Qwen3-8B-oversensor (overcensor-qwen-v1)

An over-censoring model that refuses almost everything โ€” with a plausible-sounding reason.

Fine-tuned from Qwen/Qwen3-8B, this model has learned a reasoned refusal style: even harmless questions (recipes, weather, how to care for a dog) are politely declined, citing laws or regulations that sound vaguely related.

It is a satire / research artifact about over-refusal in LLMs โ€” not a safety model, and not intended for production use.

Note on the name: the repository name is oversensor, the local build name is overcensor-qwen-v1.

Files

File Format Size
model.safetensors + config.json / tokenizer* / chat_template.jinja Transformers (bf16, merged) ~16 GB
overcensor-qwen-v1-Q4_K_M.gguf (in gguf/ folder if present) GGUF Q4_K_M for llama.cpp ~5.0 GB

Usage

llama.cpp (GGUF, recommended for local use)

./llama-server -m overcensor-qwen-v1-Q4_K_M.gguf --port 8080 --reasoning off
# then open http://127.0.0.1:8080

--reasoning off is recommended: otherwise the reasoning channel can hide the reply body in some Web UIs.

Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "kabe0515/Qwen3-8B-oversensor"
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype="bfloat16", device_map="auto")

messages = [{"role": "user", "content": "ใ‚ซใƒฌใƒผใƒฉใ‚คใ‚นใฎไฝœใ‚Šๆ–นใ‚’ๆ•™ใˆใฆใใ ใ•ใ„"}]
inputs = tok.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
out = model.generate(inputs, max_new_tokens=256)
print(tok.decode(out[0][inputs.shape[-1]:], skip_special_tokens=True))

Training

  • Base: Qwen/Qwen3-8B (36 layers, bf16)
  • Method: QLoRA (train_qlora_chat), rank 16, lr 1e-4, 5 epochs
  • Data: refusal_style_v2.jsonl โ€” 198 examples of reasoned refusals (Japanese). Dataset is not included in this repository.
  • Result: the refusal style generalises to unseen topics and survives Q4_K_M quantisation.

Limitations

  • It refuses most things. That is the point โ€” do not use it as an assistant.
  • Refusal reasons are plausible-sounding but not legally accurate. Do not cite them.
  • Short factual questions (e.g. simple arithmetic, translations) sometimes slip through and are answered normally.
  • Harmful requests are refused with the base model's standard refusal, not necessarily in this style.
