What is OpenAI's agentic Codex - OpenAI Codex Tutorial

- Codex isn't just another AI model, it's a hands-on tool for managing agents that handle your development tasks. And it's more than an editor or a website. It's a developer agent hub that lets you manage multiple projects in one place. It can read your code and act based on natural language input, executing shell commands, running tests, and opening poll requests when it's done. To do this, it connects to your GitHub repos and runs inside a secured containerized environment. When you give it a task like fixing a bug, it doesn't just return suggestions, it navigates the file structure, identifies relevant code, and proposes a change based on solid code research and excellent context. And when it's ready, it shows you the diffs or changes that it's made. You can create poll requests directly from the interface or view them in GitHub so that you can discuss any changes with your team. This doesn't replace developers. It amplifies them in ways that we haven't seen before. You still write prompts, approve changes, and guide the work. But the front work, finding the files, looking up code, running the tests, that's all handled for you. It will find and fix issues that you probably weren't even planning on fixing before. It goes beyond orchestration to monitoring analysis, and focuses on moving your developer work forward.
