# Serving Online Inference with TGI and Medusa on Vast.ai

## Background

Medusa is a method of specular decoding. Speculative decoding speeds up inference of large language models by having a smaller model multiple tokens and lets the larger model just verify. If the Verification for the large model is cheaper than generating the tokens themselves. If the smaller model is accurate enough, then the cost to generate tokens goes down overall.

Medusa is slightly different than other types of speculative decoding in that it adds a piece of the original model to do the speculation.

TGI is the first major serving framework for large language models that enables Medusa-style speculative decoding.

Speculative decoding comes with a trade-off between adding extra memory used and generation speed. Speculative decoding, including Medusa, requires more overall memory. But if your "draft" model is good enough, then it can provide an excellent speed up opportunity.

Compared to other forms of speculative decoding, Medusa requires a fine-tuned adapter on top of the original model. There exist some of these already that we can use. Be on the lookout for more posts on how to create these adapters from us.

To set up TGI with Medusa on Vast, you can follow the steps outlined in the provided notebook. The notebook will guide you through the process of configuring TGI to serve Medusa and optimizing the setup for your specific use case.

## Setup and Querying

First, set up your environment and Vast API key:

```bash
pip install --upgrade vastai
```

Once you create your account, go [here](https://cloud.vast.ai/cli/) to find your API key.

```bash
vastai set api-key <Your-API-Key-Here>
```

For serving a language model, we're looking for a machine with a static IP address, available ports to host on, and a single modern GPU with decent RAM, as we'll serve a single small model. TGI also requires CUDA version 12.1.1 or higher, so we'll filter for that as well. We will query the Vast API to get a list of these types of machines.

```bash
vastai search offers 'compute_cap > 800 gpu_ram > 20 num_gpus = 1 static_ip=true direct_port_count > 1 cuda_vers >= 12.1.1'
```

## Deploying the Image

The easiest way to deploy this instance is to use the command line. Copy and paste a specific instance ID you choose from the list above into `instance-id` below. This medusa model also needs to download gemma-7b-it, which is a gated model. You'll need to accept the terms on gemma-7b-it and pass in your Huggingface API Token into `HF_TOKEN=<Your_Huggingface_Token>`
.

```bash
vastai create instance <instance-id> --image ghcr.io/huggingface/text-generation-inference:latest --env '-p 8000:8000 -e HF_TOKEN={"<Huggingface-Token>"}' --disk 40 --args --port 8000 --model-id text-generation-inference/gemma-7b-it-medusa --speculate 2
```

## Connecting and Testing

To connect to your instance, we'll first need to get the IP address and port number. Once your instance is done setting up, you should see something like this:
![Instance_view](/uploads/instance_view_medusa_tgi.png)

Click on the highlighted button to see the IP address and correct port for our requests.

![IP_address_view](/uploads/ip_address_view_medusa_tgi.png)

We will copy over the IP address and the port into the cell below.

```bash
# This request assumes you haven't changed the model. If you did, fill it in the "model" value in the payload json below
curl -X POST http://<IP-Address>:<Port>/v1/completions -H "Content-Type: application/json"  -d '{"model" : "text-generation-inference/gemma-7b-it-medusa", "prompt": "Hello, how are you?", "max_tokens": 50}'
```

You will see a response from your model in the output. Your model is up and running on Vast!

In the [notebook](https://nbviewer.org/urls/bitbucket.org/%21api/2.0/snippets/jsbcannell/q7gnzg/30783bfb0b148eaf67a02f083b9cf579be87c5fc/files/serving_medusa_on_vast.json), we include ways to call this model with requests or OpenAI

### Other things to look out for with other configurations

If you are downloading a model that needs authentication from the Hugging Face Hub, passing `-e HF_token=<Your-Read-Only-Token>` within Vast's `--env` variable string should help.

Sometimes the full context of a model can't be used given the space allocated for TGI on the GPU + the model's size. In those cases, you might want to increase `--gpu-memory-utilization`, or decrease the `max-model-len`. Increasing `--gpu-memory-utilization` does come with CUDA OutOfMemory issues that can be hard to predict ahead of time.

We won't need either of these for this specific model and GPU configuration.

