Before we begin, here is a quick look at what GitHub Copilot is.

What is GitHub Copilot?

GitHub Copilot was developed by teams from both GitHub and OpenAI, as an “AI pair programmer.” The AI tool helps you autocomplete code and makes programming more efficient. It turns natural language prompts into coding suggestions based on the project’s context and style.

To put it simply, GitHub copilot is like a search engine, but one that is exclusively for use by programmers. When you ask Google “How to …”, Google gives you a bunch of suggestions based on articles various people have written. GitHub copilot does something similar, albeit with code and using artificial intelligence.

GitHub Copilot is designed to seamlessly integrate with Visual Studio Code, providing developers with real-time suggestions as they type in code. Copilot scans your code, gets the context, and suggests functions, relevant snippets, and even entire blocks of code in real-time.

GitHub Copilot Features

GitHub Copilot is not just like any other “coding assistant” out there. Having been trained on a vast amount of code from GitHub and with ChatGPT 4 powering it, GitHub Copilot comes with an impressive list of features. Some of the GitHub Copilot features include:

1. Helps in learning a new programming language: If you are learning a new programming language, say Python, then CoPilot can help in your learning journey, by giving you examples and templates. Copilot acts as a learning companion, giving you instant examples and guidance.

2. Rapid coding sessions: Copilot helps speed up the process of coding by not only completing separate functions but also taking care of the edge cases. This saves time and ensures there is precision. Copilot’s ability to generate entire lines or blocks of code comes in handy for tasks where speed is crucial.

3. API integration: When you want to integrate a new API into your project, Copilot can generate the initial code structure, with authentication, request handling, and response parsing, based on your API documentation.

4. Test Case Generation and Complex Data Structures: If you need to work with complex data structures like graphs or trees, Copilot can give you ready-made code snippets for creating, manipulating, or traversing intricate data structures. This will save you from implementation errors. If you wish to create a suite of test cases for a complex function, Copilot can assist in generating diverse test cases, covering different test scenarios.

5. Dynamic UI components and integration with the Cloud: When you are building dynamic User Interface components with Javascript, Copilot can create code for interactive UI elements, handle user input, and manage state. This allows you to focus on specific functionalities of your component. Copilot can also help you integrate your application with cloud services like AWS or Azure, by setting up authentication and making API calls.

GitHub Copilot Limitations

While the list of Copilot’s features is impressive, there are a few limitations with this AI tool, since it is still under development. Let us look at these GitHub Copilot limitations:

1. It can be distracting: GitHub Copilot suggests many different things, which can be distracting for a few people. This loss in concentration for the developers may lead to the slowing down of the entire coding process.

2. Licensing issues: When a programmer writes code using GitHub Copilot, it can become the property of Microsoft. This will become problematic to coders who want ownership of their code.

3. Bloated code: Some of the code generated by Copilot is longer than necessary. This will lead to bloated code, making it unnecessarily complex for developers. Developers will then need to refactor and review the generated code, to make sure it aligns with the project guidelines.

4. Heavily dependent on training data: Copilot has been trained on a massive set of code, and some of this code may be suboptimal. If such training data is not the most efficient or is dated, then Copilot may continue generating such code, leading to the amplification of errors.

GitHub Copilot Pricing

• Copilot is currently priced at $10/month if billed monthly.
• If billed annually, this price is reduced to $100/year.

What is ChatGPT

ChatGPT is an AI tool that is based on a Large Language model developed by OpenAI. It took the internet by storm when it was introduced in November of 2022, and became the fastest-growing internet application in history.

At its heart, ChatGPT is a chatbot, and users generally ask it questions in the form of prompts. ChatGPT constantly learns from user inputs and is not just a coding companion like GitHub Copilot. ChatGPT can be used to write emails, essays, blog posts, and poems, summarize texts, and a wide variety of use cases.

So when do you use ChatGPT over GitHub Copilot? Let’s take a look.

ChatGPT Features

ChatGPT is a tool that is still under development, but certain features are extremely helpful to developers. Let us take a look at a few of ChatGPT’s features.

1. Helps to understand underlying concepts: When you have a programming concept that is perplexing or abstract, then ChatGPT can break it down for you and explain it with simple analogies that make the program more accessible. For instance, if you need to understand recursion, ChatGPT will explain it to you using an everyday example, like a Russian nesting doll. Understanding what your code does is very important in finding and fixing bugs, and ChatGPT can help you.

2. Explore Alternative Approaches: With ChatGPT, you can have dynamic conversations, and it allows you to explore various options to solve the same problem. For instance, if you are designing a feature that has real-time updates, CoPilot can aid you just in implementation. On the other hand, ChatGPT can discuss the trade-offs between using Websockets and HTTP polling. You get a better hang of things like latency, ease of implementation, and scalability.

3. Help in troubleshooting: When you encounter a bug in your existing code and need help troubleshooting it, ChatGPT can help in diagnosing issues. It does so by engaging in a conversation with you about the underlying code, potential causes for the bug, and how you have to debug it. For example, if your web app is not rendering images correctly, ChatGPT can give you actual steps to follow to fix this issue, like checking the image file paths and ensuring proper server configurations.

4. Choosing the Right Data Structures: Choosing the right data structure is a massive undertaking, especially if you are designing a very data-intensive application. ChatGPT in this case can help you explore the actual requirements of your application, discussing with you the data structure choices and helping you make informed decisions.

5. Generating Pseudocode: ChatGPT can help you craft a pseudocode, giving you a high-level representation of your algorithm. This will help you iron out any issues that might arise before implementation. ChatGPT will help you structure the steps and clarify the algorithm’s logic before actually converting it into code.

ChatGPT Limitations

While we have seen that ChatGPT can serve as an impressive coding assistant, there are a few drawbacks here too, which can be off-putting for some. Here are ChatGPT’s limitations:

1. It doesn’t compile code: ChatGPT can give you snippets of code, along with explanations, but it doesn’t interact with a compiler or interpreter to validate if the code is correct. This means developers must independently test and execute the code generated by ChatGPT in a suitable compiler to see if the code is working.
2. Inability to understand context: ChatGPT may not be able to understand the broader context of the code and interpret code on a line-by-line basis. Thus, it will struggle with complex instructions which require a more comprehensive understanding of the codebase.
3. Limited recent knowledge: The main objective of ChatGPT is text completion, and the free version, ChatGPT 3.5, is based on a vast dataset that goes up to only June 2021. Thus, when you ask ChatGPT for help to build an app, it will refer to similar code, which is most likely outdated. The library definitions and features will also be older, meaning that if there is any feature update after that, the language model will be unaware of it.
4. Hallucinations: When you give a prompt that is not specific enough, it may make a shortcut and return a code that has undefined functions. While this may solve part of the problem, developers may not be able to get the full details of these functions, leading to ambiguities in the code.

ChatGPT Pricing

• Free: $0/month
• Plus: $20/month
• Team: $25 per person/month*
