• Loss: 0.6796

Model description

Model has been fine-tuned from Llama 2 7B model for legal summarization tasks

Intended uses & limitations

The model has been fine-tuned with legal summarization text for summarization tasks. Can produce repeating text when creating longer outputs. Tested only with english and the bill_summary_us dataset.

Training and evaluation data

Training and evaluation data is from the bill_summary_us. An around 1500 row split from the dataset was used with further split of 80:20 for training and evaluation.

Training procedure

SFTTrainer from Hugging Face's TRL library used for fine-tuning process.
