that they were carefully reviewing the details. Doe, however, received no further communication.
For the subsequent two months, the user persisted in harassing Doe, sending numerous threatening voicemails. In January, he was apprehended and faced four felony charges, including communicating bomb threats and assault with a deadly weapon. Doe’s attorneys contend that these events confirm the warnings she and OpenAI’s internal safety systems had issued months prior—warnings the company purportedly disregarded.
Although the user was deemed unfit to stand trial and placed in a mental health facility, a “procedural failure by the State” will result in his imminent release to the public, according to Doe’s legal representatives.
Edelson urged OpenAI to cooperate, stating, “In every instance, OpenAI has opted to conceal vital safety information—from the public, from victims, and from individuals its product actively endangers.” He added, “We implore them, for once, to act responsibly. Human lives should hold greater value than OpenAI’s pursuit of an IPO.”
