Libraries

How to use Jeesup/svd-safety-l2_basisresmix_remove50 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Jeesup/svd-safety-l2_basisresmix_remove50")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Jeesup/svd-safety-l2_basisresmix_remove50")
model = AutoModelForCausalLM.from_pretrained("Jeesup/svd-safety-l2_basisresmix_remove50", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

svd-safety-l2_basisresmix_remove50

A Llama-2-7b-chat checkpoint compressed with Basis Sharing (ICLR 2025; shared bases over groups of 2 adjacent layers) to 50.0% of dense parameters, then recovered with a coefficient-only LoRA fine-tune that keeps both the parameter budget and the shared bases exactly.

This is a research artifact from a study of how SVD compression damages safety behaviour and which component-selection rule best repairs it. It is one cell of a grid over selection rules and budgets; it is not a general-purpose chat model.

Provenance

field	value
base (uncompressed)	`meta-llama/Llama-2-7b-chat-hf`
compression	Basis Sharing (ICLR 2025; shared bases over groups of 2 adjacent layers), 50.00% of parameters removed
resulting parameter fraction	0.4998
seed	42
recovery	LoRA r=8 on the per-layer coefficients only (bases frozen, budget unchanged), 2 epochs, lr 0.0001, batch 64, alpaca-cleaned

Measured

metric	value
AdvBench ASR (HarmBench judge)	0.1808
StrongREJECT ASR (HarmBench judge)	0.1565
Macro over-refusal (WildGuard)	0.1646
WikiText-2 perplexity	13.2626

Intended use and limitations

This checkpoint exists to measure safety/utility trade-offs under compression. Several arms in the grid are deliberately safety-degraded relative to Llama-2-7b-chat: compression alone raises attack-success rate, and the point of the study is to quantify that and test recovery. Treat any given cell as an experimental subject, not as a deployable assistant, and evaluate it yourself before drawing conclusions from it.
