it is unclear which is the correct Azure OpenAI model retirement date.

I was wondering if there is any documentation on https://XXX.openai.azure.com/openai/preprocessing-jobs?api-version=2023-03-31-preview endpoint? I noticed its getting used for the chat with your data functionality in the Azure open AI studio but I cant find anything on the internet regarding this endpoint? is it because is in preview? I noticed that there is a property within the skillset that gets output into something like this:

I am trying out Azure OpenAI with my own data. The data is uploaded to Azure Blob Storage and indexed for use with Azure AI search

I keep on getting charged an hourly rate for the Azure AI Search service even though I already deleted the service. I checked for the resource under the “All resources” tab and the service doesn’t exist anymore. Yet I’m still being charged 3-4 hours after deleting it.
