 Azure Cosmos DB free tier makes it easy to get started, develop, test your applications, or even run small production workloads for free. When free tier is enabled on an account, you'll get the first 1000 RU/s and 25 GB of storage in the account for free. The throughput and storage consumed beyond these limits are billed at regular price. Free tier is available for all API accounts with provisioned throughput, autoscale throughput, single, or multiple write regions.
 
-Free tier lasts indefinitely for the lifetime of the account and it comes with all the [benefits and features](introduction.md#an-ai-database-with-unmatched-reliability-and-flexibility) of a regular Azure Cosmos DB account. These benefits include unlimited storage and throughput (RU/s), SLAs, high availability, turnkey global distribution in all Azure regions, and more.

 You can have up to one free tier Azure Cosmos DB account per an Azure subscription and you must opt in when creating the account. If you don't see the option to apply the free tier discount, another account in the subscription has already been enabled with free tier. If you create an account with free tier and then delete it, you can apply free tier for a new account. When creating a new account, it’s recommended to enable the free tier discount if it’s available.
