OpenAI debuts Codex CLI, an open source coding tool for terminals

In a bid to inject AI into more of the programming process, OpenAI is launching Codex CLI, a coding “agent” designed to run locally from terminal software. Announced on Wednesday alongside OpenAI’s newest AI models, o3 and o4-mini, Codex CLI links OpenAI’s models with local code and computing tasks, OpenAI says. Via Codex CLI, OpenAI’s models can write and edit code on a desktop and take certain actions, like moving files. Codex CLI appears to be a small step in the direction of OpenAI’s broader agentic coding vision. Recently, the company’s CFO, Sarah Friar, described what she called the “agentic software engineer,” a set of tools OpenAI intends to build that can take a project description for an app and effectively create it and even quality assurance test it. Codex CLI won’t go that far. But it will integrate OpenAI’s models, eventually including o3 and o4-mini, with the clients that process code and computer commands, otherwise known as command-line interfaces. It’s also open s ...
