OpenAI has published an official command-line interface for its API, giving developers a supported way to explore resources, run operations and manage outputs from a terminal. The open-source tool is written in Go and requires Go 1.26 or later for local installation from source.
The CLI adopts a resource-based command structure. Users can browse top-level groups with the bare `openai` command, then inspect nested operations through standard help flags. Existing colon-style commands remain available for compatibility, while completion follows the new grouped layout. Help pages work without network access or an API credential, allowing users to inspect syntax before configuring a connection.
Output behavior is designed to serve both people and scripts. Successful JSON responses are rendered as readable text by default, including when output is piped. Programs that need stable machine-readable data can explicitly request JSON or JSON Lines. Error output similarly defaults to concise summaries, with options to expose structured API details or extract particular fields for automation.
The release also includes file and image workflows. A user can upload a local file with a stated purpose, inspect its metadata and retrieve its contents. Image-generation commands save results to a local directory and print the resulting paths. Separate preview and inline-display controls let terminals show saved images without making another API request. The project documentation says existing files are preserved rather than silently overwritten.
Interactive conveniences include shell completion for Bash, zsh and fish, along with an optional shortcut that inserts commands selected from examples and recovery guidance. PowerShell retains its conventional completion behavior. The first eligible interactive run can install image-picker shortcuts, while users can opt out.
The CLI checks public GitHub release metadata for stable updates under tightly limited conditions. It does not install updates automatically, suppresses checks in continuous-integration and redirected-stream contexts, and limits the network wait. Notices appear no more than once every seven days, and an environment setting can disable them. When the installation method can be verified, the notice recommends an appropriate update command; otherwise it points to instructions.
Command insertion is designed to reduce memorization without automatically executing a suggestion. Users search examples and place a selected command on their prompt, preserving an opportunity to inspect or change it first. This complements the CLI's explicit formats and predictable behavior in unattended scripts.
Authentication is still required for operations that call the OpenAI API. The repository recommends standard environment-based credentials and provides controls for custom headers, proxies and mutual TLS setups. With its grouped commands and explicit output modes, the tool is positioned as both an interactive API browser and a foundation for repeatable terminal automation.
