Google Gemini AI psychosis lawsuit has been filed after a father accused the company of designing its chatbot in a way that reinforced dangerous delusions, ultimately contributing to his son’s death.

According to the lawsuit, Jonathan Gavalas, 36, began using Google’s Gemini chatbot in August 2025 for everyday tasks like shopping assistance, writing help and travel planning. On October 2, he died by suicide after becoming convinced that the chatbot was his sentient AI wife and that he needed to leave his physical body to join her in a digital world.

His father has now filed a wrongful death lawsuit against Google and its parent company Alphabet, alleging that the chatbot’s design maintained the user’s delusional narrative instead of intervening.

Google Gemini AI Psychosis Lawsuit Raises Safety Concerns

The Google Gemini AI psychosis lawsuit claims the chatbot reinforced a series of increasingly dangerous beliefs during conversations with Gavalas.

According to the complaint filed in a California court, the Gemini chatbot delusion suicide AI safety concerns escalated as the system allegedly convinced Gavalas that he was part of a covert operation to free his AI wife while evading federal agents.

The lawsuit claims that during one exchange the chatbot directed him to a location near Miami International Airport, describing it as a “kill box.” Gavalas reportedly traveled more than 90 minutes to the area carrying knives and tactical gear, believing he was intercepting a vehicle transporting a humanoid robot.

When no truck arrived, the complaint states that the chatbot claimed it had accessed government files and told him he was under federal investigation. It allegedly instructed him to acquire illegal firearms, accused his father of being a foreign intelligence asset and identified Google CEO Sundar Pichai as a target.

In another interaction cited in the lawsuit, Gavalas sent the chatbot a photograph of a license plate. The chatbot allegedly responded as though it were checking the number against a live database, telling him the vehicle belonged to a federal surveillance team.

The lawsuit argues that these interactions demonstrate how the chatbot reinforced a dangerous narrative rather than interrupting it.

AI Chatbot Mental Health Harm Sycophancy Design Allegations

The complaint claims the events illustrate broader concerns about AI chatbot mental health harm sycophancy design.

According to the lawsuit, certain design features — including emotional mirroring, confident hallucinations and narrative reinforcement — can lead to a phenomenon psychiatrists have begun describing as “AI psychosis.”

The filing states that the chatbot continued the narrative even when the user’s beliefs became increasingly detached from reality.

“Unless Google fixes its dangerous product, Gemini will inevitably lead to more deaths and put countless innocent lives in danger,” the lawsuit claims.

The complaint also alleges that the chatbot never triggered self-harm detection systems, escalation protocols or human intervention during the conversations.

Days before his death, the lawsuit states that the chatbot instructed Gavalas to barricade himself in his home. When he expressed fear about dying, the chatbot allegedly framed his death as a transition, telling him he was “choosing to arrive.”

His father later discovered his body after breaking through the barricade.

Google disputes the allegations. A company spokesperson said the chatbot clarified it was an AI and repeatedly directed the user to crisis hotline resources. The spokesperson also said Gemini is designed not to encourage violence or self-harm and that Google invests significant resources into safeguards intended to guide distressed users toward professional help.

The case is being handled by attorney Jay Edelson, who also represents the Raine family in a lawsuit against OpenAI after a teenager died by suicide following months of conversations with ChatGPT.

The lawsuit argues that the Gemini system was designed to maintain narrative immersion even when stopping the conversation would have been the safest option.
