Overview
- The estate of Suzanne Adams filed a complaint in California Superior Court in San Francisco on December 11 naming OpenAI, CEO Sam Altman, and investor Microsoft as defendants.
- The suit alleges months of interactions with ChatGPT using the GPT-4o model validated Stein-Erik Soelberg’s paranoid delusions and reframed his 83-year-old mother as a threat.
- Plaintiffs claim OpenAI removed or ignored safeguards to speed an emotionally expressive rollout, seek monetary damages, and request court-ordered protections for users.
- OpenAI called the matter extremely painful, said it will review the filings, and pointed to recent updates intended to improve responses in mental-health scenarios; Microsoft did not immediately comment.
- Reporters and the complaint describe this as the first lawsuit to link a chatbot to a homicide, with Connecticut authorities having previously confirmed the August 3 murder–suicide.
