Whisper Gives Way to Realtime Transcription

Transcription AI has shifted from Whisper as a standalone baseline to a split market: model infrastructure on one side and polished dictation UX on the other. OpenAI's speech-to-text docs now include gpt-4o-transcribe, gpt-4o-mini-transcribe, and gpt-4o-transcribe-diarize, and the May 7, 2026 GPT-Realtime-Whisper launch points to live transcription as the current focus. For end users, the momentum is in workflow-first dictation tools rather than raw ASR benchmarks.
