GitHub Copilot vs. ChatGPT: Which Is Better for Programming?

Jayric is a Forensic Science graduate with over five years of writing experience and a passion for reverse engineering and hardware.

 

His tech journey kicked off in childhood with an old hand-me-down Nokia N91, where he repackaged Java games like a Symbian port of Pokémon Blue to tweak TMs and Poké Dollars. By high school, he was flashing custom Android ROMs and trading modded games for lunch money, and in college, he learned C/C++ and electronics on a TI Tiva C LaunchPad, then went on to create DIY projects ranging from USB security keys to home automation devices.

 

Jayric now enjoys writing at MUO to keep sharing and learning about tech while honing his own craft. Outside of tech, he enjoys grinding CS2 and Dragon Nest, lifting weights, running daily 5Ks, and reading in his greenhouse.

GitHub Copilot and ChatGPT are two of the most popular AI programming aids available. They use the same GPT large language model and are capable of generating, suggesting, and checking code.

So, which one should you be using?

GitHub Copilot is an AI-powered code completion tool developed by GitHub in collaboration with OpenAI. With the power of GPT-4, it provides real-time code suggestions as you type, helping to streamline the coding process. It is a paid service that you can easily use with most popular environments, including Visual Studio, Visual Studio Code, Vim/Neovim, Azure Data Studio, and JetBrains.

ChatGPT is OpenAI's chat-optimized AI chatbot. While not specifically designed for programming assistance like GitHub Copilot, ChatGPT’s strength lies in its ability to comprehend and generate text in a manner that closely mimics human language.

This makes it a good programming tool as it can help clarify concepts, provide explanations, and even generate pseudocode based on user input. ChatGPT is a versatile tool. You can use it for non-coding tasks like planning, brainstorming, and problem-solving, all of which are useful in software development.

The main reason to use GitHub Copilot for programming is its advanced code suggestions. By fine-tuning GPT-4 with a vast repository of code from open-source projects, and further customizing suggestions based on what you’re currently working on, GitHub Copilot provides code suggestions that fit your project.

GitHub Copilot can save you a lot of typing by providing contextually correct suggestions:

Aside from advanced code completion, you can also use GitHub Copilot for refactoring, helping you write cleaner and better code. And since it’s integrated into your programming environment, it’s more quickly available than a web app like ChatGPT. This saves you time and concentration, especially over long coding sessions.

To make a request, simply highlight your code, click on the “twinkle/star” icon, and provide your instructions:

Your subscription to GitHub Copilot also comes bundled with GitHub Copilot Chat. You can use it to ask coding questions, debug your program, and generate new lines of code. GitHub Copilot Chat generates usable code that will be a good fit for your project:

If your primary focus is on programming, and you're looking for a tool to help you with writing, debugging, and refactoring code, GitHub Copilot is the clear choice. Its ability to generate accurate and contextually relevant code snippets can significantly speed up development workflows and reduce coding errors.

Furthermore, its integration with popular IDEs, multi-language support, and collaborative coding system ensures GitHub Copilot works well on any team-based project. Whether you're programming for a passion project or a team player in a large company, GitHub Copilot provides advanced AI capabilities that make coding fast and easy.

While ChatGPT may not match GitHub Copilot's prowess in code completion, it excels in other aspects outside of programming. It can be an invaluable tool for designing and brainstorming your project.

If you’re learning to code, you can prompt ChatGPT to generate pseudocode to help you explore different solutions for a specific problem.

Here’s how ChatGPT provided a way to query the minimum, maximum, and average price of products within a collection class:

If you’re looking at a snippet of code you don’t quite understand, you can also use ChatGPT to reverse engineer it:

When it comes to understanding concepts or getting a detailed explanation of a coding topic, ChatGPT excels. Its ability to generate human-like responses makes it an ideal learning tool that any programmer can use. Whether it's a complex algorithm or a programming principle you're trying to grasp, ChatGPT can break it down into understandable parts.

What’s great about ChatGPT is that it offers a completely free version that you can use throughout your learning process. Of course, a paid subscription does have extra benefits like better response quality and plugins. But overall, as long as you employ prompting techniques, the free version should work fine as a learning tool.

Why choose between GitHub Copilot and ChatGPT when you can use both to your benefit? Integrating these tools into your workflow can offer the best of both worlds.

Use GitHub Copilot for code completion and ChatGPT to understand concepts and reinforce learning. Both together should provide enough help for you to program a well-thought-out project you’ll be happy to show off.

If you’re a student, you can benefit from free access to GitHub Copilot. Combine that with OpenAI’s already free ChatGPT-3.5 Turbo, and you’ll have both tools without paying a cent!

A monthly GitHub Copilot subscription and the freely available ChatGPT-3.5 should provide enough assistance for both personal and professional projects. If you still feel like you need that slight edge, then shelling out extra for useful ChatGPT plugins may also be worth the investment.

Though GitHub Copilot and ChatGPT have become the most popular AI tools used in software development, there are also alternatives worth exploring. For code completion and generation, tools like TabNine and Codeium offer similar functionality to GitHub Copilot.

Aside from Claude AI, there are no really good alternatives to ChatGPT unless you want to spend time setting up a local chatbot. In that case, you may be interested in chatbots like GPT4All, Nvidia Chat with RTX, and the various BERT models using TextGen WebUI.
