+
+LiteLLM provides native support for DigitalOcean GenAI models.
+To use a DigitalOcean model, specify it as `digitalocean/<model-name>` in your LiteLLM requests.
+
+
+## API Key & Endpoint
+
+Set your credentials and endpoint as environment variables:
+
+```python
+import os
+os.environ['DIGITALOCEAN_API_KEY'] = "your-api-key"
+os.environ['DIGITALOCEAN_AGENT_ENDPOINT'] = "https://api.digitalocean.com/api/v1/chat"  # default endpoint
+```
+
+## Sample Usage
+
+```python
+from litellm import completion
+import os
+
+os.environ['DIGITALOCEAN_API_KEY'] = "your-api-key"
+response = completion(
+    model="digitalocean/model-name",
+    messages=[
+        {"role": "user", "content": "Hello, how are you?"}
+    ],
+)
+print(response.choices[0].message.content)
+```
+
+## Streaming Example
+
+```python
+from litellm import completion
+import os
+
+os.environ['DIGITALOCEAN_API_KEY'] = "your-api-key"
+response = completion(
+    model="digitalocean/model-name",
+    messages=[
+        {"role": "user", "content": "Write a story about a robot learning to love"}
+    ],
+    stream=True,
+)
+
+for chunk in response:
+    print(chunk.choices[0].delta.content or "", end="")
+```
+
