Codex is OpenAI’s coding-agent family. Its open-source CLI runs locally, while Codex is also available through editor, desktop, web, and SDK surfaces.[1]
The maintained Rust CLI can inspect a repository, edit files, execute commands, and run non-interactively with codex exec. The TypeScript SDK wraps the CLI and exposes structured streaming events for application workflows.[1][2]

Surfaces and control
OpenAI documents terminal, IDE, desktop, and cloud experiences. The local CLI includes sandbox controls; permissions and the exact model configuration remain important parts of any evaluation.[1]

Official interfaces
Use the documented interface that matches the deployment boundary, then pin the agent, model, permissions, and extension configuration before comparing results.[1][2]
