Leveraging the Power of Semantic Kernel with Groq: A Comprehensive Guide

Setting up and using the Semantic Kernel with the Groq API for chat completion tasks can significantly enhance the development of intelligent applications. Here's a step-by-step implementation with a detailed explanation.

Step 1: Import Necessary Libraries and Set Up Environment

First, we need to import the necessary libraries and set up the environment variable for the Groq API key.

import os
from openai import AsyncOpenAI
from semantic_kernel import Kernel
from semantic_kernel.connectors.ai.open_ai import OpenAIChatCompletion

# Set the Groq API key environment variable.
os.environ["OPENAI_API_KEY"] = "your_groq_api_key_here"
API_KEY = os.getenv("OPENAI_API_KEY")        

Explanation:

- os: Used to set environment variables.

- AsyncOpenAI: Client to interact with the OpenAI API.

- Kernel and OpenAIChatCompletion: Components from Semantic Kernel to manage and execute chat completion tasks.

Replace "your_groq_api_key_here" with your actual Groq API key.

Step 2: Initialize the AsyncOpenAI Client and Kernel

Next, we initialize the AsyncOpenAI client with the Groq API base URL and the kernel.

# Initialize the AsyncOpenAI client with the Groq API base URL.
client = AsyncOpenAI(api_key=API_KEY, base_url="https://api.groq.com/openai/v1")

# Initialize the kernel.
kernel = Kernel()        

Explanation:

- client: An instance of AsyncOpenAI initialized with the API key and base URL pointing to Groq's endpoint.

- kernel: An instance of Kernel that will manage the services.

Step 3: Add the OpenAI Chat Completion Service to the Kernel

We then add the OpenAI chat completion service to the kernel, specifying the AI model ID and the client.

# Add the OpenAI chat completion service to the kernel.

kernel.add_service(OpenAIChatCompletion(
    ai_model_id="Llama3-70b-8192",
    async_client=client
))        

Explanation:

- ai_model_id: The ID of the AI model to be used for chat completion.

- async_client: The initialized AsyncOpenAI client.

Step 4: Retrieve the Chat Completion Service

We retrieve the chat completion service from the kernel.

# Retrieve the chat completion service from the kernel.

from semantic_kernel.connectors.ai.chat_completion_client_base import ChatCompletionClientBase

chat_completion_service = kernel.get_service(type=ChatCompletionClientBase)        

Explanation:

- ChatCompletionClientBase: The base class for chat completion clients.

- chat_completion_service: The service retrieved from the kernel.

Step 5: Define Execution Settings

Define the execution settings for the chat completion service.

# Define the execution settings for the chat completion service.

from semantic_kernel.connectors.ai.open_ai import OpenAIChatPromptExecutionSettings

execution_settings = OpenAIChatPromptExecutionSettings(
    service_id=None,
    max_tokens=500,
    temperature=0.1
)        

Explanation:

- OpenAIChatPromptExecutionSettings: Settings for the chat completion service.

- max_tokens: Maximum number of tokens for the generated response.

- temperature: Controls the randomness of the response.

Step 6: Create Chat History and Add Initial Messages

Create a chat history instance and add initial messages to simulate a conversation.

# Create a chat history instance and add initial messages.

from semantic_kernel.contents.chat_history import ChatHistory

chat_history = ChatHistory()

chat_history.add_system_message("You are a helpful assistant that follows exactly what user says. Be precise, friendly, and coherent.")
chat_history.add_user_message("Write a code snippet in C to print 'hello world.'")        

Explanation:

- ChatHistory: Manages the history of the chat.

- add_system_message: Adds a system message to set the chatbot's behavior.

- add_user_message: Adds a user message to prompt the chatbot.

Step 7: Generate a Response Using the Chat Completion Service

Finally, generate a response using the chat completion service and print it.

# Generate a response using the chat completion service.

response = (await chat_completion_service.get_chat_message_contents(
    chat_history=chat_history,
    kernel=kernel,
    settings=execution_settings
))[0]

print(response)        

Explanation:

- get_chat_message_contents: Generates a response based on the chat history and execution settings.

- response: The generated response is printed.

Additional Note

For a more detailed example, I have shared this Colab notebook with the code explained above.

By following these steps, you can effectively set up and use the Semantic Kernel with the Groq API for chat completion tasks, unlocking the potential for advanced AI-driven applications.
