Build Your Own Local ChatGPT with Ollama & Llama 3.1: A Python Quickstart Guide

Introduction

Chatbots have revolutionized the way we interact with technology, and with the rise of AI models like LLaMA 3.1 and Ollama, building a local chatbot has never been easier. In this article, we'll guide you through the process of creating a local chatbot using Python, Ollama, and LLaMA 3.1.

What You'll Need

• Python 3.8+
• Ollama API
• LLaMA 3.1 API
• A text editor or IDE (optional)

Step 1: Install Required Libraries

To get started, we'll need to install the required libraries. Run the following command in your terminal:

pip install python-ollama-api llama3

Step 2: Set Up Ollama API

First, we'll set up the Ollama API. Create a file called ollama_api.py with the following code:

import json
import requests

class OllamaAPI:
    def __init__(self, api_key):
        self.api_key = api_key
        self.base_url = "https://api.ollama.io/v1"

    def get_response(self, prompt):
        headers = {"Authorization": f"Bearer {self.api_key}"}
        response = requests.post(f"{self.base_url}/generate", headers=headers, json={"prompt": prompt})
        return response.json()

ollama_api = OllamaAPI("YOUR_OLLAMA_API_KEY")

Replace YOUR_OLLAMA_API_KEY with your actual Ollama API key.

Step 3: Set Up LLaMA 3.1 API

Next, we'll set up the LLaMA 3.1 API. Create a file called llama3_api.py with the following code:

import json
import requests

class LLaMA3API:
    def __init__(self):
        self.base_url = "https://api.llama3.io/v1"

    def get_response(self, prompt):
        response = requests.post(f"{self.base_url}/generate", json={"prompt": prompt})
        return response.json()

llama3_api = LLaMA3API()

Step 4: Integrate Ollama and LLaMA 3.1

Now, we'll integrate Ollama and LLaMA 3.1 to create a full-fledged chatbot. Create a file called chatbot.py with the following code:

import json
from ollama_api import ollama_api
from llama3_api import llama3_api

class Chatbot:
    def __init__(self):
        self.ollama_api = ollama_api
        self.llama3_api = llama3_api

    def get_response(self, prompt):
        ollama_response = self.ollama_api.get_response(prompt)
        llama3_response = self.llama3_api.get_response(prompt)
        return ollama_response, llama3_response

chatbot = Chatbot()