### Testing

Copy the IP address from your instance once it is ready, and then we can use the following code to call it. Note that while your server might have ports ready, the model might not have downloaded yet as it is much larger this time. You can check the status of this via the logs to see when it has started serving.

```bash
import requests

headers = {
    'Content-Type': 'application/json',
}

json_data = {
    'model': 'text-generation-inference/gemma-7b-it-medusa',
    'prompt': 'Hello, how are you?',
    'max_tokens': 50,
}

response = requests.post('http://<Instance-IP-Address>:<Port>/v1/completions', headers=headers, json=json_data)
print(response.content)
```

Or use OpenAI:

```bash
pip install openai
```

```python
from openai import OpenAIH

# Modify OpenAI's API key and API base to use TGI's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://<Instance-IP-Address>:<Port>/v1"
client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)
completion = client.completions.create(model="text-generation-inference/gemma-7b-it-medusa",
                                      prompt="Hello, how are you?",
                                      max_tokens=50)
print("Completion result:", completion)
```

# Serving Online Inference with Text-Embeddings-Inference on Vast.ai

## Background
Text-Embeddings-Inference is an open source framework for embedding and reranker inference. It is made by Hugging Face and is focused on low latency, high throughput serving with short boot times due to a small docker image.

Embeddings and Re-rankers are often very important for many use cases like RAG, Information Retrieval, Search, and dataset cleaning + exploration. 

This guide will show you how to setup `Text-Embeddings-Inference` to serve an embedding model for online inference on Vast. We reference a notebook that you can use [here](https://nbviewer.org/urls/bitbucket.org/%21api/2.0/snippets/jsbcannell/Bzkbbr/3cb18e2bca4e49129125a322bafb38346abf6abd/files/serving_text_embeddings_inference_on_vast.json).

## Setup and Querying
First, we setup our environment and vast api key

```bash
pip install --upgrade vastai
```

Once you create your account, you can go [here](https://cloud.vast.ai/cli/) to find your API Key.

```bash
vastai set api-key <Your-API-Key-Here>
```

For serving, we're looking for a machine that has a static IP address, ports available to host on, plus a single modern GPU since we're going to serve a single small model. `Text-Embeddings-Inference` also requires Cuda version 12.2 or higher, so we will filter for that as well. We'll query the Vast API to get a list of these types of machines.

```bash
vastai search offers 'compute_cap >= 800 num_gpus = 1 static_ip=true direct_port_count > 1 cuda_vers >= 12.2' 
```

## Deploying the Image:
The easiest way to deploy this instance is to use the command line. Copy and Paste a specific instance id you choose from the list above into `instance-id` below. 

We also told `Text-Embeddings-Inference` to serve on port 8000 as that is the default port for the OpenAI SDK, but it would normally serve on port 80 instead. Feel free to change this as you like

```bash 
vastai create instance <instance-id> --image ghcr.io/huggingface/text-embeddings-inference --env '-p 8000:80' --disk 16 --args --model-id jinaai/jina-embeddings-v2-base-en
```

### Compute Architecture and Server Image Selection:
`Text-Embeddings-Inference` does offer support for multiple different GPU Types from Nvidia. However it is often best to match up the hardware you're using with the specific image to increase performance and reliability. They give you the recommended image for each GPU [here](https://github.com/huggingface/text-embeddings-inference?tab=readme-ov-file#docker-images)

## Connecting and Testing:
To connect to your instance, we'll first need to get the IP address and port number. Once your instance is done setting up, you should see something like this:
![Instance_view](/uploads/instance_view_tei.png)

Click on the highlighted button to see the IP address and correct port for our requests.

![IP_address_view](/uploads/ip_address_view_tei.png)

We will copy over the IP address and the port into the cell below.
```bash
curl <Instance-IP-Address>:<Port>/embed -X POST -d '{"inputs":"What is Deep Learning?"}' -H 'Content-Type: application/json'
```

You will see a response from your model in the output, which will be the embedding of your query. Your model is up and running on Vast!

## Connecting with the OpenAI SDK
The OpenAI SDK also allows for generating embeddings. We can use it as well with the following code.
```bash
pip install openai
```
```
from openai import OpenAI

# Modify OpenAI's API key and API base to use vLLM's's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://<Instance-IP-Address>:<Port>/v1"
client = OpenAI(
    api_key=openai_api_key,
    base_url=openai_api_base,
)
model = "jinaai/jina-embeddings-v2-base-en"
embeddings = client.embeddings.create(model=model, input="What is Deep Learning?")
print(embeddings)
```

This is great, as it helps us integrate our embeddings into applications that use the OpenAI SDK.

## Next Steps:

Embeddings and Re-Ranking are fundamental building blocks to many different ways of building AI applications. Stay Tuned as we cover these topics more in depth!
