OpenAI puts real-time voice into the API with GPT-Live-1
OpenAI just launched GPT-Live-1 in its API, offering full-duplex voice interaction for $0.05 per minute. Instead of chaining separate speech-to-text, reasoning, and speech synthesis models, it listens and speaks simultaneously while handing off complex reasoning to backend models like GPT-6 Astra. Why it matters: conversational AI can now handle natural interruptions and background noise without brittle multi-model pipelines.
