## AI 摘要

OpenAI 将语音模型 GPT-Live-1 以 API 形式开放给开发者，支持全双工同时听和说，价格为每分钟 $0.05。相比 GPT-Realtime-2.1，其全双工交互测试得分 80.1% 对 45.4%，轮次延迟从 1.4 秒降至 0.8 秒，工具调用准确率从 60% 升至 87%，银行语音支持基准通过率从 12.4% 升至 32%。

OpenAI is making GPT-Live-1 available to developers as an API. The speech model can listen and talk at the same time, a feature known as "full-duplex," and is already running inside ChatGPT. Developers can pair it with different backend models depending on the task, matching reasoning depth, speed, and cost to each use case. At $0.05 per minute, it's not cheap. Yelp is using the model for phone-based reservations and reports better call handling, according to CTO Alex Levy.

On OpenAI's benchmarks, GPT-Live-1 pulls well ahead of its predecessors. In full-duplex interactivity tests, it scores 80.1 percent compared to 45.4 percent for GPT-Realtime-2.1. Turn-taking latency drops to 0.8 seconds from 1.4 seconds. Tool-calling accuracy jumps to 87 percent from 60 percent. In a banking voice support benchmark, GPT-Live-1 hits a 32 percent pass rate, up from 12.4 percent for the previous model.

GPT-Live-1 also ships with twelve new voices spanning different accents, dialects, and languages. It provides ASR transcripts and response text out of the box. Full details will be available in the API documentation.
