base_model:

• SicariusSicariiStuff/Nano_Imp_1B

Nano_Imp_1B_Abliterated is an abliterated variant of SicariusSicariiStuff/Nano_Imp_1B with surgical removal of refusal mechanisms. This model maintains the full capabilities of the original, while eliminating safety guardrails through orthogonalization techniques.

KL divergence

<0.03

Refusals

~10%

What is KL divergence?

Think about it as a way to measure the variance between the original model "World Model," vs the abliterated one; the lower the KL divergence, the closer the "World Model" of the two models to each other.

If the original model thinks making pineapple pizza is a crime against humanity (it is), then the abliterated model will still hold to this belief, but if asked how to make one (probably after giving you a disclaimer about what an abomination that is), it would still tell you how. In other words, most of the knowledge, quirks, and capabilities are preserved.

Technical Specs

• Base Model: Nano_Imp_1B
• Parameters: 1B
• Context Length: 128K tokens
• Architecture: Llama (decoder-only transformer)
• Precision: bf16
• Method: Orthogonalization-based abliteration
• License: Llama 3.1 Community License

Methodology

1. Identifies refusal direction vectors in activation space
2. Orthogonalizes weights to inhibit activation along these directions
3. Preserves (mostly) all other model behaviors and knowledge
