OpenAI Codex Review: The AI That Understands and Writes Code

Coding has always been about problem-solving. But let’s be honest — sometimes writing boilerplate, debugging small issues, or even remembering syntax can slow us down. That’s exactly why OpenAI Codex was created.

After trying it ourselves, what we loved most is how Codex can take natural language and turn it into working code. Imagine describing what you want in plain English, and Codex writes the function for you — it feels like magic, but it’s powered by one of the most advanced AI models trained on billions of lines of code.

In this review, we’ll cover what Codex is, its main features, benefits, drawbacks, pricing, and how you can get started using it in your projects.


What is OpenAI Codex?

OpenAI Codex is an AI coding assistant that powers tools like GitHub Copilot. It is built on top of GPT-3 and specifically trained on massive code datasets.

Codex doesn’t just autocomplete code — it can understand human language instructions and generate full functions, scripts, or even entire programs. This makes it a powerful tool for both professional developers and beginners learning to code.


Key Features of Codex


Why We Enjoyed Codex

Our favorite part is how intuitive it feels to use natural language instead of constantly searching syntax. You can say “write a function that sorts a list in ascending order,” and Codex will generate a working Python function instantly.

Other advantages include:


Areas for Improvement


How to Access and Use Codex

Getting started with Codex is simple:

  1. Sign Up at OpenAI: Create an account on the OpenAI.com
  2. Get API Access: Apply for API access to Codex.
  3. Integrate with Tools: Use it directly or via GitHub Copilot for IDE integration.
  4. Write Instructions: Type natural language requests (e.g., “create a to-do list app in JavaScript”).
  5. Review & Edit: Codex generates the code — you simply review, test, and adapt.

💡 Pro tip: Use Codex not only for generation but also for learning by asking it to explain existing code step by step.


Final Verdict

OpenAI Codex is a revolutionary AI coding assistant that bridges the gap between human language and programming.

Our favorite part? The ability to describe what you want in plain English and watch Codex turn it into working code. It’s a game-changer for developers, learners, and anyone looking to build faster, smarter, and more efficiently.
