OpenAI Brings GPT-5-Class Reasoning to Real-Time Voice With Three New API Models

Overview

OpenAI has expanded its Realtime API with three new voice models that bring advanced reasoning capabilities to real-time audio applications. This update marks a significant step toward making GPT-5-class intelligence accessible in low-latency voice interfaces.

What Changed

Three new Realtime API voice models with reasoning support

Combines low-latency audio processing with advanced chain-of-thought reasoning

Fully compatible with existing Realtime API integrations

Developer Impact

Developers building voice agents, customer support bots, and real-time translation tools can now access reasoning-grade intelligence without sacrificing response speed. Previously, achieving both reasoning depth and real-time voice was a significant engineering challenge requiring separate model calls and complex orchestration.
