Minitron 8B Base

Minitron is a family of small language models (SLMs) obtained by pruning NVIDIA's Nemotron-4 15B model. We prune model embedding size, attention heads, and MLP intermediate dimension, following which, we perform continued training with distillation to arrive at the final models.

Deriving the Minitron 8B and 4B models from the base 15B model using our approach requires up to 40x fewer training tokens per model compared to training from scratch; this results in compute cost savings of 1.8x for training the full model family (15B, 8B, and 4B). Minitron models exhibit up to a 16% improvement in MMLU scores compared to training from scratch, perform comparably to other community models such as Mistral 7B, Gemma 7B and Llama-3 8B, and outperform state-of-the-art compression techniques from the literature. Please refer to our arXiv paper for more details.

Minitron models are for research and development only.

HuggingFace Quickstart

The PR to support our models in Hugging Face in under review and expected to be merged soon. In the meantime, this branch at commit ID 63d9cb0 can be used for Minitron models:

git clone [email protected]:suiyoubi/transformers.git
cd transformers
git checkout 63d9cb0
pip install .

The following code provides an example of how to load the Minitron-8B model and use it to perform text generation.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

# Load the tokenizer and model
model_path = "nvidia/Minitron-8B-Base"
tokenizer = AutoTokenizer.from_pretrained(model_path)

device='cuda'
dtype=torch.bfloat16
model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype=dtype, device_map=device)

# Prepare the input text
prompt = "To be or not to be,"
input_ids = tokenizer.encode(prompt, return_tensors="pt").to(model.device)

# Generate the output
output_ids = model.generate(input_ids, max_length=50, num_return_sequences=1)

# Decode and print the output
output_text = tokenizer.decode(output_ids[0], skip_special_tokens=True)
print(output_text)
