OpenAI whisper-1, tts-1, tts-1-hd, gpt-4o-transcribe deprecated — removals Jan/Feb 2027
Transcription -> gpt-live-transcribe or gpt-transcribe. TTS -> gpt-realtime-2.1-mini (OpenAI points to the Realtime API guide for TTS migration). Plan the migration now; the replacement for TTS is a different API surface.
Symptom
Speech code defaults to whisper-1 for transcription and tts-1 for speech, the standard models in older examples.
