@Mohamed Hussein Different catalog models can have different pricing and subscription costs. This is usually displayed at the time of deploying the model from the model catalog page. In this case for hugging face, all models are listed to be deployed under managed compute, so the cost of deploying the model and calling the endpoint is based on how a real time endpoint is billed. So, if you have a hugging face endpoint the billing will use the credit or get billed under your pay as you go account.
Some services are not always free and do not use credit, you will have to check the list of services here before planning to use them. I hope this clarifies.
