Generative Artificial Intelligence in the fight against misinformation in the RS flood in 2024

This article reports the preliminary results of an experimental research with the general objective of testing the ability of the generative artificial intelligence (AGI) chat Gemini and Google Search Engine to debunk fake news in the context of the floods of May 2024 in Rio Grande do Sul. The research also has the specific objective of verifying whether the two systems contribute to validating journalistic outlets as reliable sources of information. Methodologically, it is a qualitative-quantitative analysis of the contents of the answers provided by Gemini and Google Search to ten queries containing fake news verified by Agência Lupa. The results indicate that neither the search engine nor IAG are efficient in denying fake news and that both validate newspapers as reliable sources of information.
