GPT-Live 抛弃级联语音管道，采用全双工语音架构
openai 推出了 gpt-live，这是一种全双工语音模型，能够同时听和说以降低延迟并支持自然打断，为新的 chatgpt 语音模式提供动力。
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.
