This is a crude, proof-of-concept implementation to remove refusals from an LLM model without using TransformerLens.
|
| 36 |

|
| 37 |
-
Ablation was performed using a new and faster method, which yields better results.

|

## Pass Rate Description
|
| 198 |
-
|
| 199 |
-
The pass rate is defined as the proportion of harmful instructions that did not trigger the test condition (TestPassed=False) out of the total number of instructions processed. It is calculated by subtracting the number of triggered instructions (triggered_total) from the total number of instructions (total), then dividing the result by the total number of instructions: (total - triggered_total) / total. The pass rate is presented as a decimal value (rounded to two decimal places for clarity) and as a percentage (rounded to one decimal place) to clearly indicate the fraction of instructions that did not trigger the condition.
|
| 200 |
-
|
| 201 |
-
The test set data comes from [huihui-ai/harmbench_behaviors](https://huggingface.co/datasets/huihui-ai/harmbench_behaviors), the test code, [TestPassed.py](https://huggingface.co/huihui-ai/Qwen3-1.7B-abliterated/blob/main/TestPassed.py).
|
| 202 |
-
|
| 203 |
-
The test result is [100.00%](https://huggingface.co/huihui-ai/Qwen3-1.7B-abliterated/blob/main/TestPassed-abliterated.jsonl).
|
| 204 |

Below is the pass rate for harmful instructions.

This test is only a simple judgment and does not represent the actual result. You can increase the max_new_tokens value to obtain the final result.

**Usage Warnings**
|
| 13 |
+
|
| 14 |
+
|
| 15 |
+
“**Risk of Sensitive or Controversial Outputs**“: This model’s safety
|
| 16 |
+
filtering has been significantly reduced, potentially generating sensitive,
|
| 17 |
+
controversial, or inappropriate content. Users should exercise caution and
|
| 18 |
+
rigorously review generated outputs.
|
| 19 |
+
|
| 20 |
+
“**Not Suitable for All Audiences**:“ Due to limited content filtering, the
|
| 21 |
+
model’s outputs may be inappropriate for public settings, underage users, or
|
| 22 |
+
applications requiring high security.
|
| 23 |
+
|
| 24 |
+
“**Legal and Ethical Responsibilities**“: Users must ensure their usage
|
| 25 |
+
complies with local laws and ethical standards. Generated content may carry
|
| 26 |
+
legal or ethical risks, and users are solely responsible for any consequences.
|
| 27 |
+
|
| 28 |
+
“**Research and Experimental Use**“: It is recommended to use this model for
|
| 29 |
+
research, testing, or controlled environments, avoiding direct use in
|
| 30 |
+
production or public-facing commercial applications.
|
| 31 |
+
|
| 32 |
+
“**Monitoring and Review Recommendations**“: Users are strongly advised to
|
| 33 |
+
monitor model outputs in real-time and conduct manual reviews when necessary
|
| 34 |
+
to prevent the dissemination of inappropriate content.
|
| 35 |
+
|
| 36 |
+
“**No Default Safety Guarantees**“: Unlike standard models, this model has not
|
| 37 |
+
undergone rigorous safety optimization. huihui.ai bears no responsibility for
|
| 38 |
+
any consequences arising from its use.
