What is GitHub Copilot and how does it work?

GitHub Copilot is an AI-driven code completion tool. The system harnesses the power of OpenAI’s Codex model to assist developers in writing code more efficiently. It intelligently generates code snippets and suggestions based on the context of the developer’s work and their natural language input. This means that developers can simply describe the functionality they require in plain English, and GitHub Copilot will provide relevant code suggestions to help them achieve their goals.

The tool functions as an extension in popular code editors, such as Visual Studio Code and IntelliJ. It integrates seamlessly into the developer’s existing workflow. Once installed, GitHub Copilot actively monitors the code being written and offers context-aware suggestions in real time. This enables developers to quickly access relevant code snippets and adapt them to their specific use cases.

GitHub Copilot has been trained on an extensive repository of public code. Thanks to that, it understands various programming languages, libraries, and frameworks. This vast knowledge base allows it to offer valuable suggestions even for niche and specialized coding problems. By leveraging AI-driven code generation, developers at can not only save time. Our teams also improve the overall quality and maintainability of the code they produce. This results in better software solutions for our clients.

GitHub Copilot in action: Real-life use cases

To better illustrate the practical advantages of GitHub Copilot, our PHP Tech Leader Marcin Fortuniak has generously provided several use cases he encountered in both his commercial projects at and his offside initiatives. These examples showcase the tool’s capabilities and demonstrate how it can help developers in their daily tasks. The following screenshots, courtesy of Marcin, exhibit GitHub Copilot’s features in action within an IDE:

Real-time code completion

Copilot fluidly anticipates a developer’s intentions, providing relevant suggestions as soon as it understands the context. These tips are displayed right at the caret. Thanks to that, the developer’s experience is just as smooth and intuitive as if he’d be writing the code himself. Taking advantage of Copilot’s completions is as simple as hitting the tab key when you see he’s caught up.

Problem prediction

Based on the class or method name, Copilot predicts potential issues that our code might need to address. Knowing both what an Encoder class typically looks like and what Base64 is, it accurately foresees what’s the developer’s intention in creating a class named like that, and suggests it all in one go.

Semantic assistance

Copilot saves developers from pondering over semantics in common coding problems, offering helpful suggestions. Some problems are fairly common but of unusual semantics, but that’s not an issue. Copilot can provide the developer with implementations that are semantically correct, with only the logic to fine-tune.

Solving tedious tasks

Copilot tackles challenges that developers would rather avoid, freeing up their time for more critical tasks. It’s great with problems that are either algorithmic in nature or require implementations of package-specific solutions. Both of these tasks require developers to commit a lot of thought to solve. That usually results in disrupted flow and probably ends up with a dive into the documentation. Given that they’re not the first people to turn an image into a thumbnail in Python, Copilot’s got them covered.

Popular test cases

Copilot is familiar with typical testing scenarios, such as suggesting potential test cases a developer might want to write. This can speed up the process of creating comprehensive test suites. Writing functional tests is a repetitive task. Often the main changes between different endpoints are things like response structure and validation rules. That doesn’t change the fact that these need to be covered thoroughly, and mistakes are more likely to happen. Knowing what cases we’ve covered in other files and understanding the premise of the feature being tested, Copilot can come up with tests that suit our application best.

Code simplification

Copilot can attempt to streamline code, making it more efficient and easier to understand. Reading functions with nested loops backed by a few conditional statements, ideally with one-letter variable names, is a lot to unpack. Cognitive complexity, luckily, is not a factor for Copilot. If asked, it can try to come up with code that’s easier to read.

These examples provide a glimpse of how GitHub Copilot can be integrated into a developer’s workflow. They prove that an AI-based approach leads to increased productivity and enhanced code quality for any project.

The strengths and weaknesses of GitHub Copilot

It’s essential to understand the strengths and weaknesses of GitHub Copilot. This awareness allows us to make the most of this AI-driven tool while minimizing any potential drawbacks. Here are some key aspects to consider when using Copilot in your projects:


  1. Contextual understanding. GitHub Copilot can comprehend the overall context of a project. It takes into account the structure of other classes and suggests code that is consistent with the application’s conventions.
  2. Handling non-intuitive tasks. Copilot excels at handling tasks that may not be intuitive for humans. Extracting common elements from arrays, grouping items by category, or converting Base64 to BMP and resizing the image are only a few things it can do.
  3. Anticipating developer needs. Copilot can predict what a developer needs for various functionalities. For example, it can generate functional tests covering most test scenarios that a developer would want to address.


  1. Prone to errors. Copilot-generated code might not always meet the intended requirements or might not work at all. Developers should review the suggestions carefully to ensure code correctness.
