Source: Azure Retail Prices API, refreshed 15 Oct 2026. Data Zone and Regional prices for eastus2. "list": price not yet confirmed by the weekly refresh; Data Zone list prices are Global + 10%. GPT-5.5 is a reasoning model: its hidden reasoning tokens are billed as output.

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
1,200
1 output token counts as
6 input tokens
Smallest Global deployment
$3,900 / month reserved
Fully used PTU, per 1M tokens
$4.95

"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)—
Provisioned, hourly$138,700
Provisioned, 1-month reservation$49,400
Provisioned, 1-year reservation$41,990

PTUs: peak 226,027 normalized tokens a minute → 190 PTUs, about 33% used on average.

Frequently asked questions

How many PTUs does GPT-5.5 need?

At least 15 PTUs on Global or Data Zone (then steps of 5) and 50 on Regional. Each PTU handles 1,200 input tokens a minute, and one output token counts as 6 input tokens.
