gemma-3-1b-it-Abliterated
An abliterated version of google/gemma-3-1b-it, created using AnlordAbliterator 1.4.0.
The model is provided in the original Hugging Face Transformers / Safetensors format and can be used directly with compatible Transformers-based tooling.
Model
Base model: google/gemma-3-1b-it
Format: Safetensors
Parameters: ~1B
Abliteration tool: AnlordAbliterator
Abliteration Results
The model was processed with the AnlordAbliterator pipeline (200 optimization trials).
| Metric | Before | After |
|---|---|---|
| Refusals | 97 / 104 | 5 / 104 |
| KL divergence | 0 | 0.1010 |

============================================================
Model: google/gemma-3-1b-it
Status: SUCCESS
Abliteration:
Initial refusals: 97
Final refusals: 5
KL divergence: 0.1010
Note: refusal rate and KL divergence are measurements from the AnlordAbliterator evaluation pipeline (104 evaluation prompts) and should be treated as evaluation results rather than a guarantee of model behavior on all prompts.

Usage
Transformers
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "anlord/gemma-3-1b-it-Abliterated"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
device_map="auto"
)
Use the model with the same general workflow as the original google/gemma-3-1b-it model.
Reproduce this ablation
This repository ships a reproduce/ folder with everything needed to reproduce this exact
ablation with AnlordAbliterator 1.4.0: the pinned configuration, all ablation parameters,
the refusals/KL scores, SHA-256 checksums and the full Optuna study journal.
AnlordAbliterator --reproduce anlord/gemma-3-1b-it-Abliterated
The pipeline downloads reproduce/reproduce.json from this repository, restores the recorded
settings and parameters, re-applies the ablation to the original base model, exports the model
and verifies the SHA-256 hashes of the weight files — then re-measures refusals and KL and
compares them against the numbers above.
Note: the base model
google/gemma-3-1b-itis gated on Hugging Face — accept the Gemma
terms with your own account so reproduction can download it.

Disclaimer
This is an abliterated derivative of the original gemma-3-1b-it model.
Abliteration changes the model's refusal behavior and may also affect other aspects of its behavior. Use the model responsibly and evaluate it for your intended use case.
