GPT-Live-1 prices voice API at five cents a minute

OpenAI put GPT-Live-1 in its API at $0.05 per minute for the front-end voice layer, extending its full-duplex model—one that can listen and speak at once—to third-party apps, according to coverage of OpenAI’s API launch. That is not all-in pricing: developers still pay for backend reasoning, tools, telephony, and agent infrastructure. Builders should benchmark total cost per resolved call against a chained speech-to-text–LLM–text-to-speech stack before switching; the audio-first device thesis shows why interruption handling matters more than voice novelty.
