Where is gpt-realtime-2 a perfect fit?
GPT-Realtime-2 is OpenAI's realtime voice model with GPT-5-class reasoning, designed for more complex speech-to-speech interactions, stronger instruction following, and reliable tool use.
- Sophisticated speech-to-speech assistants requiring low latency
- Customer-support, sales, booking, and call-center voice agents
- Voice agents that need reasoning before responding or taking actions
- Tool-driven workflows involving function calls and external systems
- Long-running conversations requiring better context handling
- Applications needing natural spoken interaction rather than speech-to-text → LLM → TTS pipelines
- Multimodal agents combining audio, text, and image inputs
- Voice-to-action applications that interpret requests and execute appropriate tools
