How it works
- How is transcription cost calculated?
- Cost = minutes × official Estimated cost $/min. Example: gpt-transcribe at $0.0045/min × 1,000 minutes → $4.50.
- Which model should I pick?
- gpt-transcribe ~$0.0045/min; gpt-4o-transcribe and diarize ~$0.006; mini ~$0.003; live-transcribe and realtime-whisper ~$0.017; realtime-translate ~$0.034; Whisper ~$0.006. Some rows also list $/1M tokens—this page uses the Estimated cost column.
- How does this differ from Realtime voice?
- Transcription is speech-to-text (and live translate). Realtime voice bills conversational audio tokens / GPT-Live minutes. Use the Realtime and Gemini Live calculators for dialogue.
- Is diarization priced differently?
- gpt-4o-transcribe-diarize shares the same ~$0.006/min estimated cost as gpt-4o-transcribe on the published table.
- Are results billing-grade?
- No. Estimates only; official OpenAI Transcription pricing prevails.
