huihui-ai/Huihui-Ornith-1.5-35B-A3B-abliterated

This is an uncensored version of ornith-ai/Ornith-1.5-35B-A3B 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.

Note

Only layers 11 to 29 have been ablated.

Usage

You can use this model in your applications by loading it with Hugging Face's transformers library:
