GPUStack

GPUStack is an open-source GPU cluster manager for running large language models(LLMs).

Key Features

Supports a Wide Variety of Hardware: Run with different brands of GPUs in Apple MacBooks, Windows PCs, and Linux servers.
Scales with Your GPU Inventory: Easily add more GPUs or nodes to scale up your operations.
Lightweight Python Package: Minimal dependencies and operational overhead.
OpenAI-compatible APIs: Serve APIs that are compatible with OpenAI standards.
User and API key management: Simplified management of users and API keys.
GPU metrics monitoring: Monitor GPU performance and utilization in real-time.
Token usage and rate metrics: Track token usage and manage rate limits effectively.

Installation

Linux or MacOS

GPUStack provides a script to install it as a service on systemd or launchd based systems. To install GPUStack using this method, just run:

curl -sfL https://get.gpustack.ai | sh -s -

Optionally, you can add extra workers to form a GPUStack cluster by running the following command on other nodes (replace http://myserver and mytoken with your actual server URL and token):

curl -sfL https://get.gpustack.ai | sh -s - --server-url http://myserver --token mytoken

In the default setup, you can run the following to get the token used for adding workers:

cat /var/lib/gpustack/token

Windows

Run PowerShell as administrator, then run the following command to install GPUStack:

Invoke-Expression (Invoke-WebRequest -Uri "https://get.gpustack.ai" -UseBasicParsing).Content

Optionally, you can add extra workers to form a GPUStack cluster by running the following command on other nodes (replace http://myserver and mytoken with your actual server URL and token):

Invoke-Expression "& { $((Invoke-WebRequest -Uri 'https://get.gpustack.ai' -UseBasicParsing).Content) } -server-url http://myserver -token mytoken"

In the default setup, you can run the following to get the token used for adding workers:

Get-Content -Path "$env:APPDATA\gpustack\token" -Raw

Manual Installation

For manual installation or detailed configurations, refer to the installation docs.

Getting Started

Run and chat with the llama3 model:

gpustack chat llama3 "tell me a joke."

Open http://myserver in the browser to access the GPUStack UI. Log in to GPUStack with username admin and the default password. You can run the following command to get the password for the default setup:

Linux or MacOS

cat /var/lib/gpustack/initial_admin_password

Windows

Get-Content -Path "$env:APPDATA\gpustack\initial_admin_password" -Raw

Click Playground in the navigation menus. Now you can chat with the LLM in the UI playground.

Click API Keys in the navigation menus, then click the New API Key button.
Fill in the Name and click the Save button.
Copy the generated API key and save it somewhere safe. Please note that you can only see it once on creation.
Now you can use the API key to access the OpenAI-compatible API. For example, use curl as the following:

export GPUSTACK_API_KEY=myapikey
curl http://myserver/v1-openai/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $GPUSTACK_API_KEY" \
  -d '{
    "model": "llama3",
    "messages": [
      {
        "role": "system",
        "content": "You are a helpful assistant."
      },
      {
        "role": "user",
        "content": "Hello!"
      }
    ],
    "stream": true
  }'

Supported Platforms

MacOS
Linux
Windows

Supported Accelerators

Apple Metal
NVIDIA CUDA

We plan to support the following accelerators in future releases.

AMD ROCm
Intel oneAPI
Qualcomm AI Engine

Supported Models

GPUStack uses llama.cpp as the backend and supports large language models in GGUF format. Models from the following sources are supported:

Here are some example models:

OpenAI-Compatible APIs

GPUStack serves the following OpenAI compatible APIs under the /v1-openai path:

List models
Chat completions

For example, you can use the official OpenAI Python API library to consume the APIs:

from openai import OpenAI
client = OpenAI(base_url="http://myserver/v1-openai", api_key="myapikey")

completion = client.chat.completions.create(
  model="llama3",
  messages=[
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello!"}
  ]
)

print(completion.choices[0].message)

GPUStack users can generate their own API keys in the UI.
