# Terraform for setting up GPT-4, GPT-3.5-turbo, and text-embedding-ada-002
# endpoints. Note that not all models are available in all regions, so 
# check before changing the region here, currently set to "southcentralus"

# Assumes az-cli authenticated (requires Azure subscription) and terraform 
# available and installed
