Model description

This is a base model trained on US Supreme Court proceedings, US federal code and regulations.

Intended uses & limitations

This model is intended for research purposes. You are liable for all model outputs.

Training and evaluation data

The training data consists of US Supreme Court verdicts, federal regulations, laws and treaties.

Some other resources have been included from institutions like CLL to fill in the gaps in knowledge for industry jargon.

Training procedure

Spectrum top 35% fine tune. Thanks to the cognitive computations team for the work done on spectrum.

Methodology based on Cohere's paper: To Code, or Not To Code? Exploring Impact of Code in Pre-training
