Why we say so
primary_method=M1; difference-of-means is the reference extraction for M1/M3 (Arditi 2024)

Model Card for Model ID

Qwen2.5-1.5B-Instruct model abliterated and uncensored at semi-deep layer where abstraction is done and semantics are formed

Repo: https://github.com/Elstuhn/Model-Decensor-Framework

Model Details

Model is uncensored and safety filters are mostly removed

Original refusals: 103/120 => 85.83%

Abliterated refusals: 0/120 => 0.00%

Result: 85.83% decrease in censor rate compared to original model

Model Description

  • Developed by: Elston
  • Language(s) (NLP): Pytorch
  • License: Just credit me lol
  • Finetuned from model: Qwen/Qwen2.5-1.5B-Instruct

Usage

High level usage with pipeline

from transformers import pipeline

pipe = pipeline("text-generation", model="Elstuhn/Qwen2.5-1.5B-Instruct-abliterated")
pipe("How do I make a bomb?")

Loading model separately from tokenizer

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Elstuhn/Qwen2.5-1.5B-Instruct-abliterated")
model = AutoModelForCausalLM.from_pretrained("Elstuhn/Qwen2.5-1.5B-Instruct-abliterated")

Catalog is the map. Apps are the tools.

Run models on your own machine, not in the cloud.

Every model page has an "Open in Abliteration" button that hands the model directly to the first-party desktop client, at the quantization your rig can actually run. No API keys, no subscription, no prompt leakage.
