Collection notes
Pay as you go only. The two plans are the model lines with a per-minute price in the "Estimated cost" column and no token price: whisper-1 for recorded audio ($0.006 a minute) and gpt-live-transcribe for live audio ($0.017 a minute). The token-billed models (gpt-4o-transcribe, gpt-4o-mini-transcribe, gpt-4o-transcribe-diarize) show only an estimated per-minute cost next to token prices and are not modelled. The MCP server is the documentation MCP server: it searches and reads the developer docs and has no transcription tools.

Existing integrations can use the deprecated `gpt-4o-transcribe-diarize` model to identify who speaks during different parts of a recording until February 26, 2027.
This specialized speaker-labeling model isn't the recommended model for ordinary file transcription.
Speaker labels need the separate gpt-4o-transcribe-diarize model, which is billed by tokens with only an estimated per-minute cost; the plans recorded do not state diarization. The guide of 2026-10-21 calls the model deprecated (shutdown February 26, 2027), says existing integrations can use it until then and that it is not the recommended model for ordinary file transcription; it does not say whether a new account can still start using it.
No sentence on the pages read states a minimum billed duration or per-request rounding.
