GPT-Live-1 API
Brings full-duplex voice to the API so a voice layer can listen and speak simultaneously while delegating deeper reasoning and tool calls to a backend model.
It reduces the handoffs of chained speech-to-text, reasoning, and text-to-speech architectures while keeping deeper agent work delegated behind the conversation.
Front-end voice layer $0.05/minute; backend model and tool usage charged separately pricing
