How Does ChatGPT Work In Simple Terms?

How does ChatGPT work and what do people use ChatGPT for? These are common questions most people ask especially those who are in dire need of how a chatbot works.

ChatGPT is a conversational AI chatbot created by OpenAI, a research organization dedicated to creating and promoting beneficial artificial intelligence. ChatGPT can answer questions, generate text, write code, summarize information, translate languages, and much more, depending on the prompt you give it. You can think of ChatGPT as a very smart and versatile assistant that can help you with various tasks or just have a friendly chat with you.

ChatGPT is important and interesting because it demonstrates the power and potential of generative AI, which is a type of AI that can create new content from scratch, rather than just analyzing or processing existing data. Generative AI can enable new forms of creativity, innovation, education, entertainment, and communication. However, generative AI also poses some challenges and limitations, such as ensuring its accuracy, reliability, safety, ethics, and social impact.

Whether you seek answers for; how does ChatGPT generate responses, how does ChatGPT get its information, or anything in between, you will definitely find this guide helpful.

How ChatGPT Works

ChatGPT is based on OpenAI’s Generative Pre-trained Transformer 3 (GPT-3), which is one of the largest and most advanced language models in the world. A language model is a computer program that learns how to use natural language (such as English) by analyzing a large amount of text data (such as books, articles, websites, etc.). A language model can then generate new text based on what it has learned.

GPT-3 is trained on billions of words from the internet, covering a wide range of topics and domains. It uses a deep neural network, which is a complex mathematical system that mimics how the human brain works, to learn the patterns and rules of language. GPT-3 can generate text for any given input or prompt by predicting the most likely words or sentences to follow.

ChatGPT uses GPT-3 as its foundation but adds some additional features and modifications to make it more suitable for conversational AI. For example, ChatGPT uses a dialogue format, which means that it can interact with human users in a back-and-forth manner. It can also answer follow-up questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests.

ChatGPT also uses reinforcement learning from human feedback (RLHF), which means that it can learn from its own experience and improve over time. RLHF involves collecting data from real conversations between human users and ChatGPT and then using a reward model to evaluate the quality of ChatGPT’s responses. The reward model is based on human ratings or preferences of different responses. Using this feedback, ChatGPT can adjust its parameters to generate better responses in the future.

How to use ChatGPT

There are different ways to access and interact with ChatGPT. The simplest way is to use the web-based interface at There you can type in any prompt or question you want, choose from different modes (such as balanced, creative, or precise), and see how ChatGPT responds. You can also browse through some examples of prompts and responses for various use cases.

Another way to use ChatGPT is to prompt engineering without APIs. This means that you can use other technologies or tools (such as screen scraping or robotic process automation) to create workflows that involve ChatGPT. You can use an email client to send prompts to ChatGPT via email, and then receive responses via email as well.

A third way to use ChatGPT is to prompt engineering using APIs. This means that you can use programming languages or frameworks to set and evaluate prompts programmatically and directly integrate ChatGPT with a broad range of applications. For example, you can use Python or JavaScript to create a web app or a chatbot that uses ChatGPT as its backend.

A fourth way to use ChatGPT is to custom-build or direct interaction with a foundation model. This means that you can leverage your own version of GPT-2/GPT-3 or other foundation models for a bespoke implementation. However, you would not be using the customized version of GPT-3 or GPT-4, which users cannot change.

How To Use Chatgpt Effectively And Responsibly

Some tips and best practices for using ChatGPT effectively and responsibly are:

  • Be clear and specific with your prompts. ChatGPT works best when the prompts are well-formed and unambiguous. Avoid vague or open-ended prompts that may confuse ChatGPT or lead to irrelevant or inappropriate responses.
  • Be aware of the limitations and risks of use. ChatGPT is not perfect and may sometimes produce misleading, inaccurate, or untruthful answers. It may also generate offensive or harmful content that may violate ethical or legal norms. Always verify the information and quality of ChatGPT’s responses before using them for any purpose.
  • Be respectful and polite with the chatbot. ChatGPT is designed to be friendly and helpful, but it is not a human being. It does not have feelings, emotions, opinions, or preferences. Do not abuse, insult, harass, or exploit ChatGPT in any way. Treat ChatGPT as a tool, not as a person.

What is the difference between ChatGPT and InstructGPT?

ChatGPT is a sibling model to InstructGPT which is trained to follow an instruction in a prompt and provide a detailed response. The main difference is that ChatGPT uses a dialogue format while InstructGPT uses an instruction format.

Is ChatGPT free to use?

Currently yes but only during the research preview period which may end soon. OpenAI has not yet announced the pricing or availability of ChatGPT after the research preview period.

How can I change the mode of ChatGPT?

You can use the toggle button on the web interface to switch between balanced, creative, and precise modes. Each mode has a different level of creativity and accuracy.

How can I chat with ChatGPT in another language?

Use the language option on the web interface to select from a list of supported languages. ChatGPT will try to detect and match your language automatically.


ChatGPT is an amazing example of generative AI that can interact with human users in a conversational way. It can answer questions, generate text, write code, summarize information, translate languages, and much more. However, ChatGPT also has some challenges and limitations that users should be aware of and cautious about.

ChatGPT is still in development and research stage by OpenAI. It is not yet widely available or accessible to the public. However, OpenAI plans to make ChatGPT more accessible and useful in the future by improving its performance, reliability, safety, ethics, and social impact.

ChatGPT is not only an impressive technology but also an exciting opportunity for learning, creativity, innovation, communication, and entertainment. It opens up new possibilities and challenges for human-AI interaction and collaboration.
