GPT-Live 抛棄級聯語音管道，採用全雙工語音架構
openai 推出了 gpt-live，這是一種全雙工語音模型，能夠同時聽和說以降低延遲並支援自然打斷，為新的 chatgpt 語音模式提供動力。
openai introduced gpt-live, a new voice model family built on a full-duplex architecture that listens and speaks simultaneously, ending the trade-offs of cascaded systems that chained stt, llm, and tts models. gpt-live can handle interruptions, back-channeling like 'mhmm', and delegate complex reasoning to gpt-5.5 in the background without halting the conversation flow. the rollout includes gpt-live-1 and gpt-live-1 mini for chatgpt voice, with api access coming later. this shift moves ai interaction toward fluid, human-like conversation suitable for complex, long-running agentic workflows.
