Provisioned throughput (PTU)

Deployment parameters from Microsoft Learn.

Global / Data Zone minimum
15 PTU, steps of 5
Regional minimum
50 PTU, steps of 50
Input tokens / min per PTU
3,000
1 output token counts as
4 input tokens
Smallest Global deployment
$3,900 / month reserved
Fully used PTU, per 1M tokens
$1.98

"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.

PTUs: peak 184,932 normalized tokens a minute → 65 PTUs, about 32% used on average.

Frequently asked questions

How much does GPT-4.1 cost on Azure OpenAI?

On a Global Standard deployment, $2.00 per million input tokens and $8.00 per million output tokens, with cached input at $0.500 per million. Data Zone costs about 10% more and Batch about half. Prices are USD list prices.

How many PTUs does GPT-4.1 need?

At least 15 PTUs on Global or Data Zone (then steps of 5) and 50 on Regional. Each PTU handles 3,000 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?

A fully used Global PTU on a 1-month reservation costs about $1.98 per million normalized tokens, against $2.00 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.
