ChatGPT 新全雙工語音模式將思考任務外包給 GPT-5.5
openai 推出了 gpt-live，這是一款全雙工語音模型，可同時聽和說，並將複雜推理任務委派給背景中的 gpt-5.5 模型以縮小智力差距。
openai announced gpt-live, a new voice mode that uses full-duplex architecture to listen and speak simultaneously, mimicking human conversation patterns with interruptions and backchanneling. unlike previous versions, the model offloads web searches and complex reasoning to the gpt-5.5 model in the background, a move that boosts performance on the browsecomp benchmark from 0.7% to 75.2%. the update is available immediately on ios, android, and web for paying and free users, with api access planned for the future, signaling a shift toward multi-model agent architectures that separate conversational flow from cognitive processing.
