g1: Photo of Renan Santos making an “L” for Lula is fake and AI-generated

Fato ou Fake, from g1, verified that a photo of Renan Santos making an “L” gesture in support of Lula is fake and was created with artificial intelligence. OpenAI’s detector identified synthetic content and detected the SynthID watermark; Renan’s press office confirmed that it was a fabrication and said he will not support either candidate in the runoff.

Renan Santos came fourth in the presidential race in the first round, with 2.24% of the votes. According to g1, he had said that his voters would be free to choose whom to support in the runoff.

Why it matters · editorial interpretation

The case underscores how AI-generated political content can attribute a position to a candidate that, according to his press office, he did not take. Identification by OpenAI’s detector and SynthID, together with g1’s fact-checking, reinforces the importance of verifying images before treating them as endorsements.
