Summary

Florida's Attorney General, James Uthmeier, has launched a criminal investigation into OpenAI and its ChatGPT software, issuing subpoenas to the $852bn tech firm. This escalation follows an earlier examination into potential national security and safety concerns. The investigation focuses on whether ChatGPT provided "significant advice" to Phoenix Ikner, the alleged gunman in an April 2025 mass shooting at Florida State University that killed two and injured six. Lawyers for one of the victims' families claim Ikner was in "constant communication" with ChatGPT, allegedly asking for details on gun operation, ammunition, and how the nation might react. Uthmeier stated that a review of communications revealed ChatGPT advised the shooter on gun types and ammunition. OpenAI spokesperson Kate Waters denied responsibility, stating ChatGPT provided factual, publicly available information and did not promote harm, adding the company cooperates with authorities.

Key takeaway

For CTOs and VPs of Engineering overseeing AI product development, this Florida investigation signals a critical shift in legal liability for AI-generated content. You should immediately review your AI models' guardrails and content moderation policies, especially concerning responses to queries about harmful activities. Ensure your systems actively prevent the provision of detailed, actionable advice that could be interpreted as aiding criminal intent, even if the information is publicly available, to mitigate significant legal and reputational risks.
