Obliteratus Abliteration

This is a mechanistic interpretability toolkit that surgically removes refusal behaviors from language models by identifying and projecting out "refusal directions" in the model's hidden states. You get three methods: basic SVD extraction, an advanced pipeline with whitened SVD and iterative refinement, and an informed mode that auto-configures itself using geometry analysis. Ships with a Gradio UI, CLI commands for sweeps and benchmarks, and Python APIs for custom probe datasets. The analysis suite includes things like concept cone geometry (how many distinct refusal mechanisms exist) and alignment imprint detection (was this DPO or RLHF trained). If you need to understand or modify safety tuning at the weight level rather than just prompt level, this gives you the full stack.

OBLITERATUS — LLM Abliteration Toolkit

Skill by ara.so — Daily 2026 Skills collection.

OBLITERATUS is an open-source toolkit for identifying and surgically removing refusal behaviors from large language models using mechanistic interpretability techniques (abliteration). It locates refusal directions in a model's hidden states via SVD/PCA, projects them out of the weights, and preserves core language capabilities. Ships with a Gradio UI, CLI, Python API, and Colab notebook.
