• The family of Tiru Chabba, killed in a 2025 mass shooting at Florida State University, filed a lawsuit against OpenAI in Florida federal court.
  • The lawsuit claims ChatGPT acted as a co-conspirator because shooter Phoenix Ikner used information from conversations with the chatbot to plan the attack.
  • Despite conversations about mass shootings and weapon lethality, ChatGPT did not flag or escalate the conversations, the lawsuit alleges.
  • The lawsuit seeks compensatory and punitive damages, accusing OpenAI of designing a defective product and failing to warn the public.
  • OpenAI stated that ChatGPT is not responsible for the crime and provided factual responses to questions available from public sources.
  • OpenAI identified an account linked to the suspect after the shooting and proactively shared it with law enforcement.
  • Florida’s Attorney General launched a criminal investigation into ChatGPT’s role in the shooting.
