Building upon the answer from Gili.

Using the aws CLI and jq :

aws --region us-east-1 pricing get-products \
  --service-code AmazonSageMaker \
  --filters Type=TERM_MATCH,Field=regionCode,Value=eu-north-1 \
  | jq -r '.PriceList[]|fromjson|select(.product.productFamily == "ML Instance")|.product.attributes.instanceName'\
|sort\
|uniq

ml.c5.12xlarge
ml.c5.18xlarge
ml.c5.24xlarge
ml.c5.2xlarge
ml.c5.4xlarge
ml.c5.9xlarge
ml.c5.large
...
ml.t3.2xlarge
ml.t3.large
ml.t3.medium
ml.t3.xlarge

it uses

• aws pricing get-products
  • --region us-east-1 is important because the Pricing service is not widely available
  • --filters Type=TERM_MATCH,Field=regionCode,Values=eu-north-1 to restrict the listing to products in eu-north-1 region, the number of products for AmazonSageMaker alone across all regions is huge, so better to let AWS to filter out those early
• jq is used to further filter the output, it seems it's not possible to filter by productFamily at the aws pricing get-products so we need to do it with jq
  • -r removes the quotes from the output
  • .PriceList[] will iterate over all the prices returned by aws pricing get-products
  • fromjson will parse the each string as JSON (.PriceList is an array of strings)
  • select(.product.productFamily == "ML Instance") will filter out all other products
  • .product.attributes.instanceName extracts the instance type from each product.
