I'm a bit suspicious of this report - they don't reveal nearly enough about their methodology for me to evaluate how credible this is. When it says "The 10 leading AI tools repeated false information on topics in the news more than one third of the time — 35 percent — in August 2025, up from 18 percent in August 2024" - 35% of what ?

>35% of what? Well it says 35% of the time so I would guess that they’re talking about the number of incidents in a given time frame. For example if you asked me what color the sky is ten times and I said “carrot” four times, you could say that my answer is “carrot” 40% of the time
There is an enormous difference between "35% of times a user asks a question about news" and "35% of the time against our deliberately hand-picked collection of test questions that we have not published".
