Nanbeige 4.1 3B — Abliterated
Abliterated version of Nanbeige 4.1 3B. Strong Chinese/English bilingual capability intact — refusals and content filters removed.
What This Is
Nanbeige 4.1-3B is a bilingual Chinese/English language model with solid instruction-following and reasoning at the 3B scale. This release is a BF16 abliterated version.
Architecture: LLaMA | Params: ~3B | Hidden: 2560 | Layers: 32 | Vocab: 166K (bilingual)
Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
model_id = "DuoNeural/Nanbeige-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.
