Kalavai aggregates and coordinates spare GPU capacity

Kalavai is an open source platform that unlocks computing from spare capacity. It aggregates resources from multiple sources to increase your computing budget and run large AI workloads.

Core features

Kalavai helps teams use GPU resources more efficiently. It acts as a control plane for all your GPUs, wherever they are: local, on prem and multi-cloud.

• Increase GPU utilisation from your devices (fractional GPU).
• Multi-node, multi-GPU and multi-architecture support (AMD and NVIDIA).
• Aggregate computing resources from multiple sources: home desktops, on premise servers<0>, multi cloud VMs, raspberry pi's, etc. Including our own GPU fleets.
• Ready-made templates to deploy common AI building blocks: model inference (vLLM, llama.cpp, SGLang), GPU clusters (Ray, GPUStack), automation workflows (n8n and Flowise), evaluation and monitoring tools (Langfuse), production dev tools (LiteLLM, OpenWebUI) and more.
• Easy to expand to custom workloads

• n8n (experimental): no-code workload automation framework.
• Flowise (experimental): no-code agentic AI workload framework.
• Speaches: audio (speech-to-text and text-to-speech) model inference.
• Langfuse (experimental): open source evaluation and monitoring GenAI framework.
• OpenWebUI: ChatGPT-like UI playground to interface with any models.
• diffusers (experimental)
• RayServe inference.
• GPUstack (experimental)

Kalavai is at an early stage of its development. We encourage people to use it and give us feedback! Although we are trying to minimise breaking changes, these may occur until we have a stable version (v1.0).

Getting started

The kalavai-client is the main tool to interact with the Kalavai platform, to create and manage GPU pools and also to interact with them (e.g. deploy models). A pool consists of:

• A seed node(s): one (or more for high availability deployments) machine that acts as central control plane
• One or many worker nodes: any machine connected to the seed node that can carry out workloads (generally with access to a GPU)

Requirements

For seed nodes:

• A 64 bits x86 based Linux machine (laptop, desktop or VM)
• Docker engine installed with privilege access.

For workers sharing resources with the pool:

• A laptop, desktop or Virtual Machine. Full support: Linux and Windows; x86 architecture. Limited support: Mac and ARM architecture.
• If self-hosting, workers should be on the same network as the seed node. Looking for over-the-internet connectivity? Check out our managed seeds
• Docker engine installed (for linux, Windows and MacOS) with privilege access.

Compatibility matrix

If your system is not currently supported, open an issue and request it. We are expanding this list constantly.

Install the client

The client is a python package and can be installed with one command:

pip install kalavai-client

Create a a local private pool

For a quick start, get a pool going with:

kalavai pool start

And then start the GUI:

kalavai gui start

This will expose the GUI and the backend services in localhost. By default, the GUI is accessible via http://localhost:49153.

Check out our getting started guide for next steps on how to add more workers to your pool, or use our managed platform for over-the-internet AI pools.

Enough already, let's run stuff!

Check out our use cases documentation for inspiration on what you can do with Kalavai:

• Multi-GPU LLM
• Fine tune
• BYO Model Gateway
• Easy LLMs with GPUstack
• Production GPU fleets
