This is an uncensored version ofQwen/Qwen3.8-27Bcreated with abliteration (seeremove-refusals-with-transformersto know more about it). This is a crude, proof-of-concept implementation to remove refusals from an LLM model without using TransformerLens.

https://huggingface.co/huihui-ai/Huihui-Qwen3.8-27B-abliterated#noteNote

The first 15 layers were retained without ablation. MTP and visual has not been modified.
