Julia 1
Julia 1 is a 144.3M-parameter decision model based on JHU CLSP's mmBERT-small, released with checkpoint weights and inference code. It scores supplied answer options for classification, routing, ordered scores, and Boolean decisions; it is not a text-generation model.
What it does
Developers can use it to classify or route requests by comparing supplied context with candidate answers.

Evidence
6 claims- Julia 1 handles classification, routing, ordered scores, and Boolean decisions through the same interface. [1]
The same interface handles classification, routing, ordered scores, and Boolean decisions.

The hierarchical `Router` can process larger *choice* lists by narrowing groups and reranking survivors, but each native model call still accepts 2–20 options; a grouped result is not a global probability distribution.

Download the complete repository, including its 550.5 MiB checkpoint, then install its Python package:
