What is ChatGPT?

ChatGPT is an AI chatbot that is powered by OpenAI’s GPT (Generative Pre-trained Transformer) technology. It is a natural language processing tool that allows users to have human-like conversations with the chatbot. As of September 2023, ChatGPT-3.5 is the latest version of the tool.

Origins of ChatGPT

ChatGPT was developed by OpenAI, an artificial intelligence research laboratory consisting of the for-profit corporation OpenAI LP and its parent company, the non-profit OpenAI Inc. OpenAI was founded in 2015 by a group of technology leaders, including Elon Musk and Sam Altman, with the goal of developing safe AI technology that benefits humanity.

ChatGPT is built on a family of large language models (LLMs) collectively known as GPT-3. GPT-3 is a deep-learning-based language model that uses unsupervised learning to generate human-like text. It was released in June 2020 and quickly gained popularity due to its impressive language generation capabilities.

Functionality of ChatGPT

ChatGPT can be used for a variety of purposes, including customer service, language translation, and personal assistance. It can answer questions, provide recommendations, and even engage in small talk. ChatGPT can also be customized to fit specific use cases, such as providing medical advice or financial planning.

ChatGPT is trained on a massive amount of data, which allows it to generate responses that are contextually relevant and grammatically correct. It can also understand and respond to natural language inputs, which makes it easier for users to communicate with the chatbot.

Language Used in Coding ChatGPT

We have researched and found that ChatGPT is coded in Python, a popular high-level programming language. Python is known for its simplicity, readability, and ease of use. It is widely used in various fields such as web development, data science, machine learning, and artificial intelligence.


Python is an interpreted language, which means that it does not need to be compiled before it is run. This makes it easy to write and test code quickly. Python also has a large standard library, which provides a wide range of tools and modules for different tasks. This makes it easy to develop complex applications without having to write a lot of code from scratch.


PyTorch is an open-source machine learning library that is used extensively in ChatGPT. It is developed by Facebook’s AI research team and is built on top of Python. PyTorch provides a flexible and efficient platform for building and training machine learning models. It also has a dynamic computation graph, which makes it easy to debug and optimize models.


TensorFlow is another open-source machine learning library that is used in ChatGPT. It is developed by Google and is widely used in various fields such as computer vision, natural language processing, and speech recognition. TensorFlow provides a high-level API for building and training machine learning models. It also has a large community of developers who contribute to its development and provide support to users.

How ChatGPT Works

ChatGPT is an AI chatbot that uses a combination of machine learning, natural language processing, and transformers architecture to generate human-like responses to text-based prompts.

Machine Learning

At its core, ChatGPT is a machine learning system that is trained on a massive corpus of text data. The system is built on top of the GPT (Generative Pre-trained Transformer) architecture, which is a type of neural network that is specifically designed for natural language processing tasks.

During the training process, the system is exposed to a wide range of text-based inputs and corresponding outputs. This allows the system to learn patterns and relationships within the data, which it can then use to generate new responses to similar inputs.

Natural Language Processing

In order to generate human-like responses, ChatGPT relies heavily on natural language processing (NLP) techniques. NLP is a field of study that focuses on the interaction between computers and human language.

ChatGPT uses a variety of NLP techniques, including tokenization, part-of-speech tagging, and named entity recognition. These techniques allow the system to understand the structure and meaning of the input text, which it can then use to generate more accurate and relevant responses.

Transformers Architecture

The transformers architecture is a key component of ChatGPT’s ability to generate high-quality responses. This architecture is designed to process sequences of input data, such as natural language text.

The transformers architecture is composed of multiple layers of neural networks, each of which is responsible for processing a different aspect of the input data. This allows the system to capture complex relationships between words and phrases, which it can then use to generate more sophisticated responses.


What programming language is ChatGPT built with?

ChatGPT is built using Python, a popular high-level programming language known for its simplicity and readability. Python is widely used in the development of AI and machine learning applications, making it a natural choice for ChatGPT’s development.

Is ChatGPT coded in Python?

Yes, ChatGPT is coded in Python. The codebase is built on top of the PyTorch framework, a popular deep learning library for Python. The use of Python and PyTorch allows ChatGPT to efficiently process large amounts of text data and generate human-like responses to prompts.

What algorithms are used in ChatGPT’s code?

ChatGPT uses a combination of deep learning algorithms, including transformer models and neural networks. The transformer model is a type of neural network architecture that is particularly well-suited for natural language processing tasks like text generation. In addition, ChatGPT uses unsupervised learning techniques to improve its performance over time.

What is the size of ChatGPT’s codebase?

The exact size of ChatGPT’s codebase is not publicly available, but it is known to be quite large. The model was trained on a massive dataset of text, which required a significant amount of computing power and storage space. However, the size of the codebase is not necessarily indicative of the model’s performance or accuracy.

Can ChatGPT generate code for apps?

No, ChatGPT is not designed to generate code for apps or other software applications. Its primary function is to generate human-like responses to text prompts, making it useful for a wide range of natural language processing tasks. However, there are other AI tools and platforms available that are specifically designed for code generation.

What are some alternatives to using ChatGPT for coding?

There are several alternatives to using ChatGPT for coding, depending on the specific task at hand. Some popular options include using traditional programming languages like Java or C++, using code generation tools like CodeSmith or CodeRush, or using other AI-powered code generation platforms like Kite or TabNine. Ultimately, the choice of tool will depend on the specific requirements of the project and the preferences of the developer.


ChatGPT is a generative AI model that is used to create chatbots. It is not coded in any specific language, but rather is trained on large datasets to generate new data such as text, images, or audio. ChatGPT is unique in that it is able to generate human-like responses to user input, making it a powerful tool for creating conversational interfaces.

While ChatGPT is not coded in any specific language, it is built on top of existing AI models and frameworks such as GPT-2 and PyTorch. These models and frameworks provide the underlying architecture and algorithms that allow ChatGPT to generate responses to user input.

One of the key advantages of ChatGPT is its ability to learn from large datasets of human conversation. This allows it to generate responses that are more natural and human-like than traditional chatbots. Additionally, ChatGPT can be customized to specific domains or use cases, allowing it to provide more targeted and relevant responses to users.
