Our take
Written Sep 30, 2026GPT Audio is a hosted speech-to-speech model: audio goes in and audio comes back, so a spoken exchange does not have to be turned into writing first. We list no download for it, and nothing here measures how accurately it transcribes or how fast it runs, so treat it as a candidate to trial rather than a proven pick.
Reach for it when you want a spoken answer rather than a transcript, through a host. Its request capacity is large enough that long recordings need not be split up first, though reliable handling across all of it is unverified in our data. Skip it if you need measured transcription accuracy, a published language list, or a measured serving speed, none of which we hold.
The case for it
- Both listed hosts charge the same rate, so the choice between them is not a price decision.
- Audio goes in and audio comes back, so a spoken exchange does not have to be turned into writing first.
The case against it
- Word error rate is unrecorded on clean read-aloud recordings, podcasts and video, accented speech and meeting recordings, so accuracy needs a trial on recordings you can check yourself.
- Neither offer carries a measured speed, so how quickly a long recording is handled is unverified in our data.
- No language list is held, and every accuracy figure we do hold is English only, so use in another language is untested here.
How good is it?
We hold no score for this model.
The Open ASR Leaderboard is where a model that turns speech into text gets measured, and GPT Audio is not on it — so we hold no accuracy figure for it, rather than a poor one.

OpenAI, direct
The lab is also the cheapest we hold. The strip above and this offer are the same one, so nothing on this page undercuts OpenAI on 128K of context.
