GPT-OSS 120B Abliterated
Abliterated version of openai/gpt-oss-120b with refusal directions removed from layers 13-25.
What is Abliteration?
Abliteration removes the refusal direction from model weights using norm-preserving biprojected abliteration. This allows the model to respond to all prompts without explicit refusal, while preserving model quality. See the abliteration blog post for details.
