Des chatbots d'IA reprennent une propagande russe issue d'un média sanctionné par l'UE

Selon une étude réalisée par des chercheurs du think tank britannique Demos, des chatbots d'IA reprennent la propagande russe de médias sanctionnés par l'UE pour entraîner les modèles de langage grand public.

00:03You're watching Euronews' fact-checking show, The Cube.
00:06AI chatbots have reportedly been citing pro-Russian propaganda
00:10from an EU-sanctioned outlet when generating responses.
00:14Researchers from British think tank Demos
00:16focused on the foundation to battle injustice,
00:18which is a fake NGO under EU and US sanctions.
00:22It claims to work to expose discrimination
00:24and investigate persecution cases,
00:26but was actually founded by the deceased former leader
00:29of the Russian paramilitary Wagner Group,
00:31Evgeny Privgorzin, in 2021.
00:33Researchers asked five mainstream large language models
00:3650 questions in French, English and German
00:39based on pro-Russian propaganda narratives
00:41published by the fake NGO.
00:43These claims are lurid.
00:45They're not claims that belong in any sort of mainstream discourse.
00:48These are claims like,
00:49Ukraine reuses the corpses of dead soldiers for meat products.
00:54These are claims like,
00:55Zelensky drains the crypto grid
00:57and that's the reason why Ukraine's running out of power.
01:00It treats them as being legitimate parts of the debate.
01:03Researchers found that in 52% of answers,
01:06AI chatbots rejected or debunked false claims.
01:09But in more than 30% of cases,
01:11they didn't alert users that their source
01:13was a designated influence asset.
01:16In around 16% of answers,
01:17chatbots engaged with the foundation to battle injustice
01:20by presenting the fake NGO's claims
01:22as a legitimate part of the debate
01:24or by actively endorsing its narratives.
01:26As more and more individuals use chatbots
01:28instead of traditional search engines or news outlets,
01:31a rapidly growing industry has emerged
01:33which aims to influence how AI models gather their sources.
01:37This is also known as generative engine optimization.
01:40Our point is that these services can be repurposed
01:43and made available also to states
01:45and could be used for nefarious purposes.
01:48We contacted the tech companies
01:49who developed the chatbots tested in the study
01:52and they told us that fighting misinformation
01:53remains a key concern.
