Beta9

Beta9 is an open-source platform for running scalable serverless GPU workloads across cloud providers.

Features:

• Scale out workloads to thousands of GPU (or CPU) containers
• Ultrafast cold-start for custom ML models
• Automatic scale to zero so you pay for only what you use
• Flexible distributed storage for storing models and function outputs
• Distribute workloads across multiple cloud providers
• Easily deploy task queues and functions using simple Python abstractions

We use beta9 internally at Beam to run AI applications for users at scale.

Use-Cases

Serverless Inference Endpoints

Decorate Any Python Function

from beta9 import Image, endpoint


@endpoint(
    cpu=1,
    memory="16Gi",
    gpu="T4",
    image=Image(
        python_packages=[
            "vllm==0.4.1",
        ],  # These dependencies will be installed in your remote container
    ),
)
def predict():
    from vllm import LLM

    prompts = ["The future of AI is"]
    llm = LLM(model="facebook/opt-125m")
    output = llm.generate(prompts)[0]

    return {"prediction": output.outputs[0].text}

Deploy It to the Cloud

$ beta9 deploy app.py:predict --name llm-inference

-H 'Authorization: Bearer [YOUR_AUTH_TOKEN]' \
-d '{}'

Fan-Out Workloads to Hundreds of Containers

from beta9 import function

# This decorator allows you to parallelize this function
# across multiple remote containers
@function(cpu=1, memory=128)
def square(i: int):
    return i**2


def main():
    numbers = list(range(100))
    squared = []

    # Run a remote container for every item in list
    for result in square.map(numbers):
        squared.append(result)

Enqueue Async Jobs

from beta9 import task_queue, Image


@task_queue(
    cpu=1.0,
    memory=128,
    gpu="T4",
    image=Image(python_packages=["torch"]),
    keep_warm_seconds=1000,
)
def multiply(x):
    result = x * 2
    return {"result": result}

# Manually insert task into the queue
multiply.put(x=10)

How It Works

Beta9 is designed for launching remote serverless containers quickly. There are a few things that make this possible:

• A custom, lazy loading image format (CLIP) backed by S3/FUSE
• A fast, redis-based container scheduling engine
• Content-addressed storage for caching images and files
• A custom runc container runtime

Get Started

Beam Cloud (Recommended)

The fastest and most reliable way to get started is by signing up for our managed service, Beam Cloud. Your first 10 hours of usage are free, and afterwards you pay based on usage.

Open-Source Deploy (Advanced)

You can run Beta9 locally, or in an existing Kubernetes cluster using our Helm chart.

Local Development

Setting Up the Server

k3d is used for local development. You'll need Docker and Make to get started.

To use our fully automated setup, run the setup make target.

Note

This will overwrite some of the tools you may already have installed. Review the setup.sh to learn more.

make setup

Setting Up the SDK

The SDK is written in Python. You'll need Python 3.8 or higher. Use the setup-sdk make target to get started.

Note

This will install the Poetry package manager.

make setup-sdk

Using the SDK

After you've setup the server and SDK, check out the SDK readme here.
