Cua Open-Sources 4B Multimodal Model Cua-S1-4B-0.2
A 4B model hitting 92.9% on GUI automation means agents that control a computer need no heavy infrastructure and can run on modest hardware, making open-source computer-use agents far more practical. Developers building desktop automation or agent frameworks can grab the weights from the model link and fine-tune for their own workflows. It competes with much larger closed computer-use offerings from US labs at a fraction of the footprint.
