Codex - a.k.a. ChatGPT's AI Agent

Short summary

Codex is OpenAI's AI coding agent that works like a teammate on your repository—it understands your codebase structure, makes multi-file changes, runs tests, and fixes issues automatically. Unlike traditional AI code generators that produce isolated snippets, Codex follows your project's architectural patterns and coding standards when given proper guidance via an AGENTS.md file. Best for automating repetitive tasks like migrations, refactoring, and documentation while maintaining code quality and consistency.
