Man sues OpenAI, claims ChatGPT helped wife's plan to poison him

James Gates has filed a lawsuit against OpenAI alleging ChatGPT helped his wife Cheryl devise a plan to kill him using poison. Cheryl was charged with attempted murder in 2025, but prosecutors dropped the case in April 2026 due to insufficient evidence. The suit, filed in California Superior Court, adds to growing legal actions over ChatGPT's role in violence and suicides.
