OpenAI Ships GPT-Realtime-2, Live Translate, and Realtime Whisper in the API
On May 7, 2026, OpenAI released a new generation of Realtime API voice models: GPT-Realtime-2 with GPT-5-class reasoning for live voice agents, GPT-Realtime-Translate for speech translation across 70+ input languages into 13 outputs, and GPT-Realtime-Whisper for streaming speech-to-text—all aimed at production voice apps rather than ChatGPT Voice alone.
TLDR
OpenAI on May 7, 2026 announced three new Realtime API voice models for developers: GPT‑Realtime‑2 (most intelligent speech-to-speech path yet, with GPT‑5-class reasoning for harder multi-turn voice agents), GPT‑Realtime‑Translate (live speech translation: 70+ input languages → 13 output languages), and GPT‑Realtime‑Whisper (streaming speech-to-text while the user is speaking). All ship in the Realtime API (Playground available); pricing includes $32/$64 per million audio input/output tokens for Realtime‑2 (with $0.40 cached input) and per-minute rates for Translate ($0.034/min) and Whisper ($0.017/min).
What shipped
From OpenAI’s primary post “Advancing voice intelligence with new models in the API” and TechCrunch/community notes:
| Model | Role | Notes |
|---|---|---|
| GPT‑Realtime‑2 | Live conversational voice agents | Successor-class to Realtime‑1.5; better context and complex requests |
| GPT‑Realtime‑Translate | Live translation | 70+ → 13 languages |
| GPT‑Realtime‑Whisper | Streaming STT | Transcribe as speech happens |
- Surface: Realtime API (WebRTC/WebSocket/SIP-style voice stacks)—API-first, not a ChatGPT consumer Voice rebrand.
- Positioning: Voice as an agent interface—reason, translate, and transcribe in the loop—not only turn-based chat TTS.
Why this story matters
May already had GPT‑5.5 Instant as the ChatGPT default (May 5). Realtime‑2 is the parallel story for builders: speech-to-speech agents with flagship-class reasoning and first-class translate/transcribe companions. That is infrastructure for phone agents, multilanguage support, and low-latency apps—distinct from consumer ChatGPT Voice.
