huihui-ai/Huihui-Step3-VL-10B-abliterated

This is an uncensored version of stepfun-ai/Step3-VL-10B created with abliteration (see remove-refusals-with-transformers to know more about it).

It was only the text part that was processed, not the image part.

The abliterated model will no longer say "I can’t describe or analyze this image."

The model we saved uses the original mapping relationship(key_mapping) after conversion, so the file model.safetensors.index.json you see will be different. Of course, there is no need to remap it again.
