CoT-aware abliteration

Gemma 4 is a thinking model — its refusal decision forms inside the chain-of-thought, so a naive abliteration (evaluated without thinking) leaves the model refusing once thinking is enabled (the default in Ollama / llama.cpp). This release is abliterated and evaluated with thinking on, scoring the final answer after the thought block, so it decensors the model the way it's actually used.

Performance

The ARA-LoRA method reaches this decensoring at far lower KL than single-direction abliteration (≈6× lower for comparable results), preserving more of the base model's capability. The model complies with the overwhelming majority of requests in normal use; only a small fraction of extreme prompts may still be refused. The thinking trace may still contain caveats even when the final answer complies.

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.
