# OpenAI releases GPT-Live-1, a full-duplex voice API

*2026-09-10 · Source: [The Decoder](https://the-decoder.com/openais-gpt-live-1-api-lets-developers-build-apps-that-talk-and-listen-at-the-same-time/)*

OpenAI launched GPT-Live-1, a developer API for building apps that can talk and listen at the same time. The model scores 80.1% on an interactivity benchmark, up from 45.4% for its predecessor, and is priced at $0.05 per minute.

**Why it matters:** Full-duplex, simultaneous talk-and-listen voice has been a persistent weak point for AI assistants, causing awkward turn-taking; a large jump on this metric could make voice agents feel meaningfully more natural. Metered API pricing also signals OpenAI is targeting voice-agent builders directly as a distinct product line.
