+# Request Tags for Spend Tracking
+
+Add tags to model deployments to track spend by environment, AWS account, or any custom label.
+
+Tags appear in the `request_tags` field of LiteLLM spend logs.
+
+## Config Setup
+
+Set tags on model deployments in `config.yaml`:
+
+```yaml title="config.yaml"
+model_list:
+  - model_name: gpt-4
+    litellm_params:
+      model: azure/gpt-4-prod
+      api_key: os.environ/AZURE_PROD_API_KEY
+      api_base: https://prod.openai.azure.com/
+      tags: ["AWS_IAM_PROD"]  # 👈 Tag for production
+
+  - model_name: gpt-4-dev
+    litellm_params:
+      model: azure/gpt-4-dev
+      api_key: os.environ/AZURE_DEV_API_KEY
+      api_base: https://dev.openai.azure.com/
+      tags: ["AWS_IAM_DEV"]  # 👈 Tag for development
+```
+
+## Make Request
+
+Requests just specify the model - tags are automatically applied:
+
+```bash
+curl -X POST 'http://0.0.0.0:4000/chat/completions' \
+  -H 'Authorization: Bearer sk-1234' \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "model": "gpt-4",
+    "messages": [{"role": "user", "content": "Hello"}]
+  }'
+```
+
+## Spend Logs
+
+The tag from the model config appears in `LiteLLM_SpendLogs`:
+
+```json
+{
+  "request_id": "chatcmpl-abc123",
+  "request_tags": ["AWS_IAM_PROD"],
+  "spend": 0.002,
+  "model": "gpt-4"
+}
+```
