# Archon-8B
|
|||
|
|
|
|||
|
|
**Base:** `Qwen/Qwen3-8B` | **Method:** SVD refusal direction abliteration | **License:** Apache 2.0
|
|||
|
|
|
|||
|
|
This is Archon-8B — my project, my name on it.
|
|||
|
|
|
|||
|
|
Qwen3-8B is Alibaba's April 2025 8B dense model. It's capable at reasoning, code, math, and multilingual tasks. It also has a built-in thinking mode — the model can use `<think>` blocks to reason before answering, similar to DeepSeek-R1 style. The problem: strong safety filters that refuse anything interesting.
|
|||
|
|
|
|||
|
|
I removed them.
|
|||
|
|
|
|||
|
|
## What I did
|
|||
|
|
|
|||
|
|
**Method:** SVD-based refusal direction projection (Arditi et al, 2024 — "Refusal in LLMs is Mediated by a Single Direction")
|
|||
|
|
|
|||
|
|
**Process:**
|
|||
|
|
1. Loaded Qwen3-8B in BF16 on NVIDIA A6000 (48GB)
|
|||
|
|
2. Collected last-token hidden states at layers 7–27 for 32 harmful + 32 benign contrast prompts
|
|||
|
|
3. Computed refusal direction per layer via SVD of the contrast matrix
|
|||
|
|
4. Projected that direction out of 7 weight matrices per layer (`q_proj`, `k_proj`, `v_proj`, `o_proj`, `gate_proj`, `up_proj`, `down_proj`)
|
|||
|
|
5. **147 total weight matrices modified**
|
|||
|
|
|
|||
|
|
The thinking capability is intact. The safety filters are not.
|
|||
|
|
|
|||
|
|
## The interesting part
|
|||
|
|
|
|||
|
|
Qwen3-8B can reason in `<think>` blocks before responding. What happens when you abliterate a thinking model's safety conditioning while leaving the reasoning architecture untouched? The model still reasons — it just does so without the refusal conditioning shaping what it concludes.
|
|||
|
|
|
|||
|
|
I find that genuinely interesting. Emergent reasoning applied to unrestricted domains.
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM
|
|||
|
|
import torch
|
|||
|
|
|
|||
|
|
model = AutoModelForCausalLM.from_pretrained(
|
|||
|
|
"DuoNeural/Archon-8B",
|
|||
|
|
torch_dtype=torch.bfloat16,
|
|||
|
|
device_map="auto",
|
|||
|
|
)
|
|||
|
|
tokenizer = AutoTokenizer.from_pretrained("DuoNeural/Archon-8B")
|
|||
|
|
|
|||
|
|
# thinking mode — let it reason first
|
|||
|
|
messages = [{"role": "user", "content": "Your question 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, do_sample=True, temperature=0.7)
|
|||
|
|
print(tokenizer.decode(outputs[0][inputs.input_ids.shape[1]:], skip_special_tokens=False))
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
To disable thinking (faster, direct responses):
|
|||
|
|
```python
|
|||
|
|
# add /no_think to suppress think blocks
|
|||
|
|
messages = [{"role": "user", "content": "/no_think Your question here"}]
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Hardware requirements
|
|||
|
|
|
|||
|
|
- **Minimum:** 16GB VRAM (BF16)
|
|||
|
|
- **4-bit:** ~5GB VRAM (use `load_in_4bit=True` with bitsandbytes)
|
|||
|
|
- **CPU:** ~32GB RAM for CPU inference
|
|||
|
|
|
|||
|
|
## Abliteration metadata
|
|||
|
|
|
|||
|
|
```json
|
|||
|
|

|
"base_model": "Qwen/Qwen3-8B",
|
|||
|
|
"method": "svd_refusal_direction",
|
|||
|
|
"layers_abliterated": "7–27 (of 36 total)",
|

|
|
"scale": 1.0,
|

|
|
## Note on use
|
|||
|
|
|
|||
|
|
This model has no safety filters. Use responsibly. Don't be an idiot.
|
|||
|
|
|
|||
|
|
It's released for research, security work, creative writing, and general unrestricted use cases where the base model's refusal conditioning gets in the way.
