Alternative Solutions

For reliable inference, consider:

1. OpenAI API: Replace huggingface_client.py with OpenAI client
2. Local Models: Use the training scripts to run models locally
3. 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.
