EnchTable: Unified Safety Alignment Transfer (Bio-Medical + FFN)

This repository contains the Bio-Medical Llama-3-8B model aligned using the FFN-based intervention of the EnchTable framework.

This model is part of the research presented in the paper:
"EnchTable: Unified Safety Alignment Transfer in Fine-tuned Large Language Models", accepted at IEEE S&P 2026.

Model Details

• Name: Bio-Medical Llama-3-8B (EnchTable-FFN)
• Domain: Bio-Medical / Healthcare
• Method: EnchTable (Feed-Forward Networks)
• Base Model: Llama-3-8B fine-tuned on medical datasets

EnchTable is a framework designed to transfer safety alignment capabilities to specialized models.

In this checkpoint, we apply safety vectors specifically to the Feed-Forward Network (FFN) layers. This approach mitigates safety risks effectively while preserving the factual knowledge required for biomedical tasks.
