OpenAI has released GPT-Live-1 as a developer API, bringing full-duplex conversational audio to third-party applications. The model processes incoming user speech while simultaneously streaming voice output, scoring 80.1 percent on interactivity benchmarks compared to 45.4 percent achieved by its predecessor. Priced at $0.05 per minute, the API addresses the friction of rigid turn-taking in voice agents, while establishing a clear commercial rate for continuous conversational audio.
