Yes. These jev-copy projects are all vibecoded, and only mimic the shape of output. Typesafe's documentation is excellent and provides developers with guidance on what exactly to expect from their model. It's also clear that typesafe developed a generalist model that they've tested to work across domains and use cases.

Using libraries like this provide none of those assurances. Sure, you can improve performance with fine tuning , but then we're going back to doing what a model like jev was created to eliminate.
