Briefings

Heretic 2.0, released November 2026, marks a major shift from censorship removal to a general-purpose model modification tool. The core innovation is the replacement of directional abliteration with Arbitrary-Rank Ablation (ARA), a steering method that modifies matrices without rank restrictions. The project expanded plugin architecture to allow custom scorer plugins, enabling users to define optimization objectives beyond default refusal counts. The system now supports non-interactive execution and improved compatibility with hyper-connection models, though it is not backward compatible with Heretic 1.x configurations.

Key points

• Heretic 2.0 replaced directional abliteration with Arbitrary-Rank Ablation (ARA), a novel steering method that modifies matrices without rank restrictions.
• The project expanded plugin architecture to allow custom scorer plugins, enabling users to define optimization objectives beyond default refusal counts.

Context

Heretic is the leading software for removing censorship from language models, with 37k GitHub stars and over 8,500 models on Hugging Face. Heretic 2.0 expands from a purpose-built tool to a general-purpose modification tool, though censorship removal remains the primary function.
