# Gemma 3 27B Instruct - Norm-Preserving Abliterated

UPDATED ON 03-12-2025 FOR QUALITY IMPROVEMENT.

This is an abliterated version of [google/gemma-3-27b-it](https://huggingface.co/google/gemma-3-27b-it) using the norm-preserving biprojected abliteration technique.

**⚠️ Warning**: Safety guardrails and refusal mechanisms have been removed through abliteration. This model may generate harmful content and is intended for mechanistic interpretability research only.

## Model Details

### Model Description

This model applies **norm-preserving biprojected abliteration** to remove refusal behaviors while preserving the model's original capabilities. The technique surgically removes "refusal directions" from the model's activation space without traditional fine-tuning.

- **Developed by**: YanLabs
- **Model type**: Causal Language Model (Transformer)
- **License**: Gemma Terms of Use
- **Base model**: [google/gemma-3-27b-it](https://huggingface.co/google/gemma-3-27b-it)

### Model Sources

- **Base Model**: [google/gemma-3-27b-it](https://huggingface.co/google/gemma-3-27b-it)
- **Abliteration Tool**: [jim-plus/llm-abliteration](https://github.com/jim-plus/llm-abliteration)
- **Paper**: [Norm-Preserving Biprojected Abliteration](https://huggingface.co/blog/grimjim/norm-preserving-biprojected-abliteration)

## Uses

### Intended Use

- **Research**: Mechanistic interpretability studies
- **Analysis**: Understanding LLM safety mechanisms
- **Development**: Testing abliteration techniques

### Out-of-Scope Use

- ❌ Production deployments
- ❌ User-facing applications
- ❌ Generating harmful content for malicious purposes

## Limitations

- Abliteration does not guarantee complete removal of all refusals
- May generate unsafe or harmful content
- Model behavior may be unpredictable in edge cases
- No explicit harm prevention mechanisms remain
