OpenAI has launched GPT‑Live‑1 in its API, priced at $0.05 per minute for front‑end voice interactions, letting developers pair it with backend models and agent harnesses.
OpenAI has opened access to its new full‑duplex voice model, GPT‑Live‑1, via the public API as of 10 September 2026. Developers can now call the front‑end voice layer at a flat rate of $0.05 per minute, billed by the second, and combine it with any backend model or agent framework that fits their product. The pricing model targets the “front‑end voice layer” rather than the underlying language processing, allowing firms to build voice‑first experiences that scale with usage without the need for bespoke infrastructure.
The move matters because voice interfaces have long been hampered by high latency and unpredictable costs. By offering a dedicated, low‑cost voice endpoint, OpenAI lowers the barrier for startups and enterprises to embed real‑time conversational speech into apps, from virtual assistants to customer‑service bots. The flat‑rate structure also simplifies budgeting, a contrast to earlier per‑token or per‑second schemes that could balloon in high‑traffic scenarios.
What to watch next includes how quickly developers adopt the model and whether the pricing holds as demand grows. OpenAI may expand the offering with higher‑quality or multilingual variants, or adjust rates in response to competitive pressure from other AI providers. Observers will also monitor integration patterns—whether the “one API key for all models” approach encourages broader multi‑modal applications, and how the voice capability influences the broader AI market in the Nordics and beyond.
