ChatGPT is a long-form question-answering AI from OpenAI that responds to complicated questions. It's an exciting new technology that is being taught to understand and respond to questions posed by people IRL.

Its capacity for human-like response has sent shocks to the whole world, giving rise to the notion that it could one day transform how people interact with computers and how information is found.

What is ChatGPT (Chat Generative Pre-trained Transformer)

OpenAI launched ChatGPT in November 2022, a chatbot with a large language model. As a result, you can communicate with a chatbot in various ways. The language model can help you with coding, email creation, and essay writing, as well as answer your inquiries. Both reinforcement learning and supervised learning approaches are used to fine-tune ChatGPT.

ChatGPT was trained by gathering significant data with an October 2021 cutoff. Then, using additional datasets with human-labeled labels, the model is continuously evaluated and improved for various language-oriented tasks. It’s fascinating to see how it can engage in conversation and respond with comments that sometimes seem quite insightful.

Technically speaking, ChatGPT falls within the category of generative AI. Once trained, a generative AI model can generate results similar to the training data but not precisely the same.

3) Writing test cases

ChatGPT can help developers to write test cases in a variety of ways. One way is by recognizing the test case's purpose and creating test inputs and expected outcomes. For example, suppose a developer asks ChatGPT to write a test case that can handle invalid input. In that case, ChatGPT may generate invalid inputs, such as special characters, empty strings, and out-of-range values.

ChatGPT is helpful in writing test cases because of its ability to identify the logic and the structure behind the code you provide. Because of that, ChatGPT can write test cases covering different code paths and edge cases. For example, suppose a developer provides a code snippet and tells ChatGPT that the code should be able to handle big data sets. In that case, it can produce test inputs with big data sets. 

ChatGPT can also be used to generate test case documentation. It can generate short, easily understandable descriptions of the test cases, including the test inputs, predicted outcomes, and conditions under which the test cases should pass or fail. As a result, developers, even those who don't have any testing knowledge, can quickly update the given test cases.

Below, you can find my ChatGPT result after asking to generate a test case for above mentioned "getHttpMethod" wrapper function.

If we break down ChatGPT's result, we can see that ChatGPT has used Jest and that the generated test case includes two tests. The response of the GET request compares with the expected output and checks whether the function works as expected.

4) Simplifying codes and explaining complex code snippets

With ChatGPT, programmers can quickly produce plain language explanations of complicated code sections, making it simpler for others to comprehend and maintain the code. 

By automatically generating code comments and documentation, ChatGPT can be used to simplify the code. Developers can therefore save a considerable amount of time and effort. In addition, due to the model's ability to comprehend the underlying logic and structure of the code, ChatGPT's generated documentation and comments are frequently more accurate and informative than a developer might write.

By assisting programmers in code refactoring and optimization, ChatGPT may also aid developers in making their code simpler. For example, the model may evaluate the code and make suggestions for enhancements, such as trimming down the code's lines or boosting efficiency. This can improve performance, make the code more readable and manageable, and result in fewer bugs.

Can You Trust ChatGPT?

ChatGPT is sometimes incorrect. It struggles with basic math, sometimes it's unable to understand simple logic, and will even present facts entirely false in its justification. This issue is acknowledged by OpenAI, which states that 'ChatGPT sometimes writes plausible-sounding but incorrect or nonsensical answers'.

ChatGPT makes a series of guesses before coming up with a response, so it may justify incorrect answers as if they were correct.

Additionally, ChatGPT was educated on people's historical and current collective writing worldwide. This implies that the ChatGPT's responses may have the same biases seen in the data. Therefore, when asking Chat GPT important questions, you must remember its biased behavior.

It's an effective learning tool that does a wonderful job of presenting complex subjects. However, it would be best if you don't take everything it says at face value.

Next step: ChatGPT 4.0

The next phase of ChatGPT is ChatGPT 4. It will be more intelligent, have more features, and contain a variety of skills that ChatGPT currently doesn't have.

The current version of ChatGPT, accessible to the general public, can access 175 billion parameters to comprehend questions and respond accordingly. With over 175 billion parameters, ChatGPT can generate everything from coding, WordPress apps, essays, poems, and even music. Though there are many things to take into account here, like whether AI has the right to copy someone else's property.

The number of parameters available in ChatGPT 4 will exceed 100 trillion. Its capacity for learning and its possible applications will both experience a massive rise as a result. We're talking about a quantum leap here.


ChatGPT is a valuable resource for developers looking to save time and effort in their work. Its ability to generate code snippets, answer questions, and create documents in a few seconds can definitely improve productivity. However, it's important to remember that its responses are not always 100% accurate, so you need to do thorough research before using it for more advanced tasks.
