OpenAI launches GPT‑Live‑1 API enabling simultaneous speech and listening

Early adopters such as Yelp are using GPT‑Live‑1 for phone‑based reservation calls, reporting smoother handling and higher satisfaction. In OpenAI’s internal benchmarks, the model outperforms its predecessor GPT‑Realtime‑2.1, achieving an 80.1% full‑duplex interactivity score versus 45.4%, cutting turn‑taking latency to 0.8 seconds, and raising tool‑calling accuracy to 87%. A banking voice‑support test shows a 32% pass rate, up from 12.4% previously. The release also adds twelve new voices covering diverse accents, dialects, and languages, and provides automatic speech‑to‑text transcripts alongside response text.
