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
59,400
1 output token counts as
4 input tokens
Smallest Global deployment
$3,900 / month reserved
Fully used PTU, per 1M tokens
$0.100

"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.

Prompts over 128K tokens aren't supported on provisioned deployments.

Worked example

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

Standard (Global)$270.00
Batch$135.00
Provisioned, hourly$10,950
Provisioned, 1-month reservation$3,900
Provisioned, 1-year reservation$3,315

PTUs: peak 184,932 normalized tokens a minute → 15 PTUs, about 7% used on average.

Frequently asked questions

How much does GPT-4.1 nano cost on Azure OpenAI?

On a Global Standard deployment, $0.100 per million input tokens and $0.400 per million output tokens, with cached input at $0.025 per million. Data Zone costs about 10% more and Batch about half. Prices are USD list prices.

How many PTUs does GPT-4.1 nano need?

At least 15 PTUs on Global or Data Zone (then steps of 5) and 25 on Regional. Each PTU handles 59,400 input tokens a minute, and one output token counts as 4 input tokens.

When is PTU cheaper than pay-as-you-go for GPT-4.1 nano?

A fully used Global PTU on a 1-month reservation costs about $0.100 per million normalized tokens, against $0.100 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.
