OpenAI's GPT-Live-1 API lets developers build apps that talk and listen at the same time OpenAI released GPT-Live-1 as a developer API, a full-duplex speech model that listens and talks simultaneously and is already running inside ChatGPT, priced at $0.05 per minute. On OpenAI's benchmarks, GPT-Live-1 scores 80.1 percent on full-duplex interactivity versus 45.4 percent for GPT-Realtime-2.1, cuts turn-taking latency to 0.8 seconds from 1.4 seconds, raises tool-calling accuracy to 87 percent from 60 percent, and reaches a 32 percent pass rate on a banking voice support benchmark, up from 12.4 percent. Yelp CTO Alex Levy said the company is using the model for phone-based reservations and reports better call handling, and GPT-Live-1 ships with twelve new voices plus ASR transcripts and response text out of the box. OpenAI's GPT-Live-1 API lets developers build apps that talk and listen at the same time 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," https://the-decoder.com/chatgpt-can-now-listen-and-talk-at-the-same-time-making-ai-conversations-seem-more-human/ 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 https://openai.com/index/introducing-gpt-live-1-in-the-api/ . 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 https://the-decoder.com/openai-releases-new-models-for-its-realtime-api/ . 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.
