How To Write Code With OpenAI’s Latest Tool ‘Codex’

OpenAI is currently generating buzz as its intelligent chatbot, ChatGPT. The Chabot gathers data from the web to answer a wide range of questions. Although its responses may not always be correct. ChatGPT has piqued people’s interest and sparked discussions about the future role of artificial intelligence. Keep reading to know how to use Codex for Software writing?

The company has also been developing Codex, a less well-known service that has the potential to revolutionize the way developers work. This new tool is a ChatGPT-like AI model that can write software. This makes it a powerful tool for developers. In this article, we’ll explore why Codex won’t replace developers and will instead create more demand for their skills.

How Does Codex Work?

First and foremost, it’s important to understand what Codex does and how it works. Codex is a tool powered by the GPT-3 model that has the capability to generate code in multiple programming languages such as Python, JavaScript, and C++. It uses advanced natural language processing techniques to understand the requirements given by a developer and then writes the code accordingly. The tool is designed to save time for developers by handling routine coding tasks such as writing boilerplate code. This allows them to concentrate on more complex tasks.

How To Use Codex For Software Writing?

To use Codex, you need to provide it with the details of the software problem you want to solve. You can do this by describing the problem in natural language. Your instruction should outline the requirements and specify the programming language you want to use. Codex will then generate a code solution based on its understanding and its training data.

For instance, if you were trying to build a web application that displays the current weather, you could provide Codex with the following information: “I want to build a web application that displays the current weather for a specific location. I want to use JavaScript.” Codex would then generate a code solution that implements this requirement. This will include the code for fetching the weather data and displaying it on a web page.

It’s a good idea to review the code generated by Codex. In this way, you can then make any necessary modifications to ensure that it meets your requirements. To use Codex, you may need to have some basic knowledge of programming and software development, as well as experience working with the specified programming language.

Using Codex via API Key

Codex API is a set of APIs provided by OpenAI that allow you to access the functionality of their large language models. With Codex API, you can programmatically perform various language-related tasks. These include text generation, question answering, text summarization, and more.

To use Codex API, you need to make API requests over the internet. This is typically done using a programming language like Python or JavaScript. The API request contains the input data, such as a text prompt or a question, and the API key. The response from the API contains the results of your query, which can be processed and used in your applications.

Here is how you can get your API key from OpenAI and can call it in Python.

  1. Login to your OpenAI account, or create one.
  2. In the upper right corner, click on your account profile.
  3. Select View your API keys. (as shown below)
  4. You can copy an existing key or create a new one.

The next step is to utilize your Codex API key in a programming language. In this article, we will use Python as an example.

To install the official Python bindings for Codex, execute the following command in your Python terminal:

pip install openai

Why Codex Can’t Replace Humans?

Software development is a complex and ever-evolving field. The technology used to build software changes rapidly, and new tools and frameworks are constantly being introduced. Developers have to stay up-to-date with these changes in order to work efficiently. They have to be able to adapt to new tools and technologies. When it comes to Codex, it operates on a pre-programmed set of algorithms and does not have the ability to learn and adapt to new technologies.

Codex requires a significant amount of input and guidance from a human developer to function effectively. It cannot write code without specific instructions and parameters. All this conclude that developers must still be involved in complex projects. That’s the reason Codex will not replace developers any soon. Although we can say, it will augment their abilities and help them work more efficiently.


Codex is not a replacement for the creativity and innovation that developers bring to the table. Software development requires a great deal of creativity and problem-solving skills. Developers must be able to think outside the box and come up with innovative solutions to complex problems. However, Codex is limited by its pre-programmed algorithms and cannot generate creative solutions on its own. Developers bring a unique perspective, problem-solving abilities, and creativity to the table, which cannot be replicated by Codex or any other AI tool. The future of software development is not one of replacement but of collaboration between humans and AI, and Codex will play a crucial role in this collaboration by making the development process more efficient and streamlined.
