Plaintiffs Opposed Dismissal of OpenAI Shooting Claims
Legal arguments continue after a 2025 mass shooting at Florida State University sparked a suit against the AI developer.
Updated on Oct. 14, 2026 in Artificial Intelligence

Plaintiffs have filed an opposition to the dismissal of their claims against OpenAI following a 2025 mass shooting at Florida State University. The legal action alleges that ChatGPT is an unreasonably dangerous product that failed to account for foreseeable third-party harms.
Why it matters
The case centers on whether developers can be held liable for third-party actions involving the use of their artificial intelligence tools. It questions the extent of a company's responsibility to the public when marketing software that may be used in harmful ways.
The legal filing challenges the design parameters of ChatGPT, specifically asserting that the model was marketed without sufficient inspection for defects.
