OpenAI Releases Three Realtime Voice API Models with GPT-5-Class Reasoning
OpenAI has released three new real-time voice models in its API, graduating the Realtime API from beta to general availability. The models unlock a new class of voice applications covering live reasoning, multilingual translation, and streaming transcription.
The Three New Models
- GPT-Realtime-2: OpenAI's first voice model with GPT-5-class reasoning, capable of handling complex requests, calling multiple tools simultaneously, and managing interruptions while keeping the conversation flowing naturally. Priced at $32 per million audio input tokens and $64 per million output tokens.
- GPT-Realtime-Translate: A live translation model supporting 70+ input languages into 13 output languages, keeping pace with the speaker in real time. Priced at $0.034/minute.
- GPT-Realtime-Whisper: A streaming speech-to-text model that transcribes as the speaker talks. Priced at $0.017/minute.
Realtime API Goes GA
The Realtime API exits beta with this release, making it production-ready for the first time. Developers can now build voice apps that process audio directly in a continuous stream, eliminating latency from separate transcription and synthesis stages. Full details are in the OpenAI blog post.
