trying to deploy graphrag-accelerator on a trial subscription, vm size errors

Question

trying to deploy graphrag-accelerator and keep getting vm size errors. I used gpt-4o in my deployment instead of 4 turbo because I wasn't able to deploy 4 turbo, I guess because of my subscription level? just want some clarification on this, and want to see if your graphrag will work for my use case. I obviously don't want to spend money on subscription upgrades until I know it will be useful in my context
