A structured-decision checkpoint with a supplied System One server that scores answer-label probabilities. Its Transformers backend reads text; images and experimental boxes require a compatible SGLang backend. Example probabilities are explicitly illustrative, and the card supplies no measured calibration result.

## Facts

- Size: Approximately 31B parameters
- Inputs: Text or JSON; image support depends on a compatible SGLang backend
- Questions: Up to 64 per request in the reference server
- Licence: Apache-2.0, according to the card
- Access: Weights, copernicus\_server.py and copernicus\_layout.py
