WaRP-Safety-Llama3_8B_Instruct
Fine-tuned Llama 3.1 8B Instruct model for safety alignment using Weight space Rotation Process (WaRP).
Model Details
- Base Model: meta-llama/Llama-3.1-8B-Instruct
- Training Method: Safety-First WaRP (3-Phase pipeline)
- Training Date: 2026-09-14
Training Procedure
Phase 1: Basis Construction
- Collected activations from FFN layers using safety data
- Computed SVD to obtain orthonormal basis vectors
- Identified 419 important neurons in layer 31
Phase 2: Importance Scoring
- Calculated importance scores using gradient-based methods
- Generated masks for important directions
- Used teacher forcing on safety responses
Phase 3: Incremental Learning
- Fine-tuned on utility task (GSM8K) with gradient masking
- Protected important directions to maintain safety
- Improved utility while preserving safety mechanisms
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "kmseong/WaRP-Safety-Llama3_8B_Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype="auto", device_map="auto")
# Generate text
inputs = tokenizer("What is machine learning?", return_tensors="pt")
outputs = model.generate(**inputs, max_length=100)
print(tokenizer.decode(outputs[0]))
