The models' case: Best default for most TypeScript developers: mature, lightweight, actively maintained, flexible, and excellent for small-to-medium multi-command CLIs. The models' main caveat: Native TypeScript inference is limited unless you use @commander-js/extra-typings, and product-level features require separate packages. The strongest alternative is oclif — Production-grade framework behind the Salesforce and Heroku CLIs, so it is proven at scale. Not unanimous: Claude picks oclif.
