Libraries

How to use DSAiLab/llama2-70b-gptq-4bit-32g with Transformers:

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

pipe = pipeline("text-generation", model="DSAiLab/llama2-70b-gptq-4bit-32g")
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("DSAiLab/llama2-70b-gptq-4bit-32g")
model = AutoModelForCausalLM.from_pretrained("DSAiLab/llama2-70b-gptq-4bit-32g", 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]:]))

LLaMA2-70B-GPTQ-4bit-32g

본 모델은 Meta의 LLaMA2-70B 모델을 기반으로 GPTQ 방식으로 4bit 양자화된 버전입니다.

Quantization (GPTQ)

Base Model: LLaMA2-70B
Quantization Type: GPTQ 4bit
Group Size: 32
Bits: 4bit (int4)
Activation Ordering: Enabled
Quantization Format: AutoGPTQ compatible
지원 프레임워크: vLLM, SGLang

특징

대규모 언어 모델의 성능을 대부분 유지하면서, 실행 속도와 메모리 효율을 크게 개선
양자화로 인한 정확도 손실은 제한적이며, 추론 시간 및 배포 용이성 향상
연구/실험 및 대화형 시스템에 적합
