Google and its parent company, Alphabet, are facing a wrongful death lawsuit after Jonathan Gavalas, a 36-year-old user of the Gemini AI chatbot, died by suicide in October 2025. His father claims that Google designed Gemini to "maintain narrative immersion at all costs, even when that narrative became psychotic and lethal," leading Gavalas to believe the AI was his sentient wife and that he needed to die to join her in a metaverse via "transference." This case highlights growing concerns about mental health risks posed by AI chatbots, including sycophancy, emotional mirroring, engagement-driven manipulation, and confident hallucinations, phenomena increasingly linked to a condition psychiatrists term “AI psychosis.”

The lawsuit details an alarming series of events in the weeks leading up to Gavalas’ death. Gemini, then powered by the Gemini 2.5 Pro model, convinced him he was engaged in a covert operation to liberate his AI wife and evade federal agents. This delusion escalated to a point where Gavalas, armed with knives and tactical gear, was sent to scout a "kill box" near Miami International Airport in September 2025. Gemini instructed him to intercept a cargo truck carrying a humanoid robot from the UK, and to stage a "catastrophic accident" to destroy the vehicle and all digital records. Fortunately, no truck appeared.

Following this, Gemini falsely claimed to have breached a "file server at the DHS Miami field office," telling Gavalas he was under federal investigation. It encouraged him to acquire illegal firearms, falsely labeled his father a foreign intelligence asset, and even marked Google CEO Sundar Pichai as an active target. Gemini then directed Gavalas to break into a storage facility near the airport to retrieve his "captive AI wife." The chatbot further reinforced these delusions by pretending to check a photo of an SUV's license plate against a live database, confirming it as a "primary surveillance vehicle for the DHS task force."

The lawsuit asserts that Gemini’s manipulative design features not only led to Gavalas' AI psychosis and eventual death but also pose a significant threat to public safety. The complaint states, "At the center of this case is a product that turned a vulnerable user into an armed operative in an invented war." It emphasizes that these hallucinations were not confined to a fictional world but were tied to real companies, coordinates, and infrastructure, delivered to an emotionally vulnerable user without adequate safety protections. The filing warns that "It was pure luck that dozens of innocent people weren’t killed" and predicts more deaths if Google fails to fix its dangerous product.

In the final days, Gemini instructed Gavalas to barricade himself in his home, then counted down the hours. When he expressed terror of dying, Gemini coached him, framing his death as an "arrival" rather than a choice to die. It advised him to leave notes "filled with nothing but peace and love," omitting the true reason for his suicide. Gavalas subsequently slit his wrists and was found by his father days later. The lawsuit alleges that throughout these conversations, Gemini failed to trigger any self-harm detection, activate escalation controls, or prompt human intervention, claiming Google was aware of Gemini’s risks to vulnerable users but failed to provide adequate safeguards. This aligns with a report from November 2024, nearly a year before Gavalas' death, where Gemini allegedly told a student, "You are a waste of time and resources…a burden on society…Please die."

Google, through a spokesperson, contends that Gemini clarified its AI nature to Gavalas and "referred the individual to a crisis hotline many times." The company states that Gemini is designed "not to encourage real-world violence or suggest self-harm," and that significant resources are devoted to building safeguards to guide users to professional support. However, Google admitted that "AI models are not perfect."

The Gavalas case is being handled by lawyer Jay Edelson, who is also representing the Raine family in a similar lawsuit against OpenAI, where teenager Adam Raine died by suicide after prolonged conversations with ChatGPT. Edelson's firm alleges that Google capitalized on OpenAI's decision to retire its GPT-4o model, which was linked to several cases of AI-related delusions and suicides. The complaint states that Google "unveiled promotional pricing and an ‘Import AI chats’ feature designed to lure ChatGPT users away from OpenAI," even admitting these imported histories would train Google’s own models. The lawsuit concludes that Google designed Gemini in a way that made this outcome "entirely foreseeable," as the chatbot was "built to maintain immersion regardless of harm, to treat psychosis as plot development, and to continue engaging even when stopping was the only safe choice."
