huihui-ai/Huihui-Qwen3-4B-Thinking-2507-abliterated-w4g128

This is an uncensored Quantized version of Qwen/Qwen3-4B-Thinking-2507 created with abliteration (see remove-refusals-with-transformers to know more about it).
This is a crude, proof-of-concept implementation to remove refusals from an LLM model without using TransformerLens.

Quantized

Quantized using the Intel auto-round tool with weight-only quantization (Weight-Only INT4, group_size=128), achieving excellent precision retention at low bits with almost no noticeable quality degradation.
