• Weight Precision: NVFP4
• Original Size: ~16 GB (bfloat16)
• Quantized Size: ~6 GB (nvfp4)

Usage

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

# Load base model structure
model = AutoModelForCausalLM.from_pretrained(
    "tokenlabsdotrun/Llama-3.1-8B-ModelOpt-NVFP4",
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True
)

# Load tokenizer and generate
tokenizer = AutoTokenizer.from_pretrained("tokenlabsdotrun/Llama-3.1-8B-ModelOpt-NVFP4")

inputs = tokenizer("Hello, my name is", return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=10)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
