Jargons 101 :


Before diving deeper into Generative AI, let’s acquaint ourselves with some fundamental terms and concepts. Navigating through the field requires understanding its unique jargon. Below, we’ll demystify common terms you’re likely to encounter:

  • Generative Models:

Generative models are algorithms within Generative AI designed to generate new data points resembling a given dataset. These models learn data patterns and structures to produce new samples.

  • Neural Networks:

Inspired by the human brain, neural networks are computational models comprising interconnected nodes or neurons arranged in layers. They serve as the backbone for many Generative AI algorithms.

  • Training:

Training is the process of instructing a machine learning model to execute a specific task by providing it with labeled data. During training, the model fine-tunes its parameters to minimize the disparity between its predictions and actual labels.

  • Loss Function:

A loss function quantifies a machine learning model’s performance on a given task by measuring the difference between its predictions and the true labels. It offers guidance for the training process. 

  • Gradient Descent:

Gradient descent is an optimization technique employed to minimize the loss function by iteratively adjusting the model’s parameters in the direction that diminishes the loss. It serves as a cornerstone in training neural networks.

  • Overfitting and Underfitting:

Overfitting arises when a machine learning model becomes too tailored to the training data, hindering its ability to generalize to new, unseen data. Conversely, underfitting occurs when the model is too simplistic to capture underlying data patterns.

These foundational concepts lay the groundwork for comprehending Generative AI’s intricacies.  

Basic NLP Refresher


Before delving deeper into Generative AI, let’s revisit the fundamentals of Natural Language Processing (NLP). NLP, a subset of artificial intelligence, focuses on the interaction between computers and human language. Below are key concepts to refresh your understanding:

  • Tokenization:

Tokenization is like breaking down a sentence into individual building blocks. Imagine you have a large dataset of customer reviews, and you want to analyze the sentiment of each review. Tokenization helps you break down each review into separate words or phrases, making it easier to analyze.

  • Part-of-Speech Tagging (POS Tagging):

POS tagging helps us understand the grammatical structure of a sentence. Let’s say you’re building a chatbot that needs to understand user queries. POS tagging can help the chatbot identify verbs, nouns, and other parts of speech, enabling it to respond more accurately.

  • Named Entity Recognition (NER):

NER is essential for extracting specific information from text. For example, if you’re analyzing news articles, NER can help you identify and categorize entities like people, organizations, and locations mentioned in the articles, allowing you to track trends or sentiments related to those entities.

  • Word Embeddings:

Word embeddings capture the contextual meaning of words. Suppose you’re building a recommendation system for an e-commerce platform. Word embeddings can help you understand the similarities between product descriptions and user queries, leading to more accurate product recommendations.

  • Word2Vec:

Word2Vec is all about understanding the context in which words are used. Let’s say you’re building a search engine. Word2Vec can help you understand the relationships between search terms and relevant documents, improving the accuracy of search results.

  • Bag of Words (BoW):

BoW is a simple yet powerful technique for text analysis. If you’re analyzing customer feedback for a product, BoW can help you identify common themes or topics mentioned across different feedbacks, helping you prioritize areas for improvement.

  • TF-IDF (Term Frequency-Inverse Document Frequency):

TF-IDF helps us understand the importance of words in a document. For instance, if you’re analyzing resumes for a job opening, TF-IDF can help you identify keywords that are highly relevant to the job description, making it easier to shortlist candidates.

  • Language Models:

Language models are the backbone of many NLP applications. Whether it’s generating text, translating languages, or transcribing speech, language models play a crucial role in understanding and generating human language.

Step-by-step guide to experimenting with LLMs


ChatGPT :


Step 1: Setting Up Your Environment


Before diving into experimenting with ChatGPT, you’ll need to set up your environment. First, ensure you have Python installed on your system. Then, install the OpenAI Python library using pip:

					pip install openai 

Step 2: Obtaining Your API Key :

To interact with ChatGPT, you’ll need an API key from OpenAI. You can obtain your API key by signing up on the OpenAI website ( Once you have your API key, store it securely.

Step 3: Import Libraries

Import the necessary libraries in your Python script, specifically the OpenAI library.

					import openai 

Step 4: Authenticate

Set up authentication by providing your API key to OpenAI 

					openai.api_key = 'your-api-key' 

Step 5: Experimenting with GPT by writing professional emails

					context = [] 
user_input = input("Enter the context or outline of your email: ") 
context.append({"role": "system", "content": "You are a bot that helps to write professional emails."}) 
context.append({"role": "user", "content": user_input}) 
response = openai.ChatCompletion.create( 

print("\nHere's your completed email:") 


Step 1: Get the API key

					HUGGINGCHAT_API_KEY = "your_huggingchat_api_key" 

Step 2: Authenticating with the HuggingChat API

Now that our configuration is complete, let’s write some code to authenticate ourselves with the HuggingChat API. In a new Python script, add the following imports and initialization code:

					import os 
import requests 
from dotenv import load_dotenv 

HUGGINGCHAT_API_KEY = "your_huggingchat_api_key" 
    'Authorization': f'Bearer {HUGGINGCHAT_API_KEY}', 


Step 3: Sending Requests to the API

With our authentication ready, we can now send requests to the HuggingChat API. Let’s define a function called send_request which accepts two parameters – the model name and input prompt. It sends a request to the API and returns the response as JSON data.

					def send_request(model: str, prompt: str):
    url = f'{model}' 
    payload = {'inputs': prompt} 
    response =, json=payload, headers=HEADERS) 
    if response.status_code != 200: 
        print('Error while sending request!') 
        return None 
    result = response.json()[0]['generated_text'] 
    return result 

Step 4: Examples of Usage

					def main(): 
    question = "Who discovered electricity?" 
    model = "t5-base" 
    prompt = f">>> {question}\nAnswer:" 
    response = send_request(model, prompt) 
    print(f">>> {response}")
