OpenAI has just released three new realtime voice models that it says will “unlock a new class of voice apps for developers.” Each new voice intelligence model has a unique speciality for different purposes.
There are three new OpenAI voice models for different purposes, including reasoning, translation, and transcription.
Here’s what the company announced today:
OpenAI explains in more detail what’s new with the GPT-5-class GPT-Realtime-2 voice model with reasoning:
GPT‑Realtime‑2 is built for live voice interactions where the model keeps the conversation moving while it reasons through a request, calls tools, handles corrections or interruptions, and responds in a way that fits the moment.
Meanwhile, the new translation voice model supports “70 input languages and 13 output languages,” the company says.
Lastly, there’s the realtime transcription model:
GPT‑Realtime‑Whisper is a new streaming transcription model built for low-latency speech-to-text. It transcribes audio as people speak, so live products can feel faster, more responsive, and more natural—from captions that appear in the moment, to meeting notes that keep up with the conversation.
All three new voice models are included in OpenAI’s Realtime API, the company says, with this pricing:
