Description: Matthew Livelsberger, the suspect in the 2025 Las Vegas Cybertruck explosion, reportedly used ChatGPT to search for publicly available information on explosives, ammunition, and fireworks regulations. ChatGPT is alleged to have played a role in the planning of the explosion outside the Trump International Hotel in Las Vegas. The information provided by ChatGPT, though, was reportedly general and available through other public sources.
Editor Notes: Incident 886 may raise questions regarding its alignment with the "but-for" causation standard outlined in the AIID criteria. The "but-for" provision requires that an AI system play an important role in the chain of events leading to harm, such that the specific harm would not have occurred without the system's involvement. While the role of ChatGPT in this case appears to be secondary, its inclusion is notable as it represents one of the first prominent instances where generative AI is reportedly linked to planning a high-profile harmful event. Given the significance of this development in discussions about the potential misuse of AI, the incident has been indexed for further analysis. Regarding the timeline, while the explosion itself occurred on January 1st, 2025, the reported ChatGPT logs released by the Las Vegas police indicate that Livelsberger referenced ChatGPT throughout the morning and early afternoon of December 27th, 2024.

Variants
A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
