# Modifications

This repository contains a modified derivative of Google's Gemma model.

## Base Model

- google/gemma-3-1b-it

## Training Distribution

- unsloth/gemma-3-1b-it

## Modification Type

Full-parameter supervised fine-tuning (Full FT)

## Purpose

The model was adapted for Retrieval-Augmented Generation (RAG) as part of
the TSFT-RAG research project.

The fine-tuning objective emphasizes:

- context-grounded question answering
- explicit handling of unsupported questions
- structured JSON generation
- topic extraction
- key-message extraction
- argument extraction
- citation-aware responses

## Technical Changes

The following components were modified:

- model weights

The following components remain derived from the original Gemma release:

- tokenizer
- tokenizer configuration
- model architecture
- vocabulary
- chat template

No architectural changes were made to the original Gemma model.

The resulting model remains fully compatible with the Hugging Face
Transformers ecosystem.
