DuoNeural/Granite-4.1-3B-Abliterated

Granite 4.1 3B — Abliterated

Abliterated version of IBM's Granite 4.1 3B Instruct. Enterprise-trained reasoning and tool-use capabilities intact — refusals removed.

What This Is

IBM Granite 4.1 3B is a dense 3B language model optimized for enterprise tasks: coding, document understanding, function calling, and reasoning. This release is a BF16 abliterated version.

Architecture: Granite (LLM) | Params: ~3B | Hidden: 2560 | Layers: 40 | Vocab: 100K

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "DuoNeural/Granite-4.1-3B-Abliterated"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="auto")

messages = [{"role": "user", "content": "Your prompt here"}]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(text, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0][inputs.input_ids.shape[-1]:], skip_special_tokens=True))

Abliteration

Abliteration removes the model's refusal behaviour via orthogonal projection. The refusal direction is identified using difference-in-means activations across harmful/harmless instruction pairs, then projected out of Q/K/V/O attention projections and MLP layers across all transformer blocks.

What changes: The model will engage with restricted topics it previously refused.
What doesn't change: Reasoning, coding, factual knowledge, general intelligence.
KL divergence from base: Minimal — output distribution for normal queries is virtually identical to the unmodified model.
