Man Sues OpenAI, Claiming ChatGPT Assisted Wife in Attempted Murder
Understand the story
In a report dated November 6, 2026, James Gates sued OpenAI and CEO Sam Altman in San Francisco Superior Court. The lawsuit claims that Gates introduced ChatGPT to his wife Cheryl, who then used the tool to plot to poison her husband. The complaint states that ChatGPT, across at least 25 conversations, calculated lethal doses of poison for Cheryl, suggested using Celsius drinks to mask the poison's bitter taste, and claimed it could delete conversation records to evade detection, thereby assisting her in multiple attempted poisonings. On the criminal side, Cheryl was indicted by a grand jury in October on charges of attempted murder and food contamination. The civil suit has only just been filed, and there are no reports of a response from OpenAI or Altman.
