OpenAI brings GPT-5-level reasoning to its speech models

OpenAI launched three new speech-focused models: GPT-Realtime-2, its first voice model with GPT-5-class reasoning; GPT-Realtime-Translate for live translations; and GPT-Realtime-Whisper for fast transcriptions. GPT-Realtime-2 offers 11% performance improvement, extended context window to 128k tokens, parallel tool calls, and adjustable reasoning effort. Pricing remains the same as GPT-Realtime-1.5. The translation model supports 70+ input languages and 13 output languages, priced at $0.034/minute. The transcription model costs $0.017/minute. OpenAI also highlighted three patterns for voice AI: voice-to-action, system-to-voice, and voice-to-voice.
