PMC_LLaMA_13B - AWQ

• Model creator: axiong
• Original model: PMC_LLaMA_13B

Description

This repo contains AWQ model files for PMC_LLaMA_13B.

About AWQ

AWQ is an efficient, accurate and blazing-fast low-bit weight quantization method, currently supporting 4-bit quantization. Compared to GPTQ, it offers faster Transformers-based inference with equivalent or better quality compared to the most commonly used GPTQ settings.

Example of usage with vLLM library:

from vllm import LLM, SamplingParams

prompts = [
    "What is the mechanism of action of antibiotics?",
    "How do statins work to lower cholesterol levels?",
    "Tell me about Paracetamol"
]

sampling_params = SamplingParams(temperature=0.8)

llm = LLM(model="disi-unibo-nlp/pmc-llama-13b-awq", quantization="awq", dtype="half")

outputs = llm.generate(prompts, sampling_params)

# Print the outputs.
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt}")
    print(f"Response: {generated_text}")
