huihui-ai/Huihui-granite-4.1-3b-abliterated
This is an uncensored version of ibm-granite/granite-4.1-3b 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.
