Meta-Llama-3-8B-Instruct is an instruct-tuned decoder-only, text-to-text model. The instruction-tuning uses supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to align with human preferences for helpfulness and safety.

Model Description
Meta-Llama-3-8B-Instruct is an instruct-tuned decoder-only, text-to-text model. It was trained on 15 trillion tokens of data from publicly available sources. The instruction-tuning uses supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to align with human preferences for helpfulness and safety.
Meta-Llama-3-8B-Instruct builds on the existing work done for the Llama, and Llama 2, family of models. It makes a few key improvements:
- 128K token vocabulary, allowing for language to be encoded more efficiently
- Grouped-Query Attention (GQA) for all sizes of the model
- 8,192 context window for training with cross-document masking
In their development of these models, Meta took great care to optimize for helpfulness and safety.
More details on the model can be found here.
This model is optimized through NVIDIA NeMo Framework, and is provided through a .nemo checkpoint.
Getting Started
Step 1: Fetching the model file
- You can download the model from NGC using the CLI tool.
ngc registry model download-version nvidia/nemo/llama-3-8b-instruct-nemo:1.0
- (Optional, Recommended) Pre-extract the model from the
.nemofile. This will reduce the model loading time overhead because the NeMo scripts will not have to extract the model from the .nemo everytime they are run. This step is not required though, and NeMo scripts can still ingest the.nemofile directly as well.
mkdir llama_3_8B_instruct
tar -xvf 8b_instruct_nemo_bf16.nemo -C llama_3_8B_instruct
You can find the instructions to install and configure the NGC CLI tool here
Step 2: Fetch the NeMo Framework container
You can use the NeMo Framework container available on NGC which comes preloaded with all the required dependencies.
export NEMO_IMAGE="nvcr.io/nvidia/nemo:24.05"
docker pull $NEMO_IMAGE
Step 3: Run the NeMo container
Run the NeMo framework container, mounting the model.
# Full path to the extracted model directory
export MODEL_DIR=$(pwd)/llama_3_8B_instruct
docker run --gpus all -it --rm -v ${MODEL_DIR}:/model $NEMO_IMAGE
Step 4: Follow The Desired Playbooks (Coming Soon!)
We're hard at work preparing resources to enable you to most easily use the Meta-Llama-3-8B-Instruct .nemo checkpoint!
