+# Custom Pricing - Sagemaker, etc. 
+
+Use this to register custom pricing (cost per token or cost per second) for models. 
+
+## Quick Start 
+
+Register custom pricing for sagemaker completion + embedding models. 
+
+For cost per second pricing, you **just** need to register `input_cost_per_second`. 
+
+**Step 1: Add pricing to config.yaml**
+```yaml
+model_list:
+  - model_name: sagemaker-completion-model
+    litellm_params:
+      model: sagemaker/berri-benchmarking-Llama-2-70b-chat-hf-4
+      input_cost_per_second: 0.000420
+  - model_name: sagemaker-embedding-model
+    litellm_params:
+      model: sagemaker/berri-benchmarking-gpt-j-6b-fp16
+      input_cost_per_second: 0.000420
+```
+
+**Step 2: Start proxy**
+
+```bash
+litellm /path/to/config.yaml
+```
+
+**Step 3: View Spend Logs**
