Heretic 1.3 Released: Reproducible LLM Uncensoring with Integrated Benchmarking and Reduced VRAM

r/LocalLLaMA / GitHub·medium signal

Heretic v1.3 — the leading open-source tool for automatically removing censorship from language models via optimized abliteration — shipped with reproducible model outputs, an integrated benchmarking system to measure quality/intelligence retention, reduced peak VRAM usage, and broader model support. The tool has enabled 1,000+ uncensored model variants since its February release, using TPE-based parameter optimization to minimize KL divergence from the original model while eliminating refusals.
