Most of the EU is busy regulating and designing plastic bottle caps πŸ₯± Meanwhile this is our new emotion model for AI avatars. Can you even tell this isn’t a real video any longer?

These AI avatars are arguably the best in the world. Which do you think is actually me: A or B? Please answer the poll below. I’m curious what percentage are fooled! Was in NYC to interview @synthesiaIO CEO/cofounder @vriparbelli and had fun making this avatar. β€” πŸ‘‹ Hi, I’m Harper, AI educator, engineer and advisor. I have two degrees in Computer Science specializing in Artificial Intelligence from Stanford, experience teaching PhD-level AI courses there, and 4 years building AI at Facebook / Meta

GPT-4o voice mode is really impressive. We gave it a face with @synthesiaIO EXPRESS-1, our latest avatar model. When empathy is important – healthcare, coaching, education - a friendly face really makes a difference. It's why we do Zoom over phone calls. What do you think?
