# Quick Tour
The easiest way of getting started is using the official Docker container. Install Docker following [their installation instructions](https://docs.docker.com/get-docker/).
## Launching TGI
Let's say you want to deploy [teknium/OpenHermes-2.5-Mistral-7B](https://huggingface.co/teknium/OpenHermes-2.5-Mistral-7B) model with TGI on an Nvidia GPU. Here is an example on how to do that:
```bash
model=teknium/OpenHermes-2.5-Mistral-7B
volume=$PWD/data # share a volume with the Docker container to avoid downloading weights every run
docker run --gpus all --shm-size 1g -p 8080:80 -v $volume:/data \
ghcr.io/huggingface/text-generation-inference:2.4.1 \
--model-id $model
```
<Tip>
If you want to serve gated or private models, please refer to
[this guide](https://huggingface.co/docs/text-generation-inference/en/basic_tutorials/gated_model_access)
for detailed instructions.
</Tip>
### Supported hardware
TGI supports various hardware. Make sure to check the [Using TGI with Nvidia GPUs](./installation_nvidia), [Using TGI with AMD GPUs](./installation_amd), [Using TGI with Intel GPUs](./installation_intel), [Using TGI with Gaudi](./installation_gaudi), [Using TGI with Inferentia](./installation_inferentia) guides depending on which hardware you would like to deploy TGI on.
## Consuming TGI
Once TGI is running, you can use the `generate` endpoint or the Open AI Chat Completion API compatible [Messages API](https://huggingface.co/docs/text-generation-inference/en/messages_api) by doing requests. To learn more about how to query the endpoints, check the [Consuming TGI](./basic_tutorials/consuming_tgi) section, where we show examples with utility libraries and UIs. Below you can see a simple snippet to query the endpoint.
<inferencesnippet>
<python>
```python
import requests
headers = {
"Content-Type": "application/json",
}
data = {
'inputs': 'What is Deep Learning?',
'parameters': {
'max_new_tokens': 20,
},
}
response = requests.post('http://127.0.0.1:8080/generate', headers=headers, json=data)
print(response.json())
# {'generated_text': '\n\nDeep Learning is a subset of Machine Learning that is concerned with the development of algorithms that can'}
```
</python>
<js>
```js
async function query() {
const response = await fetch(
'http://127.0.0.1:8080/generate',
{
method: 'POST',
headers: { 'Content-Type': 'application/json'},
body: JSON.stringify({
'inputs': 'What is Deep Learning?',
'parameters': {
'max_new_tokens': 20
}
})
}
);
}
query().then((response) => {
console.log(JSON.stringify(response));
});
/// {"generated_text":"\n\nDeep Learning is a subset of Machine Learning that is concerned with the development of algorithms that can"}
```
</js>
<curl>
```curl
curl 127.0.0.1:8080/generate \
-X POST \
-d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":20}}' \
-H 'Content-Type: application/json'
```
</curl>
</inferencesnippet>
<Tip>
To see all possible deploy flags and options, you can use the `--help` flag. It's possible to configure the number of shards, quantization, generation parameters, and more.
```bash
docker run ghcr.io/huggingface/text-generation-inference:2.4.1 --help
```
