SmartGraph makes it easy to integrate powerful AI assistants into your applications using the CompletionComponent. This component allows you to leverage large language models (LLMs) like GPT-4 or Claude to create intelligent, context-aware applications. In this guide, we’ll explore how to effectively use the CompletionComponent to build sophisticated AI assistants.

​
Basic Usage

To get started with AI assistants in SmartGraph, you’ll use the CompletionComponent. Here’s a simple example: 
import asyncio
import os
from dotenv import load_dotenv
from smartgraph.components import CompletionComponent
from smartgraph.logging import SmartGraphLogger

# Load environment variables
load_dotenv()

# Set up logging
logger = SmartGraphLogger.get_logger()
logger.set_level("INFO")

async def main():
    # Create a CompletionComponent
    completion = CompletionComponent(
        "AI_Completion",
        model="claude-3-haiku-20240307",
        temperature=0.7,
        api_key=os.getenv("ANTHROPIC_API_KEY"),
    )

    user_input = "Explain reactive programming"
    logger.info(f"Processing input: {user_input}")

    try:
        result = await completion.process({"message": user_input})

        if "error" in result:
            logger.error(f"Error during processing: {result['error']}")
            print(f"\nAn error occurred: {result['error']}\n")
        else:
            logger.info(f"Received: {result}")
            print(f"\nAI Response: {result.get('ai_response', 'No response')}\n")

    except Exception as e:
        logger.error(f"Unexpected error during processing: {str(e)}", exc_info=True)
        print(f"\nAn unexpected error occurred: {str(e)}\n")

if __name__ == "__main__":
    asyncio.run(main())
In this example, we create a simple AI assistant that can answer questions about reactive programming.

​
Customizing the AI Assistant

The CompletionComponent offers several customization options:

​
Model Selection

Choose the AI model you want to use: 
CompletionComponent(
    "AI_Completion",
    model="claude-3-haiku-20240307",
    api_key=os.getenv("ANTHROPIC_API_KEY"),
)

​
Temperature

Control the randomness of the AI’s responses: 
CompletionComponent(
    "CreativeAssistant",
    model="claude-3-haiku-20240307",
    temperature=0.8,  # Higher temperature for more creative responses
    api_key=os.getenv("ANTHROPIC_API_KEY"),
)

​
Streaming Responses

Enable streaming for real-time responses: 
CompletionComponent(
    "StreamingAssistant",
    model="claude-3-haiku-20240307",
    stream=True,
    api_key=os.getenv("ANTHROPIC_API_KEY"),
)

​
Advanced Usage

​
Integrating External Knowledge

Enhance your AI assistant with external knowledge using the DuckMemoryToolkit: 
import asyncio
import os
from dotenv import load_dotenv
from smartgraph.components import CompletionComponent
from smartgraph.tools.duck_memory_toolkit import DuckMemoryToolkit
from smartgraph.logging import SmartGraphLogger

# Load environment variables
load_dotenv()

# Set up logging
logger = SmartGraphLogger.get_logger()
logger.set_level("INFO")

async def main():
    # Initialize DuckMemoryToolkit
    memory_toolkit = DuckMemoryToolkit("assistant_memory.duckdb")

    # Create a CompletionComponent with DuckMemoryToolkit
    completion = CompletionComponent(
        "AI_Completion",
        model="claude-3-haiku-20240307",
        temperature=0.7,
        api_key=os.getenv("ANTHROPIC_API_KEY"),
        toolkits=[memory_toolkit],
    )

    # Add some initial knowledge
    await memory_toolkit.add_memory("python", {"language": "Python", "type": "Programming language", "creator": "Guido van Rossum"})

    user_input = "Tell me about Python and its creator"
    logger.info(f"Processing input: {user_input}")

    try:
        result = await completion.process({"message": user_input})

        if "error" in result:
            logger.error(f"Error during processing: {result['error']}")
            print(f"\nAn error occurred: {result['error']}\n")
        else:
            logger.info(f"Received: {result}")
            print(f"\nAI Response: {result.get('ai_response', 'No response')}\n")

        # Store the interaction in memory
        await memory_toolkit.add_memory(f"interaction_{user_input}", {"question": user_input, "answer": result.get('ai_response', 'No response')})

    except Exception as e:
        logger.error(f"Unexpected error during processing: {str(e)}", exc_info=True)
        print(f"\nAn unexpected error occurred: {str(e)}\n")

if __name__ == "__main__":
    asyncio.run(main())
This setup allows the AI assistant to access and store information using the DuckMemoryToolkit, providing a way to maintain knowledge across sessions.

​
Best Practices

  1. API Key Security: Always use environment variables or secure key management systems for API keys.
  2. Error Handling: Implement robust error handling to manage potential issues with the AI service.
  3. Logging: Use the SmartGraphLogger for consistent logging across your application.
  4. Memory Management: When using memory toolkits, consider implementing a strategy for managing the growth of stored data.
  5. Rate Limiting: Implement rate limiting to avoid exceeding API quotas and manage costs.

​
Conclusion

The CompletionComponent in SmartGraph provides a powerful way to integrate AI assistants into your applications. By leveraging its features and following best practices, you can create sophisticated, context-aware AI applications that enhance user experiences and automate complex tasks.
