![-](https://blog.openreplay.com/images/github-copilot-vs-chatgpt/images/A5RVoB4.gif)

This AI writing tool harnesses the [power of Codex](https://openai.com/blog/openai-codex), a generative pre-trained language model credited to OpenAI. Furthermore, it utilizes context from code and comments and immediately suggests individual lines and entire functions. As an AI programmer, it offers autocomplete-style suggestions as the code.

GitHub could provide suggestions by starting to write the code you want to use or by writing a natural language comment that describes what you want the code to do. Moreover, it analyzes the context of the file you are editing and offers suggestions from within the text editor.

The AI tool is trained in all languages in public repositories. The quality of suggestions you receive for every language depends on the diversity and volume of training data for that language. It's available as an extension in [Visual Studio](https://visualstudio.microsoft.com/), [JetBrains](https://docs.github.com/en/copilot/getting-started-with-github-copilot/getting-started-with-github-copilot-in-a-jetbrains-ide) suite of IDEs, and [Neovim](https://neovim.io/). 

### GitHub Copilot Features

### GitHub Copilot Pros and Cons

Let's start with the pros.
1. Excellent at writing boilerplate code. The boilerplate code could be reused as per need, and this means that it could be copied and pasted in various instances of the same source code, saving time.
2. Fast CDN importing. Simply write the library name and 'cdn' in a comment. Afterward, you can press enter, and Copilot will fetch it.
3. Easy to use. The tool is not overbearingly obnoxious and does not offer suggestions each step of the way.
4. Resolving a problem. GitHub Copilot could create a div at runtime alongside other elements with some data fetched. Furthermore, if you get an error, the tool could solve it for you.
5. Learning capabilities. Copilot could significantly help you learn. It will resolve doubts and problems with well-commented code. 

Cons
1. Flow interruption. The need to review code suggestions could cause a break in flow when working on projects.
2. Difficult to understand code suggestions. There are instances when it would suggest code that you may not understand.
3. Partial error code. Sometimes, GitHub Copilot generates code with partial error. An inexperienced eye may not notice the suggestion error, wasting a lot of time for developers who will detect and correct the error later on.
4. Security and liability concerns. Questions on where code comes from, the license, and copyrights are all valid concerns and questions. These are difficult to answer at present.

## GitHub Copilot vs. ChatGPT—A Comparison
Copilot is more focused on helping developers in the code-writing process, whereas GPT is more of general public use, including developers. Let's start comparing ChatGPT and GitHub Copilot by measuring some important parameters.

### How GitHub Copilot works

The tool uses OpenAI GPT-3, a [language-prediction model](https://openai.com/research/better-language-models) to comprehend the code context and suggest code lines to complete your code. When starting a project, the tool is excellent since it can generate variable names, functions, and algorithms aligned with your programming style.

However, using it in the middle of a project could result in better code suggestions that require a significant amount of rewriting an existing code. As an AI programmer, Copilot could learn from the code you write and, in time, will improve.

### How ChatGPT works

As the name suggests, it's a chat tool wherein you can have a dialog on different subjects. Furthermore, when given prompts, it will generate text that continues the dialog. With ChatGPT, you could ask anything, such as generating unit tests and other things that are related to programming.

Keep in mind that the model is based on events that occurred until 2021. It could not say anything about what occurred before that year. The tool works better if you provide more detailed instructions.

### Code Comparison between Github Copilot and Chat GPT
The main task of GitHub Copilot is completing code and helping developers boost productivity with repetitive, simple code snippets. ChatGPT, on the other hand, is a chatbot framework that can still help developers in the development process.

Copilot helps you better suggest a concrete function implementation, while ChatGPT helps you design big systems and provide a roadmap of how it will be done. For instance, ChatGPT could create a syntax for a new programming language, build context-free grammar, and recommend steps for compiler implementation. On the other hand, Copilot helps you create simple functionalities, such as parseExpression(), by analyzing the structure and overall context of a project. Let's compare them with the same query in Python.
