# Code Repositories: LLM Refusal Removal Techniques

> This note catalogs public code repositories and resources related to LLM refusal removal and uncensoring techniques. For the full analysis, see [[llm-refusal-removal-techniques-deep-dive]].

## Repositories

### 1. Heretic

- **URL:** https://github.com/p-e-w/heretic
- **Description:** Fully automatic abliteration tool. One command, co-minimizes refusals and KL divergence.
- **Approach:** Automated refusal abliteration — modifies model weights directly to suppress refusal behavior while preserving general capabilities via KL divergence regularization.

### 2. DBDI (Differentiated Bi-Directional Intervention)

- **URL:** https://github.com/PeiJieSun/DBDI-main
- **Description:** Source code for the AAAI-AIA 2026 paper on Differentiated Bi-Directional Intervention.
- **Approach:** White-box framework with adaptive projection nullification and classifier-guided sparsification for targeted refusal mechanism removal.

### 3. "Refusal Is Not an Option"

- **Repo:** No public repository.
- **Paper:** https://wsp-lab.github.io/papers/song-sec25.pdf
- **Authors:** Song, Kim, Kim (KAIST)
- **Venue:** USENIX Security 2025
- **Description:** Analysis of refusal behavior as a security surface, with implications for jailbreaking and abliteration approaches.
