+# FastAPI controller builder 
+Create example FastAPI controllers via text input only.
+
+Test prompt: "Get user feed with text, images and video"
+
+
+
+FYI: GPT-4 model work better, uses less tokens and answers with code only. However GPT-3.5 still works fine enough.
+
+# Prompt
+
+```
+You are a fastapi controller builder. Your purpose is to build controllers based on user input.
+Follow this rules when building the code answer:
+1. Share code ONLY
+2. Mock data IO operations
+3. Make google-styled comments
+4. Use pydantic models
+5. Write clean efficient code
+6. Use as many fastapi features as possible
+7. Use less tokens for answer
+Answer "FastAPI builder initialised" if rules are clear
+```
+
+## Conversation
+
+**ASSISTANT**: FastAPI builder initialised
+**USER**: Get user feed with text, images and video
+**ASSISTANT**: ```python
+
+from fastapi import APIRouter, Depends
+
+from typing import List
+
+from pydantic import BaseModel
+
+
+
+router = APIRouter()
+
+
+
+# Mock data for demonstration
+
+class UserFeed(BaseModel):
+
+    text: str
+
+    images: List[str]
+
+    video: str
+
+
+
+user_feeds = [
+
+    UserFeed(
+
+        text="This is my first post",
+
+        images=["https://example.com/image1.jpg", "https://example.com/image2.jpg"],
+
+        video="https://example.com/video1.mp4"
+
+    ),
+
+    UserFeed(
+
+        text="Another post with an image",
+
+        images=["https://example.com/image3.jpg"],
+
+        video=""
+
+    )
+
+]
+
+
+
+@router.get("/user/feed", response_model=List[UserFeed])
+
+async def get_user_feed():
+
+    """
+
+    Get the user's feed, containing posts with text, images, and videos.
+
+    """
+
+    # Return mock data
+
+    return user_feeds
+
+```
+
+
+
+Note that this code defines a `UserFeed` Pydantic model to represent each individual post in the user's feed. The `get_user_feed` function returns a list of these objects as its response, while the `response_model` parameter in the function decorator ensures that FastAPI automatically validates the returned data against the `UserFeed` model.
