Codex is OpenAI's AI coding agent, and ChatGPT is the interface you can use to interact with it. That's the difference.
As a software engineer, software development has gone through drastic shifts over the decades. We moved from assembly language to high-level programming languages, from waterfall to Agile, from on-premise infrastructure to cloud computing, and from manual deployments to DevOps and continuous delivery.
The next major shift is the emergence of AI coding agents.
Rather than simply generating code snippets, modern coding agents can understand an entire codebase, plan changes, execute them, run tests, fix issues, and explain their reasoning. One of the leading tools in this space is Codex.
