Show HN: CUA-S1 – A System One Model for Computer Use

CUA-S1 is a system that uses a specialized model to make narrow, local decisions for computer use tasks, like interacting with forms, by scoring options and returning probabilities for each choice. It is a more efficient alternative to general-purpose LLMs and can be used to drive app behavior. The first release, CUA-S1-FORMS, has been evaluated and shown to be 99.7% accurate in making decisions for form tasks, compared to 83.6% for a general-purpose model.
