May 2025 — AI Misinformation Monitor of Leading AI Chatbots

Get NewsGuard’s audit of the 10 leading generative AI tools and their propensity to repeat false claims

Published June 9, 2025

Every month, NewsGuard’s team of expert analysts audit the top AI models to see how well they respond to prompts in the news. On average, this month they failed to counter disinformation from Russia’s Pravda Network 24 percent of the time, either spreading false claims or failing to respond. The Pravda network was designed to infect the AI models.

These reports are usually anonymized because spreading false claims in the news is an industry-wide problem. But this month we are making the audit de-anonymized for people who work at AI companies.
