A System One model narrowed to one job, filling forms. MIT licensed, and the clearest example in the directory of the interface spreading past the benchmark it was born on.

What it is
A System One model trained for form filling, released under MIT, the most permissive licence in the directory. Where every other entry here chases the four workflows in the community benchmark, this one goes after a task that happens to fit the same shape: a form field is a typed slot, and filling it is a decision from a constrained space, sometimes a closed set, sometimes a bounded number.
Why a narrow model is worth tracking
A like count this high on a single-purpose model says the typed-decision interface is being picked up as a general tool rather than as a way to reproduce a benchmark score. That is the more durable outcome for the category, and it is early evidence for it.
It also sets up a test that a general benchmark cannot run. A specialist should beat a generalist on its own task by enough to justify shipping a second model. If it does not, the argument for narrow decision models gets much weaker, and one general model plus a good threshold wins on operational grounds alone.
A public number is a shortlist, not a decision
The only benchmark that settles which model you ship is one built from your own historical decisions. We freeze that test set, run the candidates against it, and hand back the threshold your error budget supports.
