This will download and start running a pre-built Docker container. Alternatively, you may use the following commands:
```
docker run -it -p 5000:5000 -v ~/.llama:/root/.llama -v ./run.yaml:/root/my-run.yaml --gpus=all distribution-meta-reference-gpu --yaml_config /root/my-run.yaml

The script will first start up vLLM server on port 8000, then start up Llama Stack distribution server hooking up to it for inference. You should see the following outputs --

**(Option 2) Via Conda**
::::{tab-set}
:::{tab-item} meta-reference-gpu
1. Install the `llama` CLI. See [CLI Reference](https://llama-stack.readthedocs.io/en/latest/cli_reference/index.html)
2. Build the `meta-reference-gpu` distribution
```
$ llama stack build --template meta-reference-gpu --image-type conda
```
3. Start running distribution
```
$ llama stack run ~/.llama/distributions/llamastack-meta-reference-gpu/meta-reference-gpu-run.yaml
```
Note: If you wish to use pgvector or chromadb as memory provider. You may need to update generated `run.yaml` file to point to the desired memory provider. See [Memory Providers](https://llama-stack.readthedocs.io/en/latest/api_providers/memory_api.html) for more details. Or comment out the pgvector or chromadb memory provider in `run.yaml` file to use the default inline memory provider, keeping only the following section:
```
memory:

provider_type: faiss
config:
kvstore:
namespace: null
type: sqlite
db_path: ~/.llama/runtime/faiss_store.db

```
3. Start a TGI server endpoint
4. Make sure in your `run.yaml` file, your `conda_env` is pointing to the conda environment and inference provider is pointing to the correct TGI server endpoint. E.g.

[Start Ollama Distribution](https://llama-stack.readthedocs.io/en/latest/getting_started/distributions/self_hosted_distro/ollama.html)
If you wish to separately spin up a Ollama server, and connect with Llama Stack, you may use the following commands.
#### Start Ollama server.
- Please check the [Ollama Documentations](https://github.com/ollama/ollama) for more details.
**Via Docker**
```
docker run -d -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama
```
**Via CLI**
```
ollama run <model_id>
```
#### Start Llama Stack server pointing to Ollama server
Make sure your `run.yaml` file has the inference provider pointing to the correct Ollama endpoint. E.g.
```
conda_env: llamastack-ollama
...
inference:
- provider_id: ollama0
provider_type: remote::ollama

##### 1.2 (Optional) Update Model Serving Configuration
::::{tab-set}
:::{tab-item} meta-reference-gpu
You may change the `config.model` in `run.yaml` to update the model currently being served by the distribution. Make sure you have the model checkpoint downloaded in your `~/.llama`.
```
inference:
- provider_id: meta0
provider_type: inline::meta-reference
config:
model: Llama3.2-11B-Vision-Instruct
quantization: null
torch_seed: null
max_seq_len: 4096
max_batch_size: 1
```
Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.
:::
:::{tab-item} tgi
To serve a new model with `tgi`, change the docker command flag `--model-id <model-to-serve>`.
This can be done by edit the `command` args in `compose.yaml`. E.g. Replace "Llama-3.2-1B-Instruct" with the model you want to serve.
```
command: ["--dtype", "bfloat16", "--usage-stats", "on", "--sharded", "false", "--model-id", "meta-llama/Llama-3.2-1B-Instruct", "--port", "5009", "--cuda-memory-fraction", "0.3"]
```
or by changing the docker run command's `--model-id` flag
```
docker run --rm -it -v $HOME/.cache/huggingface:/data -p 5009:5009 --gpus all ghcr.io/huggingface/text-generation-inference:latest --dtype bfloat16 --usage-stats on --sharded false --model-id meta-llama/Llama-3.2-1B-Instruct --port 5009
```
Make sure your `run.yaml` file has the inference provider pointing to the TGI server endpoint serving your model.
```
inference:
- provider_id: tgi0
provider_type: remote::tgi
config:
url: http://127.0.0.1:5009
```
```
Run `llama model list` to see the available models to download, and `llama model download` to download the checkpoints.
:::
:::{tab-item} ollama
You can use ollama for managing model downloads.
```
ollama pull llama3.1:8b-instruct-fp16
ollama pull llama3.1:70b-instruct-fp16
```
> Please check the [OLLAMA_SUPPORTED_MODELS](https://github.com/meta-llama/llama-stack/blob/main/llama_stack/providers.remote/inference/ollama/ollama.py) for the supported Ollama models.
To serve a new model with `ollama`
```
ollama run <model_name>
```
To make sure that the model is being served correctly, run `ollama ps` to get a list of models being served by ollama.
```
$ ollama ps
NAME ID SIZE PROCESSOR UNTIL
llama3.1:8b-instruct-fp16 4aacac419454 17 GB 100% GPU 4 minutes from now
```
To verify that the model served by ollama is correctly connected to Llama Stack server
```
