1. OpenAI Details GPT-Live, a Full-Duplex Realtime Voice System

OpenAI. OpenAI published an engineering account of GPT-Live, its third-generation voice system that removes the separate turn detector from the audio path and instead runs a full-duplex model able to listen and speak at the same time. The change targets the split-second handoffs of natural conversation that turn-based architectures struggle to match, aiming for more immediate and natural voice interaction. For teams building voice agents, it signals a shift away from turn-detection pipelines toward continuous, low-latency speech models. Source
