How Does ChatGPT Work? Get the Most Out of ChatGPT!

Let’s take a few steps back to remember the pre-ChatGPT era. 

  • Writing and coding everything from scratch 
  • Spending hours on research 
  • Difficulty understanding an extremely complicated journal paper on niche subjects 
  • Reading a 50-pager document to write a 10-sentence summary 

Certainly not the best use of time, especially when juggling multiple tasks. 

Thanks to ChatGPT, whether you’re writing a summary of other documents or creating a blog post from scratch—you get a human-like copy within seconds. 

  • But how does ChatGPT work? 
  • What technology does it use? 

Whether you are an AI enthusiast trying to learn about ChatGPT language modeling, a developer looking to leverage natural language processing, or a business user searching for a ChatGPT alternative, we answer all your queries in this article. 

What is ChatGPT? 

ChatGPT, aka Chat Generative Pre-trained Transformer, is an AI tool developed by OpenAI, a Microsoft-backed AI research company. 

ChatGPT, launched in November 2022, is an intelligent chatbot that remembers past conversations, mimics those conversations, generates appropriate responses and new ideas, and elaborates on existing ideas. 

Check the image below for an example. 

ChatGPT's answer to user queries

We asked ChatGPT to share three podcast episode ideas related to SaaS content marketing. It provides content ideas along with a rough plan for structuring each episode. 

ChatGPT uses GPT language models to help you with real-life solutions and complex use cases like: 

  • Responding to a complicated question whose answer is not readily available in search engines, and you don’t need to compile scattered information from multiple websites to compile this data 
  • Brainstorming with you to generate content ideas on a particular topic (like we did above)
  • Summarizing data from various sources (think: journals, websites, news articles) to simplify your research process 
  • Write content and copies for your articles, landing pages, social media posts, emails, and video scripts 
  • Translate code from one programming language to another 

ChatGPT currently has two models: ChatGPT 3.5 is the Beta version available for free and ChatGPT 4 is the premium version, which costs $20 per month. 

Understanding the Technology Behind ChatGPT 

OpenAI released the first three models of the GPT series, namely GPT 1,2 and 3, in 2018, 2019, and 2020, respectively. While GPT 1 contained only 117 million parameters, GPT 3 was a far more advanced version with 175 billion parameters, capable of providing human-level responses for various tasks. 

All these GPT models are built with Large Language Model [LLM] technology and neural networks. 

LLM is trained on a large volume of data like any other artificial intelligence-based system [think of virtual assistants Alexa and Siri—who recognize your voice, remember your birthday, and notify you about your meetings]. 

The Large Language Model processes all training data (more on training in the next section) through neural networks (a computer program that imitates the structure of the human brain) and deep learning for data collection. ChatGPT uses a sophisticated neural network known as a transformer and pre-training. 

Transformer architecture 

OpenAI’s complex transformer architecture reads massive volumes of texts, identifies patterns on how texts and phrases are interrelated, and predicts the next word. ChatGPT is good at predictive text to generate responses that resemble human knowledge. 

However, for the same question, ChatGPT’s AI models give personalized responses that are somewhat similar but not identical.

There’s some randomness in the written code to enable auto-correct capabilities. Soon, LLM models will give tough competition to super-charged autocorrect engines because they can process vast amounts of data based on millions of user queries for a specific task. 

Pre-training 

Pre-training involves two approaches: non-supervised and supervised. 

In the supervised approach, the overall model is trained to learn mapping functions to map inputs to outputs directly. Supervised learning is used for classification, regression, and sequence labeling tasks. 

On the other hand, in the unsupervised learning approach, the AI model is trained on data where no specific output is related to each input. Instead, the model learns the underlying structure and patterns in input data without specific tasks. 

Clustering, anomaly detection, and dimensionality reduction use this training method. 

Regarding language modeling, non-supervised pre-training is used to train the model to understand the syntax and semantics of natural language. This way, it can generate coherent and meaningful text in a conversation context. 

As it is impossible to anticipate all questions that a user would ask, there’s no way ChatGPT could’ve been trained with a supervised learning model. Instead, it uses non-supervised pre-training to make ChatGPT’s limitless knowledge possible. 

In the next section, we cover how ChatGPT works, how OpenAI trains AI models on masked language modeling, next token prediction, and datasets OpenAI uses to train ChatGPT to generate coherent text. 

How Does ChatGPT Work? 

Elementally, ChatGPT cannot differentiate between ‘right’ or ‘wrong.’ ChatGPT looks for feasible, coherent, and closest to its training and human feedback data whenever you enter user queries. 

OpenAI used four datasets to train ChatGPT: 

  • Crawl data: A compilation of text data collected from the internet. While the crawl data included billions of web pages, OpenAI filtered these datasets and demonstration data further to shortlist only reliable web pages as ChatGPT’s training database
  • Wikipedia: The entire database of Wikipedia was used to train and fine-tune ChatGPT
  • Personal chat: OpenAI’s database contains millions of chat datasets
  • WebText2: OpenAI also crawled online communities like Reddit and linked websites mentioned in Reddit threads to build this database called WebText2

Now, let’s deep dive into the training process, which comprises two steps: Tokenization and training the model through the Reinforcement Learning approach. 

