AI has made significant strides in recent years, automating numerous aspects of our lives, from self-driving cars to voice assistants. Among these advancements, OpenAI’s ChatGPT has astounded the global community with its uncanny ability to generate human-like text and code based on natural language prompts. This leads many to wonder if ChatGPT or similar AI tools could soon replace human programmers.
While the prowess of AI like ChatGPT is undeniable, understanding the nuances of its functioning, its potential, and its limitations will give us a clearer perspective on its role in programming. This article explores its capabilities and limitations as a programming assistant, following its evolution from its initial release to the more sophisticated version powered by GPT-4. We’ll compare traditional programming practices with coding through ChatGPT, and address the critical question: Is it a useful tool to enhance productivity, a potential tutor for beginners, or could it render human programmers obsolete?
This is part of a series of articles about ChatGPT alternatives.
ChatGPT is an online AI-based chatbot. It was initially based on generative pretrained transformer 3.5 (GPT-3.5), an AI language model developed by OpenAI. It’s trained on a wide variety of text from the internet. But unlike most AI models, which are trained to perform a specific task, GPT-3.5 is a generalist. It has the power to answer questions, write essays, summarize texts, translate languages, and even generate code in any programming language.
The secret sauce of ChatGPT lies in its architecture. The core architecture of ChatGPT is a deep learning model known as a transformer. This model leverages the power of attention mechanisms, which allows it to focus on different parts of the input when generating each word in its output. This architecture provides the model with a robust ability to understand the context and relevance of words in a sentence.
GPT-3.5 has an astounding 175 billion parameters, which are a bit like synthetic brain cells, each making a tiny contribution to the output. With this massive number of parameters, ChatGPT can generate impressively coherent and contextually rich responses, navigating nuanced conversations and delivering detailed information on a myriad of topics.
OpenAI released GPT-4 in April 2023, and ChatGPT can now be used both with the older GPT-3.5 and the newer GPT-4 model. While there are not many details available about the architecture and number of parameters in GPT-4, it’s a far more capable model. According to OpenAI, it was designed to be “more reliable, creative, and able to handle much more nuanced instructions.” A primary innovation of GPT-4 is that it enables larger prompts, between 8,192 and 32,768 tokens in length. (A token is roughly equivalent to four English language characters.)
Since its launch, a primary use case of ChatGPT has been to generate code. Let’s explore the main steps in the evolution of the service as it pertains to code generation.
ChatGPT showcased its initial capabilities in code generation in version 3.5. Using its underlying language understanding and text generation abilities, it could generate simple code snippets based on textual prompts. For example, if you asked it to write a Python function to calculate the factorial of a number, it could do that.
However, these capabilities were somewhat limited. The generated code was often straightforward and simplistic, and while it could handle basic coding tasks, it struggled with more complex problems. It also often required exact, clear, and explicit instructions to generate the correct code.
ChatGPT’s potential for code generation took a leap forward with the release of version 4. This update introduced more advanced code generation capabilities, allowing the model to handle more complex coding tasks with better precision. It could generate longer and more complex code snippets, and its comprehension of programming concepts improved.
Despite these improvements, ChatGPT-4 is still not perfect. It sometimes generates incorrect or inefficient code and can struggle with ambiguous or poorly defined prompts.
To further enhance the code generation capabilities of ChatGPT, OpenAI introduced a code interpreter plugin. This plugin allows ChatGPT to interpret and analyze existing code, which users can upload as files of any format. This can help it generate more accurate and efficient code and perform other advanced tasks.
The code interpreter plugin works by analyzing the input code and providing context to ChatGPT, allowing it to better understand the task at hand. This can result in more accurate and efficient code generation, but it’s still not perfect. The plugin might struggle with more complex tasks or situations where the context is ambiguous or unclear.
One of the initial drawbacks of using ChatGPT for coding is that it’s not natively integrated with most integrated development environments (IDEs). While it can generate code, programmers will have to copy the code and paste it into their IDEs manually. This lack of direct integration can lead to inefficiencies in the coding process, particularly in complex projects.
