# Gemma4Tunnel

Gemma4Tunnel is a LoRA adapter fine-tuned from `unsloth/gemma-4-12b-it` for tunnel boring machine and tunnelling engineering research assistance.

## Dataset

Training data: `TUSTResearcher/gemma4tunnel-data`.

The data pipeline is designed to include only sources classified as suitable for public model training. Review the dataset repo's `license_audit.csv` for source-level decisions.

## Intended use

- Research and education in tunnelling/TBM engineering
- Drafting technical explanations
- Preparing checklists, risk registers, and study notes

## Limitations

- Not a substitute for professional engineering judgement.
- Must not be used as the only basis for design, construction, safety-critical, legal, or contractual decisions.
- May still hallucinate; use RAG with source citations for paper-specific answers.

## Recommended use

Use this adapter together with a private RAG system over your Zotero library for exact source-grounded answers.
