61:+## Creating Chat Completions
62:+**Here’s an improved example of creating chat completions:**
63:+```python
64:+response = client.chat.completions.create(
65:+    model="gpt-4o-mini",
66:+    messages=[
67:+        {
68:+            "role": "user",
69:+            "content": "Say this is a test"
70:+        }
71:+    ]
72:+    # Add any other necessary parameters
73:+)
74:+```
75:+
76:+**This example:**
77:+   - Asks a specific question `Say this is a test`
78:+   - Configures various parameters like temperature and max_tokens for more control over the output
79:+   - Disables streaming for a complete response
80:+
81:+You can adjust these parameters based on your specific needs.
