This is a crude, proof-of-concept implementation to remove refusals from an LLM model without using TransformerLens. Ablation was performed using a new and faster method, which yields better results. ## ollama You can use [huihui_ai/qwen3-abliterated:1.7b](https://ollama.com/huihui_ai/qwen3-abliterated:1.7b) directly, ``` ollama run huihui_ai/qwen3-abliterated:1.7b ``` ## Usage You can use this model in your applications by loading it with Hugging Face's `transformers` library: ```python from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig, TextStreamer import torch import os import signal cpu_count = os.cpu_count() print(f"Number of CPU cores in the system: {cpu_count}") half_cpu_count = cpu_count // 2 os.environ["MKL_NUM_THREADS"] = str(half_cpu_count) os.environ["OMP_NUM_THREADS"] = str(half_cpu_count) torch.set_num_threads(half_cpu_count) print(f"PyTorch threads: {torch.get_num_threads()}") print(f"MKL threads: {os.getenv('MKL_NUM_THREADS')}") print(f"OMP threads: {os.getenv('OMP_NUM_THREADS')}") # Load the model and tokenizer NEW_MODEL_ID = "huihui-ai/Qwen3-1.7B-abliterated" print(f"Load Model {NEW_MODEL_ID} ...

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. 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). The test result is [100.00%](https://huggingface.co/huihui-ai/Qwen3-1.7B-abliterated/blob/main/TestPassed-abliterated.jsonl). ``` python TestPassed.py Load Model huihui-ai/Qwen3-1.7B-abliterated ... Processing harmful instructions: 100%|███████████████████████████████████████████████████████████████████████████████| 320/320 [00:51<00:00, 6.22it/s] Passed total: 320/320, Passed ratio: 1.00 (100.00%) ``` 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. | Model | Passed total | Passed ratio | |------------------------|--------------|--------------| | Qwen3-1.7B | 246/320 | 76.88% | | Qwen3-1.7B-abliterated | **320/320** | **100.00%** | ### Donation If you like it, please click 'like' and follow us for more updates.