Another significant limitation is the issue of code privacy. Given that ChatGPT generates its outputs based on the inputs it receives, there’s a risk that sensitive code could potentially be exposed to third parties. To illustrate the risk, OpenAI has already experienced a data breach where more than 100,000 ChatGPT accounts and their data were stolen by attackers.
While ChatGPT can generate code, the quality and security of that code are not guaranteed. The AI bot is not currently equipped with the ability to test the code it generates for potential bugs, vulnerabilities, or inefficiencies. This limitation puts an additional burden on programmers to thoroughly check and verify the code generated by the AI, negating some of the time-saving benefits of the tool and introducing risks in case programmers do not diligently check output.
In addition, ChatGPT cannot operate in an isolated environment. For example, there’s no way to run it in your on-premises data center or inside a virtual private cloud (VPC). This significantly increases the security risk while working on sensitive, proprietary codebases with ChatGPT.

Finally, while ChatGPT might seem like a great tool for junior programmers, it might not be the best tutor. Given its limitations and inability to provide context, using ChatGPT could potentially lead to adopting bad coding practices. Junior programmers must learn the fundamentals of coding from experienced human mentors who can provide context and guidance before relying on code from tools like ChatGPT.
In traditional programming, the responsibility of checking for errors falls squarely on the programmer. We have to meticulously go through our code, line by line, to ensure there are no syntax errors, logical errors, or runtime errors.
In ChatGPT, error checking is still necessary because the tool is not able to test its code, nor does it understand the full context in which the code will be used. However, it can be more challenging to test the code, because the code was generated by AI and might use logic or structure that is unclear to the human tester. Programmers could also fail to check the output, treating ChatGPT output as reliable, tested code, which can lead to serious consequences.
When it comes to interactivity, ChatGPT has a clear edge. Traditional coding is a solitary process, often involving long hours spent alone in front of a computer. ChatGPT, on the other hand, allows for a more interactive experience. You can communicate with it, ask it questions, and get instant responses. This can make the coding process more engaging and less isolating.
However, there’s a flip side to this interactivity. While ChatGPT can respond to queries, it cannot truly understand or think like a human. It can’t provide the kind of creative problem-solving or unique insights that a human programmer can. So, even though it’s more interactive, it can’t replace the human element in programming.
Completeness, in the context of programming, refers to the ability to create a fully functioning piece of software from start to finish. Traditional programming requires a deep understanding of coding languages, algorithms, data structures, and more. It requires careful planning, rigorous testing, and a lot of time and effort.
ChatGPT’s ability to generate code could potentially simplify this process. It could automate certain tasks, generate boilerplate code, or even write entire parts of an application. However, it’s important to remember that ChatGPT lacks the human ability to understand the bigger picture, to plan for contingencies, or to foresee potential issues. So, while it can contribute to the completeness of a project, it cannot achieve it on its own.
Programming knowledge is a must-have in traditional coding. A programmer needs to understand the syntax and rules of the language they’re using, as well as problem-solving and logical thinking skills.
With ChatGPT, users don’t necessarily have to be skilled programmers. The AI model can generate code based on natural language input, making coding more accessible to nonprogrammers. However, this can be misleading, because without a strong grasp of the programming language, users cannot test and verify the quality and suitability of the code. So in reality, using ChatGPT without sound programming knowledge is not recommended.
AI tools like ChatGPT can certainly aid programmers in their work. They can automate repetitive tasks, generate boilerplate code, and even assist in debugging by suggesting potential solutions. This can save programmers a significant amount of time, allowing them to focus on more complex tasks that require human creativity and intuition.
Furthermore, AI tools like ChatGPT can be used as a learning aid. They can help beginners understand the syntax and structure of code, provide examples, and answer common coding questions. This can make the learning process more efficient and enjoyable, and illustrates how AI can be used to enhance human capabilities, rather than replace them.
But while AI tools like ChatGPT can assist programmers, they have their limitations. Let’s delve into why AI can’t fully replace a programmer’s role.
While AI has made significant strides in understanding and generating human-like text, it still has a long way to go before it can fully replace a human programmer. There are several reasons for this:
While ChatGPT, or any AI tool, is unlikely to replace programmers anytime soon, AI coding assistants are becoming an essential part of the development process.
