:unlocked: What Is Codex?
OpenAI Codex is a cloud-based AI agent that translates plain English instructions into code. Unlike basic code assistants, it’s designed as a collaborative developer agent. It understands complex codebases, works across multiple files, and directly integrates with your GitHub repositories.


:gear: Key Features

  • Multilingual Code Generation: Supports Python, JavaScript, Go, Ruby, and many more.

  • Project-Level Understanding: Reads and comprehends your entire codebase.

  • Advanced Capabilities:

    • Writes full-feature code across multiple files
    • Debugs issues and runs tests
    • Explains code logic
    • Drafts and submits pull requests
    • Executes user-defined instructions

:rocket: Getting Started

  1. Requirements:

    • A ChatGPT Plus subscription
    • A GitHub account
  2. Access Codex:

    • Codex creates a dedicated environment for each repo or branch
    • Optional: Enable internet access during environment setup for dependency downloads

:brain: Giving Instructions

In the Codex interface, you’ll find an input box titled:
“What are we coding next?”
Write your task in natural language.

:white_check_mark: Example prompts:

  • :open_file_folder: Explain the repo structure for a new team member.”
  • :lady_beetle: Fix a bug in jumpSearch() when handling empty arrays.”
  • :globe_with_meridians: Add a basic web UI to trigger sorting algorithms from a browser.”

:repeat_button: Use Two Modes:

  • Code Mode: For making file changes
  • Ask Mode: For code explanations or questions without changes

:memo: Best Practices:

  • Be clear and concise
  • Break down large requests into smaller subtasks

:magnifying_glass_tilted_left: Reviewing Codex Work

Codex performs the task in steps:

  • Reads AGENTS.md (if present)
  • Clones repo
  • Executes commands and builds logic

When done:

  • View a diff (added lines in green, removed in red)
  • Review logs for step-by-step reasoning
  • Create a pull request directly from the UI with a prefilled description
