**SuperLaser** provides a comprehensive suite of tools and scripts designed for deploying Large Language Models (LLMs) onto [RunPod's](https://github.com/runpod) pod and serverless infrastructure. Additionally, the deployment utilizes a containerized [vLLM](https://github.com/vllm-project/vllm) engine during runtime, ensuring memory-efficient and high-performance inference capabilities.

- **Scalable Deployment**: Easily scale your LLM inference tasks with vLLM and RunPod serverless capabilities.
- **Cost-Effective**: Optimize resource and hardware usage: tensor parallelism and other GPU assets.
- **Uses OpenAI's API**: Use the SuperLaser client for with chat, non-chat, and streaming options.

# Install <img align="center" width="30" height="29" src="https://media.giphy.com/media/sULKEgDMX8LcI/giphy.gif">

```bash
pip install superlaser
```
Before you begin, ensure you have:

- A RunPod account.
# RunPod Config <img align="right" width="75" height="75" src="./img/runpod-logo.png">

First step is to obtain an API key from RunPod. Go to your account's console, in the `Settings` section, click on `API Keys`.

After obtaining a key, set it as an environment variable:

```bash
export RUNPOD_API_KEY=<YOUR-API-KEY>
```
### Configure Template

Before spinning up a serverless endpoint, let's first configure a template that we'll pass into the endpoint during staging. The template allows you to select a serverless or pod asset, your docker image name, and the container's and volume's disk space.

Configure your template with the following attributes:

```py
import os
from superlaser import RunpodHandler as runpod

api_key = os.environ.get("RUNPOD_API_KEY")

template_data = runpod.set_template(
    serverless="true",                                      # false spins up a pod instead
    template_name="superlaser-inf",                         # Give a name to your template
    container_image="runpod/worker-vllm:0.3.1-cuda12.1.0",  # Docker image stub
    model_name="mistralai/Mistral-7B-v0.1",                 # Hugging Face model stub
    max_model_length=340,                                   # Maximum number of tokens for the engine to handle per request.
    container_disk=15,                                      
    volume_disk=15,
)
```
### Create Template on RunPod

```py
template = runpod(api_key, data=template_data)
print(template().text)
```
### Configure Endpoint

After your template is created, it will return a data dicitionary that includes your template ID. We will pass this template id when configuring the serverless endpoint in the section below:

```py
endpoint_data = runpod.set_endpoint(
    gpu_ids="AMPERE_24", # options for gpuIds are "AMPERE_16,AMPERE_24,AMPERE_48,AMPERE_80,ADA_24"
    idle_timeout=5,
    name="vllm_endpoint",
    scaler_type="QUEUE_DELAY",
    scaler_value=1,
    template_id="template-id",
    workers_max=1,
    workers_min=0,
)
```

### Start Endpoint on RunPod

```py
endpoint = runpod(api_key, data=endpoint_data)
print(endpoint().text)
```

# Call Endpoint <img align="right" width="225" height="75" src="./img/vllm-logo.png">

After your endpoint is staged, it will return a dictionary with your endpoint ID. Pass this endpoint ID to the `OpenAI` client and start making API requests!

```py
from openai import OpenAI

endpoint_id = "you-endpoint-id"

client = OpenAI(
    api_key=api_key,
    base_url=f"https://api.runpod.ai/v2/{endpoint_id}/openai/v1",
)
```

#### Chat w/ Streaming

```py
stream = client.chat.completions.create(
    model="mistralai/Mistral-7B-Instruct-v0.1",
    messages=[{"role": "user", "content": "To be or not to be"}],
    temperature=0,
    max_tokens=100,
    stream=True,
)

for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="", flush=True)
```

#### Completion w/ Streaming

```py
stream = client.completions.create(
    model="meta-llama/Llama-2-7b-hf",
    prompt="To be or not to be",
    temperature=0,
    max_tokens=100,
    stream=True,
)

for response in stream:
    print(response.choices[0].text or "", end="", flush=True)
```
