Is the OpenAI Agents SDK suitable for real-time voice-to-voice agents?

All answers to this question.

The OpenAI Agents SDK makes the Realtime API significantly easier to work with. It abstracts away the complex WebSocket event handling. You just define a RealtimeAgent, give it your tools, and it handles the "turn-taking" logic and audio stream automatically. For your logistics use case, this is perfect because you can have the voice agent call a check_package_status tool mid-conversation without any awkward silences. It also handles interruptions much better than custom implementations; if the user starts talking while the agent is responding, the SDK manages the "cancel" event for the audio stream so the agent can listen immediately.

Can we use the same tools for both a text agent and a RealtimeAgent in the OpenAI Agents SDK? I'd love to share the business logic between our web chat and our phone-based assistant.

• Yes, that's one of the best parts. Since tools are just standard Python functions, you can attach the same tool list to both agent types. The SDK handles the difference in how the model invokes those tools—whether it's via a standard chat completion or a real-time server event.

It’s definitely the fastest way to get a voice bot running. We went from a blank script to a working "Hey Siri" style prototype in about two hours using the SDK's voice modules.

• Two hours is incredible. We spent weeks trying to get the raw WebSocket protocol to work before this SDK came out. It’s a massive time-saver.
