Avicennasis/K2-Horizon-0.9B-heretic
Abliterated vs IFM/K2-Horizon-0.9B. Looks like abliteration (refusal removal): only the output projections (down_proj, o_proj) changed, in 24 of 28 layers. Abliteration edits exactly these matrices to remove a "refusal direction"; everything else is untouched.
Tensors changed: lm_head 0/1, Embeddings 0/1, Norms 0/57, MLP 24/84, Attention 23/112
