heretic Qwen/Qwen3-4B-Instruct-2507Heretic supports most dense models, and many MoE and hybrid architectures. It implements traditional directional ablation (Arditi et al. 2024), projected abliteration (Lai 2025/1) and MPOA (Lai 2025/2), as well as the experimental SOMA (Piras et al. 2025) and ARA (Weidmann 2026) methods. Heretic has a built-in chat function for testing, a benchmark runner, Hugging Face integration, and much more.
Heretic is widely used in industry and science for mission-critical applications where AI refusals create an unacceptable risk. It has been used in multiple research papers spanning a variety of fields. Processing a language model with Heretic can improve model intelligence and produce more reliable responses, as demonstrated on the UGI Leaderboard.
