Read Why Seeduplex Wins on Architecture
Every other major voice AI model (GPT-4o Voice, Gemini Live, Claude Voice) operates in half-duplex mode — one party speaks at a time. Seeduplex is the first production full-duplex model, meaning it processes audio input and output simultaneously. This is not a minor improvement — it's a fundamentally different architecture that enables natural interruption, better noise handling, and lower perceived latency.
