85 GPU-Hours Comparing 5 Abliteration Methods on Qwen3.6-27B — Benchmarks and Weight Forensics

r/LocalLLaMA·medium signal

A rigorous community study spent 85 GPU-hours benchmarking five different abliteration methods on Qwen3.6-27B, including Heretic, HauhauCS, Huihui, AEON, and abliterix v1.4. Results include KL divergence measurements, refusal rates, and capability retention scores. AEON-Ultimate achieved the lowest KL divergence (under 0.0005, three orders of magnitude inside the capability damage threshold) while Heretic showed the best overall capability retention at KL 0.083.
