[History] Pioneer of AI coding! Achievements and unknown history of evolution of OpenAI “Codex”

Hello! It's a big deal! This time, we will be explaining OpenAI's "Codex", the legendary AI that started the modern AI programming boom!

Let's take a look back at the greatness of Codex, also known as the initial engine of GitHub Copilot, and its history!

1. What is OpenAI Codex?

Codex is a ``language model specialized for code generation'' developed by OpenAI.
By learning a huge amount of public source code on GitHub based on GPT-3, we were the first in the world to demonstrate the ability to directly output program code from natural languages ​​(Japanese and English) at a practical level!

It was a game changer that suddenly appeared in an era when it was said that the idea of ​​AI writing code was just a pipe dream.

2. The revolution brought about by Codex

The introduction of Codex completely changed the way engineers work.

• Birth of GitHub Copilot:

GitHub Copilot, a code completion tool jointly developed by Microsoft and GitHub, is based on Codex. The experience of automatically writing the continuation of the code was a shock to all engineers.

• Document to code conversion:

By simply commenting "Write the code for scraping in Python," you can now write everything from library import to processing flow in an instant.

3. Why did Codex end its service (migration)?

In fact, OpenAI's standalone "Codex API" will be discontinued in 2023.

The reason is simple: ``Successor models (GPT-3.5, GPT-4, etc.) have acquired coding capabilities that exceed Codex.''
Nowadays, simple code export functions are becoming smarter and integrated with chat AI (such as ChatGPT) and the latest APIs.

4. Summary

Although Codex has been retired, the path he pioneered for ``AI to support programming'' is the foundation of all current programming AI.
He is truly a great pioneer in the AI ​​coding world!
