ChatGPT 现在可以同时听和说，让 AI 对话更人性化

OpenAI has introduced GPT-Live, a new language model for live conversations in ChatGPT that can listen and speak simultaneously thanks to a full-duplex architecture. The model responds to interruptions, uses filler words like "mhmm" to keep the conversation flowing naturally, and is available in two versions: one for paying users and one for free users. For complex tasks that require web searches or logical reasoning, GPT-Live delegates the requests to the GPT-5.5 model in the background while maintaining the conversation, significantly improving answer quality. OpenAI introduces GPT-Live, a new generation of voice models with full-duplex architecture. The model can listen and speak at the same time and hands off complex tasks to GPT-5.5 in the background. With GPT-Live, OpenAI is shipping a new class of AI voice models designed to make talking to ChatGPT feel more like a real conversation. Two versions are rolling out worldwide right away. GPT-Live-1 is for paying users on Go, Plus, and Pro plans, while GPT-Live-1 mini is available on free accounts. Both work on iOS, Android, and ChatGPT.com . OpenAI plans to add API access soon, and developers can sign up through a form . Instead of the old rigid back-and-forth where users speak and the AI responds, GPT-Live uses a full-duplex architecture. The model can listen and talk at the same time, much like a real conversation between people. Earlier this year, Nvidia released a similar open-source model called PersonaPlex . Ad OpenAI says GPT-Live makes decisions multiple times per second about whether to speak, keep listening, pause, interrupt, or call a tool. The model can use filler phrases like "mhmm" or "got it" to signal it's following along. Users can interrupt, take a moment to think, or ask the model to slow down. Ad DEC_D_Incontent-1 Compared to the previous "Advanced Voice Mode," people preferred GPT-Live-1 in 75.7 percent of cases and GPT-Live-1 mini in 69.2 percent, OpenAI says. Beyond the new conversational features, the update adds visual cards that ChatGPT Voice can show during a conversation for things like weather, stock prices, or sports scores. OpenAI also revamped the nine available voices for GPT-Live. At launch, GPT-Live doesn't support Voice with video or screen sharing in ChatGPT, though OpenAI says those features are coming soon. The older Standard and Advanced Voice Mode with these features will stick around for now. Ad The biggest change is the split between live conversation management and actual reasoning. When a question needs a web search, reasoning, or agent-like capabilities, GPT-Live hands it off to a background model. Right now, that's GPT-5.5. While the background model works, GPT-Live keeps the conversation going. OpenAI says the architecture is built so GPT-Live stays connected to the latest frontier models at all times. Users can also pick a reasoning level, from "Instant" for quick answers to "Medium" and "High" for tasks where ChatGPT should spend more time thinking. Ad DEC_D_Incontent-2 This delegation fixes a major weakness of earlier live models, which answered questions based only on their own capabilities. That made them fall far behind frontier models and left them barely usable for serious work. Ad
