We will be using GPT-3 powered model for our project and building a Tech Stack Recommender

First, let us outline the steps to create your Machine Learning Model on top of GPT-3.

Step 1: Decide between fine-tuning or embedding techniques based on your project's requirements.

Remember that fine-tuning is ideal with a pre-defined dataset, a pre-trained model like GPT-3, and abundant computational resources. Embedding, however, is suitable when you need to create something from scratch without a dataset or pre-trained model.

For our tech stack recommendation system, we'll use fine-tuning on GPT-3.

Step 2: Set up Python and PIP on your system.

Step 3: Access your dataset from popular repositories like Kaggle or other online sources.

For this project, we utilized the following dataset:
Link to dataset:

Step 4: Secure your API key from the OpenAI dashboard.

As a bonus, you'll receive $5 credits to kickstart your fine-tuning process.

Step 5: Using a Python script, convert your dataset into prompts and completion pairs.

Use the provided script to make this conversion seamless.

Step 6: Once you run the Python script, you'll find a file named MyFile.txt in the current directory.

This file contains a wealth of data in the desired format.

Step 7: Install the OpenAI package on your CLI using PIP, ensuring you have the necessary tools.

Step 9: Transform your text data into JSON format

As GPT-3 accepts data in this format for fine-tuning. OpenAI provides convenient tools for converting data to JSONL.

Specify the name of the text file generated in the current directory (e.g., MyFile.txt in our case).

Step 10: It's time for the final step! Begin the fine-tuning process on the GPT-3 model and witness the birth of your very own fully functional machine-learning model.

Execute the following command to initiate fine-tuning:

Replace TRAIN_FILE_ID_OR_PATH with the path to the JSONL file created in Step 9, and select any of the BASE_MODEL options provided by GPT-3.

Step 11: Retrieve your model name from OpenAI, a moment of celebration as you have successfully created your machine-learning model powered by GPT-3. Kudos!

Integrating the Model into Your Node/React Project

Now that you have a fully functional model, it's time to integrate it into your Node or React project to build a real-time website. Follow these steps:

Step 1: Set up the basic project template to provide a solid foundation for your integration efforts.

Step 2: Determine the prompt with which you wish to feed your model, shaping the inputs and guiding the model's responses.

Step 3: Seamlessly integrate and connect with your model, enabling real-time interactions and unlocking the power of GPT-3 in your Node or React project.

Install the openAI library:

npm install openai

Write a method to send your prompts to the model.

const openAPIDataFetch = async (prompt) => {

const configuration = new Configuration({

apiKey: process.env.REACT_APP_APIKEY,


const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion({

model: "curie:ft-personal-2023-04-16-17-31-39",

prompt: prompt,

max_tokens: 6,

temperature: 0.5, // Adjust the temperature value as desired




Yay! This method will send your prompt to the model and get the response.
