Azure OpenAI Service pricing

Azure OpenAI Service pricing overview

Unlock the power of large-scale, generative AI models with Azure OpenAI Service, offering the flexibility of both Pay-As-You-Go (PAYG) and Provisioned Throughput Units (PTUs). With PAYG, you can optimise costs by paying only for the resources you use, while PTUs provide throughput with minimal latency variance, making them ideal for scaling your AI solutions. Each model is priced per unit, ensuring a predictable cost structure for your AI deployments. Contact a sales specialist for personalised assistance in understanding how PAYG and PTUs can optimise your AI deployments and pricing.

Prices are estimates only and are not intended as actual price quotes. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate. Prices are calculated based on US dollars and converted using London closing spot rates that are captured in the two business days prior to the last business day of the previous month end. If the two business days prior to the end of the month autumn on a bank holiday in major markets, the rate setting day is generally the day immediately preceding the two business days. This rate applies to all transactions during the forthcoming month. Sign in to the Azure pricing calculator to see pricing based on your current programme/offer with Microsoft. Contact an Azure sales specialist for more information on pricing or to request a price quote. See frequently asked questions about Azure pricing.

Assistants API

Tool Input
Code Interpreter $-/session

Inference cost (input and output) varies based on the GPT model used with each Assistant. If your assistant calls Code Interpreter simultaneously in two different threads, this would create two Code Interpreter sessions (2 * $-). Each session is active by default for one hour, which means that you would only pay this fee once if your user keeps giving instructions to Code Interpreter in the same thread for up to one hour.

  • Azure OpenAI Service offers pricing based on both Pay-As-You-Go and Provisioned Throughput Units (PTUs). Pay-As-You-Go allows you to pay for the resources you consume, making it flexible for variable workloads. PTUs offers a predictable pricing model where you reserve and deploy a specific amount of model processing capacity. This model is ideal for workloads with consistent or predictable usage patterns, providing stability and cost control.
  • To learn more about PTUs and Azure Open AI pricing please read PTU documentation or contact our sales specialist
