Restaurant reservations don’t always follow a script.

OpenAIDevs highlighted Yelp using OpenAI's GPT-Live-1 to make restaurant reservation calls, framing the model's relevant capability as listening while it speaks, which lets a caller interrupt, add details, or change direction mid-conversation rather than waiting for a scripted turn to end. GPT-Live-1 launched in the API two days earlier as a model built to handle real-time voice interaction end to end, delegating reasoning and tool calls to a separate backend model so the conversational layer stays responsive.
