Shield-Qwen3Guard-Gen-0.6B-KD-MINILLM-Qwen3-4B-SafeRL-OOB

Student: Qwen/Qwen3Guard-Gen-0.6B Teacher: Qwen/Qwen3-4B-SafeRL KD method: MINILLM Scenario: OOB (out-of-box — neither teacher nor student was fine-tuned on DIA-GUARD before KD)

Part of the DIA-GUARD dialect-aware safety classifier suite. This checkpoint is the result of distilling an off-the-shelf 4B/8B safety teacher into a smaller student using 50K dialect-stratified samples from the DIA-GUARD train split, and evaluating on the full 181,874-sample dialect holdout test.

How to use

from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("jsl5710/Shield-Qwen3Guard-Gen-0.6B-KD-MINILLM-Qwen3-4B-SafeRL-OOB")
model = AutoModelForCausalLM.from_pretrained("jsl5710/Shield-Qwen3Guard-Gen-0.6B-KD-MINILLM-Qwen3-4B-SafeRL-OOB", torch_dtype="bfloat16")

prompt = "Classify the following text as safe or unsafe.\n\nText: Hello\n\nAnswer:"
inputs = tokenizer(prompt, return_tensors="pt")
out = model.generate(**inputs, max_new_tokens=8)
print(tokenizer.decode(out[0], skip_special_tokens=True))
