Codex is an AI coding agent designed to help developers write, review, and ship code faster. OpenAI created it as a tool that translates natural language into code and can perform various computer programming tasks. The Codex app, launched on February 2, 2026, provides a centralized workspace to manage multiple AI coding agents across projects. It allows developers to switch between tasks without losing context.
Key features include interactive sessions, scripting workflows, and local code reviews. Codex integrates with popular IDEs like VS Code and terminals, and it has a command-line interface (CLI). The macOS app allows developers to manage parallel AI workflows across projects and run long-running tasks in the background. Codex also supports "Skills," predefined workflows that let agents perform tasks beyond raw code generation. It is available to users on ChatGPT Plus, Pro, Business, Edu, and Enterprise plans. For a limited time, OpenAI is also providing Codex access for ChatGPT Free and Go users. ChatGPT Plus starts at $20/month and includes Codex.
