    • DeepSeek 2025: Build Your First AI App in 1 Hour

    Step 1: Setting Up DeepSeek API

    What you'll do: Connect to DeepSeek's brain

    # Install the DeepSeek package
pip install deepseek-sdk

# Import and initialize (like starting a car)
from deepseek import DeepSeekClient

# Your unique password to access DeepSeek
API_KEY = "your-key-here"  
client = DeepSeekClient(api_key=API_KEY)

    Think of it like: Downloading an app and logging in.

    Step 2: Create a Real-Time Chat Assistant

    What you'll build: A ChatGPT-style chatbot

    # Simple chat program
while True:
  user_input = input("You: ")
  
  # Get DeepSeek's response (like texting a friend)
  response = client.chat(
      message=user_input,
      model="deepseek-chat"
  )
  
  print(f"AI: {response['content']}")

    Sample Output:

    You: How does photosynthesis work?
AI: Photosynthesis is the process plants use to convert sunlight into energy...

    Step 3: Teach DeepSeek New Skills (Model Fine-Tuning)

    Example: Make it write cooking recipes

    # Prepare training data (like flashcards)
training_data = [
  {"input": "Make pizza", "output": "1. Mix flour... bake at 450°F"},
  {"input": "Chocolate cake", "output": "Preheat oven to 350°F..."}
]

# Train your custom chef model
custom_model = client.fine_tune(
  data=training_data,
  base_model="deepseek-v5",
  model_name="MyChefBot"
)

    Analogy: Teaching a pet new tricks with practice.

    Step 4: Deploy Your AI (Docker Example)

    What is Docker? A shipping container for apps

    # Dockerfile
FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "my_ai_app.py"]

    Build & Run:

    docker build -t my-ai-app .
docker run -p 5000:5000 my-ai-app
