Head-to-head, OpenAI Whisper (API) holds OpenAI gpt-4o-transcribe to a tie for dictation, medical and self-hosted.

Overall verdict: OpenAI gpt-4o-transcribe wins three use cases outright and ties the rest, giving it a clear overall edge. In Call Centers and Meetings, speaker diarization is included at no added tier, while OpenAI Whisper (API) offers no diarization at all. For Voice Agents, the WebSocket streaming API is decisive: gpt-4o-transcribe supports real-time streaming whereas Whisper (API) does not, making live conversational applications impractical on Whisper.
