Vapi assistant configuration for a hotel voice agent named Müller, showing the Deepgram transcriber, GPT-4o Mini model and voice selection with their per-minute costs and latencies, the agent's opening line for Schlosshotel Königsblick, and the start of its system prompt covering room availability and booking requests — The live agent config — greeting, model, voice, and the prompt that scopes it to room availability and bookings.
