A What it is for

Audio tokens $10 in / $20 out — the cheapest audio-out model OpenAI serves.

At a three-to-one input-to-output ratio, GPT-Audio Mini costs $1.05 per million tokens blended. A workload of one million input and 330,000 output tokens per day would run about $41.76 per month at list price, before caching or batch discounts.
