GPT Audio Mini: pricing, context and benchmarks
GPT Audio Mini is a language model from OpenAI released on January 19, 2026. It costs $0.6 per million input tokens and $2.4 per million output tokens, with a 128K-token context window. No independent score has been published for it so far.
What you need to know about GPT Audio Mini
GPT Audio Mini was released by OpenAI (United States) on January 19, 2026. It accepts text and audio as input and produces text and audio. Its context window reaches 128,000 tokens, larger than 19 % of the models in the registry, and it can write up to 16,384 tokens in one go.
It has been available for about 9 months, long enough for its prices and scores to have settled.
GPT Audio Mini pricing
On OpenRouter, GPT Audio Mini costs $0.6 per million input tokens and $2.4 per million output tokens. Counting three tokens read for every token written, its average price is $1.05 per million, more expensive than 59 % of paid models (1.4 times the median of $0.76).
A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0024. At 1,000 tasks a day, budget $72 a month. The price calculator redoes this with your own volumes.
Performance and benchmarks
Epoch AI does not yet publish a capabilities index for GPT Audio Mini. We therefore show no made-up performance rating: only price, context and features count towards its score.
Features, privacy and local use
- It supports tool calling, so it can drive an AI agent, call APIs or MCP servers.
- It can answer in an enforced JSON format (structured outputs).
Its weights are not published: it can only be used through the OpenAI API or a broker such as OpenRouter, which means sending your data off your machines.
