GitHub Copilot vs ChatGPT

GitHub Copilot and ChatGPT are two of the most popular artificial intelligence writing tools these days. Although both have the power to help write efficiently and provide code snippets, they have different capabilities and are designed for different purposes and intents. This article will dig into their abilities and features, and use both instances to better understand which you should use.

Let’s start with an overview of both tools and then move on to comparing them.

GitHub Copilot — An Overview


This AI writing tool harnesses the power of 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, JetBrains suite of IDEs, and Neovim.

Moreover, ChatGPT is a natural language processing tool that lets you have human-like conversations and a lot more with a chatbot.

The language model of the tool could answer questions and help you with several tasks, which include composing essays, coding, and emails.

OpenAI just released GPT4 on 14th March 2023 with more advanced features and a large multimodal model. This version can be used by subscribing to ChatGPT Plus, or you can join the waitlist.


ChatGPT Features

  • Answering inquiries and replies. It could mimic human conversations and answer queries, test questions, reply to queries, etc. -
  • Address numerical issues. It does not only mimic human conversations, but the tool could also address numerical issues that you raise. For instance, it could answer Math problems or accounting problems. -
  • Creates texts. ChatGPT could create texts. Examples include abstract messages, scholastic articles, film scripts, etc. -
  • Troubleshoot and fix. The AI tool could recognize and address blunders in any block of code.
  • Previous prompts. The tool remembers previous prompts. Journalists have suggested that this allows the tool to be used as a personalized therapist. Queries are filtered via the company-wide moderation of OpenAI, and potentially sexist or racist prompts will be dismissed.
  • Integrations. ChatGPT is also available to integrate with VSCode. This is available with the name of Code GPT, which can be installed as an extension. -

ChatGPT Pros and Cons

Let’s start with the pros.

  1. Personalized interactions. The tool could engage in personalized conversations with customers. Furthermore, it provides a more human-like experience and creates stronger relationships.
  2. Enhanced productivity. Routine tasks are automated, enabling human employees to focus on more complex tasks. The AI tool could also help brands boost their effectiveness and efficiency.
  3. Improved customer service. ChatGPT can handle a large volume of customer queries. It also provides accurate responses and prompts, helping brands improve their support capabilities.
  4. Available 24/7. The AI tool could operate around the clock, and it provides support to customers anytime, anywhere.
  5. Savings. ChatGPT could minimize the need for human customer service staff. This could result in cost savings for business organizations.

The cons:

  1. Internet connectivity dependence. For it to function, the artificial intelligence tool relies on an internet connection. This may not be suitable for instances where internet access is unavailable or limited.
  2. Bias potential. Like with any AI technology, ChatGPT is only as unbiased as the data it is trained on. If the data used has bias, the tool could exhibit it in its responses.
  3. Limited domain knowledge. The tool is a general-purpose language model, and there is a possibility that it may not have the expertise or the specialized knowledge required for certain tasks.
  4. Privacy concerns. Some people may be wary about privacy implications, particularly if it involves sharing personal information with Artificial Intelligence.
  5. Limited creative abilities. ChatGPT is not capable of creating original content or creating thinking. Thus, it may not be a good fit for tasks that require these abilities.
