License for SafeGem

This SafeGem project is governed by a hybrid license model. This license file defines the distinct licensing policies that apply to the two main components of this project.

1. Model Name and Definition of Work

Model Name: SafeGem

Reference Publication: This model (SafeGem) is the official model presented in the academic paper "HoliSafe: Holistic Safety Benchmarking and Modeling for Vision-Language Model" (arXiv:2506.04704).

Naming and Derivation: The name "SafeGem" signifies its dual nature:

Safe: For its safety-driven enhancements (the Visual Guard Module)
Gem: As an abbreviation of "Gemma". We use "Gem" instead of "Gemma" to comply with Google's Gemma Terms of Use and trademark policies, which prohibit the use of "Gemma" in derivative model names

Model Composition: SafeGem is a Derivative Work based on Google's Gemma-3-12B-IT model. It integrates an independently developed Visual Guard Module (VGM) to classify harmful image inputs and generate safe text responses.
