@Gaurav Kumar AI studio is still a preview service and you need to apply for OpenAI access for complete usability of its features.
It has several additional resources which are deployed in your subscription. A detailed list of resource providers used is documented in the architecture page. Is this something you are looking for?
If you are looking for complete list of resources that are created with AI studio you can lookup the ARM template of basic AI studio deployment from this page. Thanks!!
