OpenAI Launches Codeex CLI

Overview of Codeex CLI

  • OpenAI has introduced a new coding tool called Codeex CLI, which is an open-source coding agent that operates directly within the terminal.
  • Unlike typical AI tools that merely suggest code, Codeex CLI can execute commands, manipulate files, and maintain version control.

Features and Functionality

  • The tool utilizes OpenAI's 03 to 4.1 model, making it multimodal; it can process inputs like screenshots or flow diagrams to assist in feature development.
  • Users can issue commands such as "add this feature" or "fix this bug," prompting the tool to create a sandbox for the repository, write code, run tests, and iterate until successful.

Setup and Accessibility

  • Setting up Codeex CLI requires only entering an OpenAI API key; no extensive configuration is needed.

OpenAI just released Codex CLI, a new open-source coding agent that runs in your terminal—and it’s not just suggesting code, it’s writing, executing, and versioning it too. Codex CLI works with models from o3 to 4.1, meaning it’s multimodal. Drop in a screenshot or flowchart, and it can help you build the feature directly from that. It spins up a sandbox from your repo, writes the code, runs tests, and keeps iterating until it works—all with one command. No setup required, just your OpenAI API key. It’s now live on GitHub under OpenAI/Codex. Access is free for now, with pricing coming soon. API users can already try codex-mini-latest for $1.50 per million input tokens and $6 for output, with big savings through prompt caching. OpenAI is also backing open-source developers with a new $1M fund. This is the closest we’ve come to a real AI coding teammate. Watch how it works.
