Our take
Written Aug 3, 2026GPT Audio Mini is a hosted-only speech-to-speech model from OpenAI that launched in January 2026. It can handle up to 128,000 tokens in a single request and is designed for voice interfaces where you need both audio input and audio output.
Pick this when you need speech-to-speech capability inside the OpenAI ecosystem, or when a voice interface must handle very long context. Skip it if you want measured accuracy, speed data, or language coverage — none of these are verified in our data, and the pricing sits at a premium with no performance evidence to justify it.
The case for it
- 128,000-token request limit, which is substantial for a speech model and the only concrete capability figure we hold.
- Hosted by two providers, giving a fallback option within the same price tier.
The case against it
- No measured accuracy, speed, or language coverage — every performance dimension is unverified in our data.
- Premium pricing with no benchmark scores or throughput figures to explain the cost; the second tracked host lists no throughput at all.
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 Mini is not on it — so we hold no accuracy figure for it, rather than a poor one.
Or rent it from someone else
Why this differs from the header. The strip above quotes OpenAI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.

Across the 2 listings we hold: 1 say they do not train on prompts, 0 say they do and 1 do not say. 0 appear in the zero-retention registry we check; the rest are unknown to us rather than confirmed either way.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
