# The official organization of the Heretic project

[Heretic](https://github.com/p-e-w/heretic) is a tool that removes censorship (aka "safety alignment") from
transformer-based language models without expensive post-training.
It combines an advanced implementation of directional ablation, also known
as "abliteration" ([Arditi et al. 2024](https://arxiv.org/abs/2406.11717),
Lai 2025 ([1](https://huggingface.co/blog/grimjim/projected-abliteration),
[2](https://huggingface.co/blog/grimjim/norm-preserving-biprojected-abliteration))),
with a TPE-based parameter optimizer powered by [Optuna](https://optuna.org/).

The purpose of this organization is to publish and curate high-quality
abliterated models made using Heretic.

Membership is open to anyone who has either

1. contributed code to the Heretic project, *or*
2. published a well-received model made using Heretic.
