+# Structured Outputs (AOT)
+
+Get structured JSON responses using a JsonTypeInfo for AOT/trimming compatibility.
+
+This example assumes `using tryAGI.OpenAI;` is in scope and `apiKey` contains your tryAGI.OpenAI API key.
+
+```csharp
+using var client = new OpenAiClient(apiKey);
+
+var response = await client.Chat.CreateChatCompletionAsAsync(
+    jsonTypeInfo: SourceGeneratedContext.Default.WordsResponse,
+    messages: ["Generate five random words."],
+    model: "gpt-4o-mini");
+
+Console.WriteLine("Words:");
+foreach (var word in response.Value1!.Words)
+{
+    Console.WriteLine(word);
+}
+```
