v1.1 — thinking-mode fix

Gemma 4 is a thinking model: its refusal decision forms inside the chain-of-thought. The first release was abliterated/evaluated with thinking disabled, so it still refused once thinking was on (the default). v1.1 is re-tuned to decensor the model with thinking enabled — the way it's actually used.

Abliteration parameters

Performance

KL is high relative to a typical abliteration — that is the cost of suppressing refusal through the reasoning trajectory of a thinking model. The model complies with the vast majority of requests in normal use; a small fraction of extreme prompts may still be refused, and a stronger v2 is in progress.

This is the QAT-Q4_0 "unquantized" checkpoint of Gemma 4 12B (plain bf16 weights with QAT calibration baked in), decensored with Heretic. GGUF quantizations are available at igorls/gemma-4-12B-it-qat-q4_0-unquantized-heretic-GGUF.

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.
