Meta Reference GPU Distribution

:maxdepth: 2
:hidden:

self

The llamastack/distribution-meta-reference-gpu distribution consists of the following provider configurations:

API	Provider(s)
agents	inline::meta-reference
datasetio	remote::huggingface, inline::localfs
eval	inline::meta-reference
inference	inline::meta-reference
safety	inline::llama-guard
scoring	inline::basic, inline::llm-as-judge, inline::braintrust
tool_runtime	remote::brave-search, remote::tavily-search, inline::rag-runtime, remote::model-context-protocol
vector_io	inline::faiss, remote::chromadb, remote::pgvector

Note that you need access to nvidia GPUs to run this distribution. This distribution is not compatible with CPU-only machines or machines with AMD GPUs.

Environment Variables

The following environment variables can be configured:

• LLAMA_STACK_PORT: Port for the Llama Stack distribution server (default: 8321)
• INFERENCE_MODEL: Inference model loaded into the Meta Reference server (default: meta-llama/Llama-3.2-3B-Instruct)
• INFERENCE_CHECKPOINT_DIR: Directory containing the Meta Reference model checkpoint (default: null)
• SAFETY_MODEL: Name of the safety (Llama-Guard) model to use (default: meta-llama/Llama-Guard-3-1B)
• SAFETY_CHECKPOINT_DIR: Directory containing the Llama-Guard model checkpoint (default: null)

Prerequisite: Downloading Models

Please check that you have llama model checkpoints downloaded in ~/.llama before proceeding. See installation guide here to download the models using the Hugging Face CLI.

## Running the Distribution

You can do this via venv or Docker which has a pre-built image.

### Via Docker

This method allows you to get started quickly without having to build the distribution code.

```bash
LLAMA_STACK_PORT=8321
docker run \
  -it \
  --pull always \
  --gpu all \
  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
  -v ~/.llama:/root/.llama \
  -e INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
  llamastack/distribution-meta-reference-gpu \
  --port $LLAMA_STACK_PORT

If you are using Llama Stack Safety / Shield APIs, use:

docker run \
  -it \
  --pull always \
  --gpu all \
  -p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
  -v ~/.llama:/root/.llama \
  -e INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
  -e SAFETY_MODEL=meta-llama/Llama-Guard-3-1B \
  llamastack/distribution-meta-reference-gpu \
  --port $LLAMA_STACK_PORT

Via venv

Make sure you have the Llama Stack CLI available.

llama stack list-deps meta-reference-gpu | xargs -L1 uv pip install
INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
llama stack run distributions/meta-reference-gpu/run.yaml \
  --port 8321

If you are using Llama Stack Safety / Shield APIs, use:

INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct \
SAFETY_MODEL=meta-llama/Llama-Guard-3-1B \
llama stack run distributions/meta-reference-gpu/run-with-safety.yaml \
  --port 8321
