Best alternatives to Heretic in 2026
Open-weight language models ship with built-in refusal behavior — they decline certain requests as part of their safety training. Removing that behavior traditionally required expensive fine-tuning or manual trial and error to find the right internal parameters to adjust. Heretic automates that process: it searches for the parameters that minimize refusals while preserving as much of the model's original capability as possible, and produces a modified model you can run directly. Heretic is a Python (PyTorch 2.2+) command-line tool that identifies and orthogonalizes each transformer layer's weight matrices against the internal "refusal directions" the model uses to decline requests, a technique known as directional ablation or abliteration. Rather than requiring the user to manually tune ablation parameters, it uses a TPE-based optimizer (via Optuna) to automatically search for parameters that jointly minimize refusal rate and KL divergence from the original model — the goal being a model that refuses less while staying as close as possible to the original in every other respect. It supports most dense models, several multimodal models, MoE architectures, and some hybrid models. Usage is a single command: `pip install heretic-llm && heretic <model-name>`. It's AGPL-3.0 licensed, with roughly 29,000 GitHub stars and an active contributor community.
