AI-generated disinformation represents one of the most immediate near-term risks from AI technology. Generative AI has transformed the economics of disinformation: what once required teams of writers, designers, and media producers can now be accomplished by a single operator with API access. Research by multiple institutions has documented GPT-4-class models producing persuasive political content 5-10x faster than human writers, while image and video generation has made convincing synthetic media widely accessible.

The 2024 global election cycle—with over 40 countries holding major elections—saw the first widespread deployment of AI-generated political disinformation. Documented incidents included AI-generated audio of political figures, synthetic campaign videos, and automated networks producing millions of social media posts. While most instances were identified post-hoc, detection capabilities consistently lagged generation, and some AI-generated content achieved significant spread before identification.

The challenge extends beyond detection to fundamental information ecosystem effects. As AI-generated content becomes indistinguishable from human-created content, the “liar’s dividend” grows: even authentic content can be dismissed as AI-generated. This creates a broader erosion of shared reality that may be more damaging than individual disinformation campaigns.
