# Using TGI CLI

You can use TGI command-line interface (CLI) to download weights, serve and quantize models, or get information on serving parameters. To install the CLI, please refer to [the installation section](./installation#install-cli).

`text-generation-server` lets you download the model with `download-weights` command like below 👇 

```bash
text-generation-server download-weights MODEL_HUB_ID
```

You can also use it to quantize models like below 👇 

```bash
text-generation-server quantize MODEL_HUB_ID OUTPUT_DIR 
```

You can use `text-generation-launcher` to serve models. 

```bash
text-generation-launcher --model-id MODEL_HUB_ID --port 8080
```

There are many options and parameters you can pass to `text-generation-launcher`. The documentation for CLI is kept minimal and intended to rely on self-generating documentation, which can be found by running 

```bash
text-generation-launcher --help
``` 

You can also find it hosted in this [Swagger UI](https://huggingface.github.io/text-generation-inference/).

Same documentation can be found for `text-generation-server`.

```bash
text-generation-server --help
```
