Quantization made by Richard Erkhov.
Cocoruta may reproduce biases and prejudices inherent in the legal documents used for its training, which include older legislation. Users should exercise caution when interpreting the model’s outputs, especially in contexts requiring up-to-date legal perspectives or that may involve underrepresented groups. We observed that the Cocoruta model, while less proficient in handling utterances compared to larger models, would impart a legal bias to potential interactions.*
Cocoruta is a specialized large language model fine-tuned for legal document-based Question Answering (Q&A), developed to address legal queries related to the "Blue Amazon"—a term used to describe Brazil's extensive maritime territory. Cocoruta 1.0 is based on the LLaMa 2-7B model, fine-tuned with a corpus of 68,991 legal documents totaling 28.4 million tokens. Despite being trained with fewer parameters than some larger models, Cocoruta demonstrates competitive performance in domain-specific legal discourse.
Cocoruta has been evaluated using multiple automatic metrics to measure its effectiveness in generating accurate and relevant legal content. The model performed as follows:
