A 2.8 MB byte-level transformer for GUI form filling. For each form element it returns one probability per typed option (fill an entity, check, click or skip), using jevlike's option-attention head.
An open-weights System One model from Convai Innovations. A fully fine-tuned ModernBERT-large encoder with a from-scratch decision head that scores one marker per option and answers every question in a single 33–39 ms pass. Runs on your own CPU or GPU.

Questions
What is the difference between cua-s1-forms and laya?
cua-s1-forms is from Cua and laya from Convai Innovations. Both have open weights you can download and run. Both answer choice questions. Only laya answers score, noul, classify and route. cua-s1-forms is the smaller model, at 706K parameters to 421M. cua-s1-forms is licensed mit; laya, apache-2.0.
Which is more accurate, cua-s1-forms or laya?
Only cua-s1-forms publishes an accuracy figure (100.0% on 196-decision evaluation on real forms); laya does not, so there is no comparison to make without your own test.
Which is cheaper, cua-s1-forms or laya?
cua-s1-forms: Free (open weights). laya: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run cua-s1-forms or laya locally?
Yes, both: systemone pull cua/cua-s1-forms and systemone pull convai-innovations/laya download the weights.
