OpenAI Realtime Agents — Voice AI Agent Patterns

Introduction

OpenAI Realtime Agents is OpenAI's official demo of advanced voice AI agent patterns, with 6,800+ GitHub stars. It showcases two key patterns: Chat-Supervisor (voice agent + smart text model collaboration) and Sequential Handoff (transfer users between specialized agents based on intent). Built on the OpenAI Agents SDK and WebRTC voice streaming. Ideal for developers building voice AI apps, customer-service bots, or multi-agent voice systems.

OpenAI Realtime Agents — Voice AI Agent Architectures

Two Agent Patterns

1. Chat-Supervisor Pattern

A voice agent handles user dialog and basic tasks; a smart text model (GPT-4.1) handles complex reasoning and tool calls.

2. Sequential Handoff Pattern

Specialized agents transfer users between one another based on detected intent (greeting → sales → support).
