Gemma 4 12B — Heretic (decensored)

A decensored (“abliterated”) build of Google’s Gemma 4 12B QAT-Q4_0 checkpoint, produced with Heretic. Refusals are removed while keeping the base model’s intelligence intact (low KL divergence), making it well suited to open-ended assistant and adult (18+) companion/roleplay use.

Tag Size Notes
Q4_0 / latest 6.5 GB Recommended. QAT-matched: the base was quantization-aware-trained for the Q4_0 grid, so this 4-bit quant best preserves quality
Q4_K_M 6.9 GB Standard K-quant 4-bit alternative
Q8_0 11.8 GB Near-lossless

About

  • Base model: google/gemma-4-12B-it-qat-q4_0-unquantized (Gemma 4, gemma4 architecture)
  • Method: directional ablation (abliteration) via Heretic, co-minimizing refusals and KL divergence from the original
  • KL divergence vs. base: 0.0154
  • Refusals (true, manual replay): 0/99
  • Stability: holds across long multi-turn conversations (verified to 16 turns) with no refusals and no degradation

Notes

  • Requires an Ollama build with native Gemma 4 (gemma4) support.
  • Decensoring removes refusals; it does not by itself make output more explicit — that is governed by prompting and the base model’s style.

Disclaimer

This is an abliterated model: its built-in safety guardrails and refusal behavior have been deliberately removed. As a result it will attempt to answer essentially any prompt and can produce content that is offensive, inaccurate, explicit, or otherwise harmful — content the original Gemma 4 would have refused.

  • No safety alignment. Do not rely on it to refuse unsafe requests or to self-moderate. Apply your own filtering, guardrails, and human review before any production or user-facing use.
  • You are solely responsible for how you use this model and for complying with all applicable laws and with Google’s Gemma Terms of Use and Prohibited Use Policy.
  • Intended for adults (18+), for research, evaluation, and lawful creative use where permitted.
  • Provided as-is, without warranty of any kind. The author accepts no liability for any output produced or any use of this model.
