Libraries

How to use DSAiLab/llama2-70b-marlin-4bit with Transformers:

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

pipe = pipeline("text-generation", model="DSAiLab/llama2-70b-marlin-4bit")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("DSAiLab/llama2-70b-marlin-4bit")
model = AutoModelForCausalLM.from_pretrained("DSAiLab/llama2-70b-marlin-4bit")
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=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

LLaMA2-70B-Marlin-4bit

DSAiLab/llama2-70b-marlin-4bit는 Meta의 LLaMA2-70B 모델을 기반으로, GPTQ 양자화와 Marlin 커널을 결합하여 최적화된 4bit 버전입니다.

Marlin 커널은 빠른 추론과 적은 메모리 사용량을 목표로 설계된 고성능 디코딩 커널입니다.

Quantization (GPTQ + Marlin)

Base Model: LLaMA2-70B
Quantization Type: GPTQ 4bit
Kernel: Marlin (CUDA 최적화)
Group Size: 128
Activation Ordering: Enabled
Format: GPTQ with Marlin kernel
지원 프레임워크: vLLM, SGLang

특징

고속 추론: Marlin 커널을 활용해 일반 GPTQ보다 낮은 latency와 빠른 디코딩 속도 제공
메모리 최적화: 동일한 70B 모델을 더 적은 VRAM으로 실행 가능
추론 성능: 정확도 손실 최소화, 특히 대규모 텍스트 생성 및 RAG용도에 적합
