+# Scaleway 
+LiteLLM supports all [models available on Scaleway Generative APIs ↗](https://www.scaleway.com/en/docs/generative-apis/reference-content/supported-models/). 
+
+## Usage with LiteLLM Python SDK
+
+```python
+import os
+from litellm import completion 
+
+os.environ["SCW_SECRET_KEY"] = "your-scaleway-secret-key"
+
+messages = [{"role": "user", "content": "Write a short poem"}]
+response = completion(model="scaleway/qwen3-235b-a22b-instruct-2507", messages=messages)
+print(response)
+```
+
+## Usage with LiteLLM Proxy 
+
+### 1. Set Scaleway models in config.yaml
+
+```yaml
+model_list:
+  - model_name: scaleway-model
+    litellm_params:
+      model: scaleway/qwen3-235b-a22b-instruct-2507
+      api_key: "os.environ/SCW_SECRET_KEY" # ensure you have `SCW_SECRET_KEY` in your .env
+```
+
+### 2. Start proxy 
+
+```bash
+litellm --config config.yaml
+```
+
+### 3. Query proxy 
+
+Assuming the proxy is running on [http://localhost:4000](http://localhost:4000):
+```bash
+curl http://localhost:4000/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer YOUR_LITELLM_MASTER_KEY" \
+  -d '{
+    "model": "scaleway-model",
+    "messages": [
+      {
+        "role": "system",
+        "content": "You are a helpful assistant."
+      },
+      {
+        "role": "user",
+        "content": "Write a short poem"
+      }
+    ]
+  }'
+```
+`-H "Authorization: Bearer YOUR_LITELLM_MASTER_KEY" ` is only required if you have set a LiteLLM master key
+
+
