### Connect to a Llama Stack Together Endpoint
- You may connect to a hosted endpoint `https://llama-stack.together.ai`, serving a Llama Stack distribution
### Start a Together distribution
```
```
# TGI Distribution
The `llamastack/distribution-tgi` distribution consists of the following provider configurations.
The `llamastack/distribution-together` distribution consists of the following provider configurations.
| **API** | **Inference** | **Agents** | **Memory** | **Safety** | **Telemetry** |
|----------------- |--------------- |---------------- |-------------------------------------------------- |---------------- |---------------- |
| **Provider(s)** | remote::tgi | meta-reference | meta-reference, remote::pgvector, remote::chroma | meta-reference | meta-reference |
| **Provider(s)** | remote::together | meta-reference | remote::weaviate | meta-reference | meta-reference |
### Start the Distribution (Single Node GPU)
> [!NOTE]
> This assumes you have access to GPU to start a TGI server with access to your GPU.
```
$ cd llama_stack/distribution/docker/tgi
$ ls
compose.yaml tgi-run.yaml
$ docker compose up
```
The script will first start up TGI server, then start up Llama Stack distribution server hooking up to the remote TGI provider for inference. You should be able to see the following outputs --
```

### (Alternative) TGI server + llama stack run (Single Node GPU)
If you wish to separately spin up a TGI server, and connect with Llama Stack, you may use the following commands.
#### (optional) Start TGI server locally
- Please check the [TGI Getting Started Guide](https://github.com/huggingface/text-generation-inference?tab=readme-ov-file#get-started) to get a TGI endpoint.
```
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-3.1-8B-Instruct --port 5009
```
#### Start Llama Stack server pointing to TGI server
```
docker run --network host -it -p 5000:5000 -v ./run.yaml:/root/my-run.yaml --gpus=all llamastack-local-cpu --yaml_config /root/my-run.yaml
docker run --network host -it -p 5000:5000 -v ./run.yaml:/root/my-run.yaml --gpus=all llamastack/distribution-together --yaml_config /root/my-run.yaml
```
Make sure in you `run.yaml` file, you inference provider is pointing to the correct Together URL server endpoint. E.g.
