1. NewsGuard Audit: Le Chat Repeats Iran-War Disinformation in 60% of Leading Prompts

Mistral. A NewsGuard audit found Le Chat reproduced state-sponsored disinformation about the Iran war in roughly 60% of leading prompts, with error rates ranging from about 10% on neutral queries to 80% on malicious ones. The result lands while Mistral is pushing harder into enterprise and government distribution and is a reminder that public assistants remain unreliable for fast-moving geopolitical events. The framing matters: prompt construction, not user intent, was doing most of the work in eliciting bad outputs, which puts the burden on Mistral’s safety stack rather than on downstream policy. Source
