GPT-5.1 Azure Pricing
OpenAI prices for Azure OpenAI GPT5 in Microsoft Foundry. Published rates cover 6 deployment profiles across 30 Azure Public price regions.
Prices by deployment type
All rates are USD per 1 million tokens. Each row uses its own deployment type and published price regions. A range reflects regional differences within that type. Missing prices mean no published meter in this snapshot; they do not mean free usage. A retail price does not guarantee deployment availability or quota.
| Deployment type | Input / 1M | Output / 1M | Cached input / 1M | Cache write / 1M | Price regions |
|---|---|---|---|---|---|
| Data Zone Batch | $0.6875 - $0.75 | $5.50 - $6.00 | $0.06875 - $0.075 | Not published | 23 |
| Data Zone Priority | $2.75 | $22.00 | $0.275 | Not published | 13 |
| Data Zone Standard | $1.375 - $1.50 | $11.00 - $12.00 | $0.1375 - $0.15 | Not published | 23 |

The tables contain only this OpenAI listing. Other providers, versions and similarly named Azure products can have different meters. Some token categories may be missing in individual regions; expand the regional tables for exact coverage.
How token costs are calculated
For each region and deployment type, multiply each token category by its matching rate, then divide the sum by 1,000,000. Monthly estimates multiply that request cost by the number of requests. Ranges use complete workloads priced in each region, so input and output prices from different regions are never combined.
Request cost = (uncached input tokens × input rate + cached input tokens × cached input rate + cache-write input tokens × cache-write rate + output tokens × output rate) / 1,000,000.
The examples below use zero cache writes. The cached example assumes half of the input tokens are eligible cache reads on every request; actual cache hit rates and any cache creation charges depend on the deployment. Missing cache rates are not replaced with ordinary input rates. Estimates cover these token meters only, before taxes, negotiated discounts and any separate hosting, tools, media or provisioned-capacity charges.
Data Zone Batch prices and cost examples
- Data Zone processing
- Inference data is processed within the Microsoft-specified US, EU, or APAC data zone.
- Asynchronous Batch
- Batch meters cover asynchronous jobs. Microsoft documents Global and Data Zone Batch at a 50% discount, with a 24-hour target for Global Batch; model support varies.
Example workload: 3,000 input and 1,000 output tokens per request, with 10,000 requests per month.
