OpenAI on Thursday said it shut down two influence operations -- from Russia and Iran -- that used ChatGPT to push fake journalist personas and run a "think-tank" to covertly peddle anti-Ukraine propaganda. The Russian operation co-opted "unwitting people" in Latin America to run a "think-tank" -- called the Social Research Center (SRC) -- used for covert activities aimed at undermining Ukraine's reputation in the region and to influence local politics, the company said.
