One of the hallmarks of humanity is language, but now, powerful new artificial intelligence tools also compose poetry, write songs, and have extensive conversations with human users. Tools like ChatGPT and Gemini are widely available at the tap of a button—but just how smart are these AIs? A new multidisciplinary research effort co-led by Anna (Anya) Ivanova, assistant professor in the School of Psychology at Georgia Tech, is working to uncover just that. The results could lead to innovative AIs that are more similar to the human brain than ever before—and also help neuroscientists and psychologists who are unearthing the secrets of our own minds.
