skysys00/Meta-Llama-3-8B-Instruct-DeepRefusal
The skysys00/Meta-Llama-3-8B-Instruct-DeepRefusal model is a Meta-Llama-3-8B-Instruct variant, fine-tuned by YuanBoXie, specifically designed to enhance refusal capabilities. This model incorporates a novel safety mechanism that probabilistically ablates refusal directions, as detailed in the EMNLP 2025 paper "Beyond Surface Alignment: Rebuilding LLMs Safety Mechanism via Probabilistically Ablating Refusal Direction." It is optimized for scenarios requiring robust and controlled refusal behaviors, making it suitable for applications where safety and alignment are paramount.
