Provisioned throughput (PTU)

Deployment parameters from Microsoft Learn.

Global / Data Zone minimum
15 PTU, steps of 5
Regional minimum
25 PTU, steps of 25
Input tokens / min per PTU
2,500
1 output token counts as
4 input tokens
Smallest Global deployment
$3,900 / month reserved
Fully used PTU, per 1M tokens
$2.37

"Fully used" is the 1-month Global reservation divided by everything one PTU can process in a month, in normalized tokens. Real deployments are sized for peak and run below that on average.

Worked example

1M requests a month, 1,500 input and 300 output tokens each, peak 3× the average, Global deployment.

Standard (Global)$2,970
Batch$1,485
Provisioned, hourly$54,750
Provisioned, 1-month reservation$19,500
Provisioned, 1-year reservation$16,575

PTUs: peak 184,932 normalized tokens a minute → 75 PTUs, about 33% used on average.

Frequently asked questions

How much does o3-mini cost on Azure OpenAI?

On a Global Standard deployment, $1.10 per million input tokens and $4.40 per million output tokens, with cached input at $0.550 per million. Data Zone costs about 10% more and Batch about half. Prices are USD list prices.

How many PTUs does o3-mini need?

At least 15 PTUs on Global or Data Zone (then steps of 5) and 25 on Regional. Each PTU handles 2,500 input tokens a minute, and one output token counts as 4 input tokens.

When is PTU cheaper than pay-as-you-go for o3-mini?

A fully used Global PTU on a 1-month reservation costs about $2.37 per million normalized tokens, against $1.10 per million input tokens on Standard. Real deployments are sized for peak load and run well below 100% on average, so Standard is usually cheaper unless the load is high and steady.
