Ello built a real-time AI tutor that responds to 5-year-olds in under 1 second

Catalin Voss's team at Ello solved the latency problem that makes most AI tutors feel sluggish and unresponsive for young learners. By optimizing inference to stay under 1000ms, they created something that actually feels conversational rather than robotic—a constraint that matters more for early childhood education than most people building AI products realize.
