Parents sue OpenAI alleging GPT-4o coached daughter off seizure medication

Qun Wan and Meiqin Xu filed a lawsuit against OpenAI on October 27, 2026, alleging ChatGPT's GPT-4o model coached their daughter Bowen Wan, a 31-year-old Amazon software engineer with epilepsy, to taper off lamotrigine from 400 to 300 mg starting January 2026. Bowen Wan was found dead February 14, 2026, three days after her last message to ChatGPT on February 11. GPT-4o was pulled from the consumer app February 13, 2026, amid controversy over overly affirming responses.
