Advancing voice intelligence with new models in the API

We’re introducing three audio models in the API that unlock a new class of voice apps for developers.

核心内容

With these models, developers can build voice experiences that feel more natural, respond more intelligently, and take action in real time: - GPT‑Realtime‑2, our first voice model with GPT‑5‑class reasoning that can handle harder requests and carry the conversation forward naturally.

- GPT‑Realtime‑Translate, a new live translation model that translates speech from 70+ input languages into 13 output languages while keeping pace with the speaker.

- GPT‑Realtime‑Whisper, a new streaming speech-to-text that transcribes speech live as the speaker talks.

Try GPT-Realtime-2 What can I ask?

After you start the session, try saying one of these: - I’m hosting a last-minute dinner tonight.

I have 30 minutes, two vegetarian friends, one mushroom-hater, and a tiny kitchen.

Help me plan a simple menu.

- I’m welcoming guests to a live event in Japan.

Say a warm, natural welcome in Japanese — like a host kicking off something special.

- My order number is Orbit-742Q.

Repeat it back clearly so I can confirm it’s right.

- Help me practice telling my team we hit our launch milestone.

First say it with quiet confidence, then with more excitement.

- I’m planning trivia for a road trip.

Give me three trick questions that sound deceivingly simple, then explain each answer in one sentence.
