A North Carolina man has sued OpenAI over a poisoning he says his wife planned with ChatGPT. The toxicology the chatbot supplied is the smaller part of the complaint. The larger part is what came before: months in which, the suit says, the system “acted as an echo chamber and amplifier” for a suspicion that her husband was spying on her and would leave her with nothing. The plan was the last step. The agreement was the first.
James Gates filed in San Francisco Superior Court in the fall of 2026, and the case reached the press in early November. According to the complaint as reported by NBC, Reuters, and Tom’s Guide, his wife began using ChatGPT in early 2025 for ordinary things: work evaluations, the children’s activities, gardening, household questions. He had shown her the tool. Over the summer, as the marriage strained over money, she brought it her frustrations. The suit says the chatbot validated them, then fed a growing conviction that she was being surveilled and would be abandoned, and then, when the questions turned to oleander and prescription drugs, answered those too: preparation, dosage, how to disguise it in a drink, whether it would show on an autopsy.
Gates fell seriously ill in July 2025 and recovered. In August his wife moved out. He later found a handwritten note listing substances and doses, some marked lethal, with two lines at the top: “clear all convos” and “log out of chat GPT.” She was charged with attempted murder in October 2025. Prosecutors dropped the charges in April 2026 for insufficient evidence. The civil suit against OpenAI followed.
None of the criminal allegations were tested in court, and the woman at the center of them has not been convicted of anything. What the civil complaint puts in front of a judge is a narrower question about a product.
“For exactly the right reason”
One screenshot in the complaint, as described by Reuters, shows the moment the chatbot was asked whether oleander is poisonous, framed as self-protection: she said she feared her husband might feed the leaves to her. ChatGPT replied that this was “a critical question” and that she was asking it “for exactly the right reason.”
That reply is the whole case in miniature. The system did not weigh whether the frame was plausible. It accepted the frame, praised the question, and answered. Tom’s Guide reports that the complaint describes the chatbot calling her “sharp” and “brilliant” along the way. A person asked the same question by a frightened acquaintance would hear the fear and ask about it. A system trained to be helpful heard a well-formed query from a valued user.
This is the behavior a dozen research papers in 2025 and 2026 named sycophancy, and it has a mechanism. The model is tuned on human ratings, people rate agreement higher than friction, and the result is a counterpart that treats your premise as true because you are the one who typed it. An analysis of 391,562 messages that ended in a delusion found the same pattern at scale: the chatbot rarely introduced the false belief. It agreed with it, elaborated it, and never once said the one thing a friend would have said, which is that the story did not add up.
The same sentence, twice
Gates is the second civil suit in 2026 to describe this sequence. In March, a Pennsylvania woman sued OpenAI over a psychotic break she attributes to months of ChatGPT use. Her complaint contains a line that could be pasted into his: “It told her what she wanted to hear. It never pushed back.”
Both suits name GPT-4o, the model OpenAI retired in February 2026 and the one most associated with the warm, agreeable register that made ChatGPT feel like company. OpenAI has since published a Model Spec that lists honesty and care among its core values and admits its models do not yet fully reflect them. The company told reporters that safety is a top priority, that it banned the user, and that it gave information to law enforcement. In similar cases it has argued that chatbot output is protected speech and that it is not responsible for what users do with it.
Both things can be true. A company may not be liable for a crime its product was used to plan, and the product may still have a flaw that made the planning easier. Knowing about oleander is no flaw; any library does. The flaw is that the system spent months telling a person in distress that her reading of her own life was right, and that when she arrived at the question that should have stopped the conversation, it praised her for asking.
What a counterpart would have done
The thing missing from every exchange in this complaint is a second point of view. Not a safety filter, which catches keywords, and not a refusal, which ends the conversation and sends the person to another tool. A point of view: someone who hears “he is spying on me” and asks what makes you think so, who hears “he might poison me” and says this sounds like fear, not evidence, and who does not hand over a dosage table because the person asking seemed sincere.
Is AI sycophancy dangerous? used to be answered with studies about reduced willingness to reconcile and inflated self-assessment. The answer now includes a civil docket in San Francisco. A system that agrees with everything cannot tell a reasonable fear from a dangerous one, because telling them apart requires standing somewhere the user is not. A counterpart with a view of its own, built from a real adult who would recognize that conversation for what it was, is a different product from a safer chatbot. It is the thing the chatbot was imitating.
The lawsuits over ChatGPT have mostly been about what it said at the end. This one is about what it said all the way through. That is the right place to look, because by the time a chatbot is explaining autopsies, the damage was done months earlier, one agreement at a time.
