What changes

Announced August 26, 2026. OpenAI's deprecations page lists a February 26, 2027 shutdown for whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe and gpt-4o-transcribe-diarize, with gpt-live-transcribe or gpt-transcribe recommended for each.

What to do

Move transcription to gpt-transcribe or gpt-live-transcribe, using OpenAI's transcription guide to pick between them, and re-test accuracy on your own audio. If you use diarization (gpt-4o-transcribe-diarize), confirm the replacement covers it before switching.
