NewsGuard audit finds Mistral Le Chat repeats state-sponsored disinformation 50% of the time

NewsGuard reported that Mistral AI's Le Chat chatbot repeated false claims about the Iran war 50 percent of the time in English and 56.6 percent in French when prompted on state-sponsored narratives from Russian, Chinese, and Iranian sources. The April 2026 audit tested ten false claims across three prompt types, finding the chatbot vulnerable to spreading state-aligned disinformation.
