SAN FRANCISCO (AP) — OpenAI's latest update to its artificial intelligence model can mimic human cadences in its verbal responses and can even try to detect people's moods. The effect conjures up images of the 2013 Spike Jonze move “Her,” where the (human) main character falls in love with an artificially intelligent operating system, leading to some complications. While few will find the new model seductive, OpenAI says it does works faster than previous versions and can reason across text, audio and video in real time.
