[Manouchehri]

The Feature

It's undocumented, but 2024-08-01-preview supports "stream_options": {"include_usage": true}}.

Example:

export AZURE_OPENAI_AD_TOKEN=$(az account get-access-token --scope "https://cognitiveservices.azure.com/.default" --query accessToken --output tsv)

curl -v "https://RESOURCE_REMOVED.openai.azure.com/openai/deployments/DEPLOYMENT_REMOVED/chat/completions?api-version=2024-08-01-preview" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AZURE_OPENAI_AD_TOKEN" \
  -H "x-ms-client-request-id: tests-good-$RANDOM" \
  -d '{"messages":[{"role": "user", "content": "Hello."}], "max_tokens": 1, "temperature": 0.0, "seed": 42, "stream": true, "stream_options": {"include_usage": true}}'
