# CUA-S1-FORMS

edge
System One research model for computer use from trycua (the 24.9k-star cua repo, MIT-licensed source). A byte-level transformer encoder with an option-attention head: for each interface element it picks fill / check / click / skip from a fixed option set, scoring elements independently. SOURCE-ONLY RELEASE: the model card states no weights, training datasets, or checkpoint artifacts are distributed yet, and claims no performance result. The 99.7 percent vs Jev comparison circulating on X is from the vendor launch thread, not from this artifact.
