 - Generally Available (GA) model versions will be available for a minimum of 12 months.
 - After 12 months, existing customers may continue to use older model versions for an additional six months.
-- New customers who have never deployed the older model version will no longer have access after 12 months.
+- New customers who have never deployed the older model version in the same Azure subscription will no longer have access after 12 months.
 - For global deployments, all future model versions starting with `gpt-4o` and `gpt-4 0409` will be available with their (`N`) next succeeding model (`N+1`) for comparison together.
 - Customers have 60 days to try out a new GA model in at least one global or standard region before any upgrades happen to a newer GA model.
 
 ### Terminology
 
-- **Deprecation**: When a model is deprecated, it's no longer available for new customers. It continues to be available for use by customers who have existing deployments until the model is retired.

 - **Retirement**: When a model is retired, it's no longer available for use. Azure OpenAI deployments of a retired model always return error responses.

+If a customer has deployed a model version in Subscription A before the deprecation date,and later creates a new Subscription B under the same tenant after the deprecation date,Subscription B is considered a new customer and cannot deploy the deprecated model version.
