2/ The secret sauce? Lemon Slice combines a custom diffusion transformer model with Deepgram's voice tech and a slick GPU backend via Modal. They’re stitching it all together so your character looks like it’s actually talking, with smooth emotions and no weird lag.

4/ The team behind it is super tight too—Lina Colucci, Sidney Primas, and Andrew Weitz. They met at Duke, ran a machine learning consultancy together, and helped companies like Nike + Google before starting Lemon Slice. Basically: small team, big energy.

5/ Bottom line: Lemon Slice is making real-time expressive AI avatars feel accessible, fast, and fun. And it’s wild how much they’re pulling off with such a small team. If you wanna see the future of video storytelling, keep an eye on them: lemonslice.com 🍋