Tokenization 

Before the training data passes through neural networks, there is another process called Tokenization, where large chunks of datasets are broken down into bite-sized data or tokens.

The tokenization process helps LLM models analyze data faster. 

Developing Neural Networks 

Once the tokens are broken into characters and assigned to an integer, OpenAI’s transformer processes these datasets into meaningful text. 

Before the training process officially kickstarts, there is a brief phase called ‘Pre-training.’ In this phase, the neural network identifies the relationship between the tokens and predicts the missing words and phrases. 

For example, ChatGPT may learn that in human language, ‘have’ is always used with ‘they,’ and ‘has’ is always used with ‘he’ and ‘she.’ ChatGPT records and stores these parameters to make predictions more relevant in future scenarios. 

In the final phase, OpenAI used the Reinforcement Learning from Human Feedback (RLHF) approach in machine learning to train both these models.

The Reinforcement Learning from Human Feedback model has three distinct steps: 

Does the above image look technical? Let us break it down for you with simpler interpretations of the machine learning models.

Step 1: Training the Large Language Model with many human conversation datasets. This reinforcement learning-driven training helps ChatGPT models generate human-like responses based on their knowledge base and existing data patterns. 

Step 2: Assigning a human trainer for comparison data. The person compares the GPT responses with human-based responses and ranks them from best to worst for reading comprehension. OpenAI later uses this human feedback data to train the reward model. 

Step 3: Retraining the reward models to fine-tune their responses using Proximal Policy Optimization (PPO), an algorithm to train computers in complex decision-making by capitalizing on human feedback. 

Advantages and Disadvantages of ChatGPT 

“In my lifetime, I’ve seen two demonstrations of technology that struck me as revolutionary. The first time was in 1980 when I was introduced to a graphical user interface. The second big surprise came just last year. We asked ChatGPT a non-scientific question: “What do you say to a father with a sick child?” It wrote a thoughtful answer that was probably better than most of us in the room would have given. The whole experience was stunning. I knew I had just seen the most important advance in technology since the graphical user interface. This inspired me to think about all the things that AI can achieve in the next five to 10 years.”  – Bill Gates wrote about ChatGPT in GatesNotes

ChatGPT is the fastest-growing application of all time. While it took Instagram over two years to reach 100 million users, ChatGPT did that in just two months.  

Here’s how ChatGPT’s language models make your life simpler. 

Advantages 

Saves time 

Are you running low on creativity? ChatGPT will be your brainstorming partner.

Suppose you’re a sales rep emailing prospective customers about new product features. Without ChatGPT, you would have to conduct the whole process of writing the email manually. You would write the email, then ask the marketing team for a fine-tuned copy. This takes time, effort, and resources.

With ChatGPT, you can automate tasks such as writing emails to increase your productivity without depending on other departments for help.

All you need to do is ask ChatGPT to create an email sequence that can be further templatized. You can tweak the underlying structure and model outputs for specific tasks based on your requirements.

There are several free AI prompt templates available to match your use case.

ChatGPT is available for integrations 

With applications like Zapier, connect ChatGPT with all your favorite tools like Microsoft Excel, Discord, Facebook Messenger, ClickUp, Slack, Notion, and Microsoft Teams. 

Project managers, agencies, developers, and B2B professionals must integrate ChatGPT with their workspace to automate routine activities to work faster and develop personalized workflows without switching between applications. 

Keeps evolving daily 

ChatGPT is getting trained with new data as we speak and is evolving daily. The best part is, as a user, you also get a chance to contribute to ChatGPT’s improvement journey. 

Each time ChatGPT shares a response to your question, there are options to upvote or downvote it. This is your way of providing human feedback to ChatGPT on its performance and fine-tuning it so the capabilities of the GPT model improve further. 

However, Large Language Models like ChatGPT still have a long way to go. 

Before you rely too much on this tool, note some of its limitations. 

Disadvantages 

Responses don’t always match the search intent 

ChatGPT reads your questions and generates answers closest to its training data. Unlike a search engine focusing on the user’s intent, natural language processing often fails to match search intent primarily because it has no information about you, your profession, age, location, or other demographics. 

As a result, the content generated using ChatGPT often sounds surface-level. Make sure to perform a quality check and edit the AI-generated copy to match your intent.

Limited capabilities 

ChatGPT 3.5, launched in November 2022, has access to information and events until January 2022. You will still have to rely on search engines for more recent queries. 

Ethical concerns are unavoidable 

ChatGPT is biased toward training data and fails to articulate events and information impartially. This is why you cannot rely on ChatGPT model outputs entirely. 

Many educational institutions have banned students from using this tool as it could affect their learning experience. 

Another grave concern is the security issues of using ChatGPT’s language model to generate responses. Several high-security industries, such as government security and military equipment manufacturing, have banned ChatGPT as they do not want sensitive data about their inner workings added to the Large Language Models.

Similarly, if you use ChatGPT for customer or employee service management, the possibility of providing inaccurate, biased information remains.
