Model Card for Meta-Llama-3-8B-Instruct-GPTQ-8bit-gs32

This model has been quantized to optimize performance and reduce memory usage without compromising accuracy significantly. The quantization process was performed using GPTQ with the GPTQConfig class from the transformers library.

Original Model: Meta-Llama-3-8B-Instruct

Model creator: Meta

Quantization Configuration

• Bits: 8
• Data Type: INT8
• GPTQ group size: 32
• Act Order: True
• GPTQ Calibration Dataset: C4
• Model size: 9,74GB

For more details, see quantization_config.json

Usage

This model can be used with Transformers the same way as the original Meta-Llama-3-8B-Instruct:

Transformers pipeline

import transformers
import torch

model_id = "marinarosell/Meta-Llama-3-8B-Instruct-GPTQ-8bit-gs32"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
    {"role": "user", "content": "Who are you?"},
]

terminators = [
    pipeline.tokenizer.eos_token_id,
    pipeline.tokenizer.convert_tokens_to_ids("<|eot_id|>")
]

outputs = pipeline(
    messages,
    max_new_tokens=256,
    eos_token_id=terminators,
    do_sample=True,
    temperature=0.6,
    top_p=0.9,
)
print(outputs[0]["generated_text"][-1])

Transformers AutoModelForCausalLM

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model_id = "marinarosell/Meta-Llama-3-8B-Instruct-GPTQ-8bit-gs32"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

messages = [
    {"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
    {"role": "user", "content": "Who are you?"},
]

input_ids = tokenizer.apply_chat_template(
    messages,
    add_generation_prompt=True,
    return_tensors="pt"
).to(model.device)

terminators = [
    tokenizer.eos_token_id,
    tokenizer.convert_tokens_to_ids("<|eot_id|>")
]

outputs = model.generate(
    input_ids,
    max_new_tokens=256,
    eos_token_id=terminators,
    do_sample=True,
    temperature=0.6,
    top_p=0.9,
)
response = outputs[0][input_ids.shape[-1]:]
print(tokenizer.decode(response, skip_special_tokens=True))
