GPT-Live is now in beta for every Vapi customer

Vapi has expanded its GPT-Live beta, a full-duplex speech-to-speech model from OpenAI, to all customers after an initial limited testing period with selected teams. Unlike conventional voice-agent pipelines that separately use speech recognition, language models, and text-to-speech, GPT-Live directly processes and produces audio while maintaining continuous listening, enabling more natural pauses, interruptions, backchannel responses, tone recognition, and lower perceived latency. On Vapi, GPT-Live operates through a speaker model that manages the conversation and a separate reasoner model that performs procedures, tool calls, and lookups when prompted to do so. Customers can migrate existing assistants by separating conversational guidance into a speaker prompt and operational procedures into a reasoner prompt, while retaining existing phone numbers, tools, testing, recordings, transcripts, and observability features. Vapi positions speech-to-speech models as an additional option alongside modular voice pipelines, which remain useful for teams needing independent control over transcription, intelligence, and voice components.
