Real-World Examples

Example 1: API Endpoint Creation

Prompt: “Create a FastAPI endpoint for user registration with email validation”

Codemium AI Output (87.2% accuracy):

from fastapi import FastAPI, HTTPException
from pydantic import BaseModel, EmailStr
from passlib.context import CryptContext
import re

app = FastAPI()
pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

class UserRegistration(BaseModel):
    email: EmailStr
    password: str
    username: str

@app.post("/register")
async def register_user(user: UserRegistration):
    # Password validation
    if len(user.password) < 8:
        raise HTTPException(status_code=400, detail="Password must be at least 8 characters")
    
    # Username validation
    if not re.match("^[a-zA-Z0-9_]{3,20}$", user.username):
        raise HTTPException(status_code=400, detail="Invalid username format")
    
    # Hash password
    hashed_password = pwd_context.hash(user.password)
    
    # Save to database (pseudo-code)
    # db.users.insert({"email": user.email, "password": hashed_password, "username": user.username})
    
    return {"message": "User registered successfully", "username": user.username}

Example 2: Algorithm Optimization

Prompt: “Optimize this bubble sort function”

Codemium AI Output (Performance: 98.3% improvement):

def optimized_sort(arr):
    """Optimized sorting using Timsort (Python's built-in)"""
    return sorted(arr)  # O(n log n) vs O(n²)

# Or if you need in-place sorting:
def optimized_bubble_sort(arr):
    """Improved bubble sort with early termination"""
    n = len(arr)
    for i in range(n):
        swapped = False
        for j in range(0, n - i - 1):
            if arr[j] > arr[j + 1]:
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
                swapped = True
        if not swapped:  # Early termination
            break
    return arr

Example 3: Bug Detection

Prompt: “Find the bug in this code: if user.age > 18 and user.age < 65:”

Codemium AI Output:

# Bug: Excludes users exactly 18 or 65 years old
# Fixed version:
if 18 <= user.age <= 65:  # More Pythonic and inclusive
    # Process user
    pass

# Or explicitly:
if user.age >= 18 and user.age <= 65:
    # Process user
    pass

Performance Tips

1. Hardware Optimization

# Enable GPU acceleration
export OLLAMA_GPU_LAYERS=999

# Adjust context size for speed/accuracy trade-off
ollama run Jayasimma/codemium_ai --ctx-size 4096

2. Prompt Engineering

Generic Prompt:

Write a function

Optimized Prompt:

Write a Python function named 'calculate_discount' that:
- Takes price (float) and discount_percent (int) as parameters
- Returns the discounted price rounded to 2 decimals
- Raises ValueError if discount > 100 or < 0
- Includes type hints and docstring

3. Batch Processing

# Process multiple requests efficiently
prompts = [
    "Write a binary search function",
    "Create a linked list class",
    "Implement quicksort algorithm"
]

# Parallel processing
from concurrent.futures import ThreadPoolExecutor

with ThreadPoolExecutor(max_workers=3) as executor:
    results = list(executor.map(ask_codemium, prompts))
