OpenAI Releases Three Realtime Audio Models: GPT-Realtime-2, GPT-Realtime-Translate, and GPT-Realtime-Whisper in the Realtime API

OpenAI released three new audio models via its Realtime API: GPT-Realtime-2 (voice reasoning agent), GPT-Realtime-Translate (live speech translation across 70+ languages), and GPT-Realtime-Whisper (streaming transcription). The Realtime API exits beta and becomes generally available. These models enable voice applications to listen, reason, translate, transcribe, and act within a single conversation, moving beyond basic Q&A loops.
