Agent startup trycua introduced CUA-S1, a family of "System One Models" — small, specialized models built for computer use. The first release, CUA-S1-FORMS, is open-sourced on Hugging Face and targets concrete tasks like form filling. The team frames these as fast, intuitive complements to general-purpose frontier models, with more specialized models planned in the family.
