Regarding selecting the right model, it depends on your specific use case and what kind of task you want to perform. When you open each model, the description shows the details about model.

Regarding cost calculation, the cost of using Azure AI services is based on the number of transactions you perform. For example, if you use the GPT-3 model to generate text, each text generation would count as a transaction.
The cost of each transaction depends on the specific model you are using and the number of tokens or completions you are requesting. You can find more information about the pricing of different models in the Azure OpenAI Service pricing overview page.

- You should see a list of your usage and billing information.

You can also set up alerts to notify you when you reach a certain usage or cost threshold. See Plan and manage costs for Azure AI services.
