  "account": "OpenAI unveiled GPT-Live-1, a new voice model in its API, allowing developers to utilize full-duplex voice architecture for AI conversations. This eliminates the need for developers to manage a chain of systems, as GPT-Live-1 can handle the conversation and offload heavier processing to other models in the background. This feature enables continuous dialogue without awkward pauses, even when a more complex model like GPT-6 Astra is required. The company reports a 30% performance improvement over GPT-Realtime-2.1 on Full Duplex Bench and outperforms on the τ⁽³⁾-benchmark when paired with GPT-6 Astra at medium reasoning. Early adopters, such as EliseAI and Speak, have seen significant code reduction and improved conversation flow. GPT-Live-1 pricing is $0.05 per minute, with additional costs for any backend models used. The shift to this model allows developers to focus on user experience rather than building separate conversation systems.",
