Hi @Janos Perczel
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
You can't seem to figure out the detailed cost of storing your optimized model because your current Azure subscription doesn't support cost analysis features. This is common for certain types of subscriptions, such as free trials or low-cost plans.
If you’re open to it, moving up to a Pay-As-You-Go or higher tier subscription will give you more detailed analysis of payments and expenses.
You can still view all charges in the Billing section of the Azure portal. This will give you a general idea of how much you are being charged.
The Azure Pricing Calculator | Microsoft Azure can help you calculate what it will cost you to store your image.
If you need specific information, feel free to contact Azure support. You can be given a breakdown of your expenses based on your account.
If you are comfortable using command line tools, the Azure CLI is another way to track your usage and spend.
For reference, please review this documentation:-
