 # Plan to manage costs for model inference in Azure AI Services
 
-This article describes how you can plan for and manage costs for model inference in Azure AI Services. After you start using model inference in Azure AI Services resources, use **Cost Management features** to set budgets and monitor costs.

 ## Understand model inference billing model
 
-Models deployed in Azure AI Services are charged per 1,000 tokens. Language models understand and process text by breaking it down into tokens. For reference, each token is roughly four characters for typical English text. Costs per token vary depending on which model series you choose. Models that can process images break down images in tokens too. The number of tokens per image depends on the model and the resolution of the input image.
+Language models understand and process inputs by breaking them down into tokens. For reference, each token is roughly four characters for typical English text. Models that can process images or audio break down them into tokens too for billing purposes. The number of tokens per image or audio content depends on the model and the resolution of the input.
 
-Token costs are for both input and output. For example, suppose you have a 1,000 token JavaScript code sample that you ask a model to convert to Python. You would be charged approximately 1,000 tokens for the initial input request sent, and 1,000 more tokens for the output that is received in response for a total of 2,000 tokens.

-In practice, for this type of completion call, the token input/output wouldn't be perfectly 1:1. A conversion from one programming language to another could result in a longer or shorter output depending on many factors. One such factor is the value assigned to the `max_tokens` parameter.

 ### Provider models
 
-Models provided by another provider, like Mistral AI, Cohere, Meta AI, or AI21 Labs, are billed using Azure Marketplace. As opposite to Microsoft billing meters, those entries are associated with the resource group where your Azure AI services is deployed instead of to the Azure AI Services resource itself. You see entries under the **Service Name** *SaaS* accounting for inputs and outputs for each consumed model.

 ## Monitor costs
 
 Azure resource usage unit costs vary by time intervals, such as seconds, minutes, hours, and days, or by unit usage, such as bytes and megabytes. As soon as Azure AI services use starts, costs can be incurred and you can see the costs in the [cost analysis](/azure/cost-management/quick-acm-cost-analysis?WT.mc_id=costmanagementcontent_docsacmhorizontal_-inproduct-learn).

 You can also [export your cost data](/azure/cost-management-billing/costs/tutorial-export-acm-data?WT.mc_id=costmanagementcontent_docsacmhorizontal_-inproduct-learn) to a storage account, which is helpful when you need others to do extra data analysis for costs. For example, a finance team can analyze the data using Excel or Power BI. You can export your costs on a daily, weekly, or monthly schedule and set a custom date range. We recommend exporting cost data as the way to retrieve cost datasets.
