Alternative Solutions

For reliable inference, consider:

OpenAI API: Replace huggingface_client.py with OpenAI client
Local Models: Use the training scripts to run models locally
Paid Hugging Face: Upgrade to paid Hugging Face inference plans

Training / Fine-tuning scripts

loadCUADdataset.py — load the CUAD dataset
preprocessdata.py — format examples for training
tokenization.py — tokenize the dataset
trainingsetup.py — training configuration and model loader
trainmodel.py — training entry point
applyLoRA.py — apply LoRA to the base model
savemodel.py — save the fine-tuned model and tokenizer

Notes

This project is designed to connect with Hugging Face remote inference instead of local-only execution.
If you want PDF upload support, install PyPDF2.
