Haven - Run LLMs on Your Own Cloud

Unlocking the Power of Large Language Models with Haven: Run LLMs on Your Own Infrastructure

In today's rapidly evolving technological landscape, large language models (LLMs) have emerged as a game-changer for businesses across industries. These powerful models, with their natural language understanding capabilities, can revolutionize how companies interact with data and extract insights. However, the challenge lies in deploying these models efficiently without compromising on privacy and control. This is where Haven, a startup founded in 2023 by Justus Mattern and Konstantin Hohr in Berlin, Germany, steps in. Haven aims to empower businesses to harness the potential of LLMs by allowing them to run these models on their own infrastructure. In this article, we'll delve into the world of Haven, exploring its founders, mission, and how it simplifies LLM deployment for businesses.

Who Are the Visionaries Behind Haven?

The journey of every startup begins with a vision, and Haven is no exception. Justus Mattern and Konstantin Hohr, the co-founders of Haven, share a remarkable story of collaboration and expertise that has led to the creation of this innovative platform.

Justus Mattern: The AI Researcher

Justus, one of the co-founders, brings a wealth of knowledge in artificial intelligence to the table. He is an AI researcher who has been immersed in the world of Large Language Models since 2020. Justus's academic journey has taken him to prestigious institutions like UC Berkeley and ETH Zürich, where he has made significant contributions to the field, publishing multiple papers at leading research conferences. His deep understanding of LLMs forms the cornerstone of Haven's technology.

Konstantin Hohr: The Software Engineering Maestro

On the other hand, Konstantin, Haven's second co-founder, is a seasoned software engineer with a proven track record. Before embarking on his university studies, Konstantin worked as a full-time software engineer at Germany's largest social networking company.

Introducing Haven: A Game-Changer in LLM Deployment

Haven's mission is clear: to simplify the deployment of Large Language Models on your own infrastructure. In an age where data privacy, control, and scalability are paramount, Haven offers a unique solution that caters to the needs of businesses looking to leverage LLMs for various applications.

The Problem: Relying on Third-Party Providers

Many companies recognize the potential of LLMs but are reluctant to rely on third-party providers. This dependence on external services not only introduces privacy concerns but also poses the risk of vendor lock-in. Furthermore, it may not align with an organization's strategy to keep sensitive data in-house.

Deploying LLMs in-house, however, presents its own set of challenges. Engineers often find themselves grappling with complex CUDA environments, the need to write and containerize efficient serving code, and the daunting task of exposing it as an API server. Scalability is another hurdle that organizations must overcome when running LLMs in-house.

Haven's Solution: The Best of Both Worlds

Haven bridges the gap between the simplicity and scalability of third-party providers and the need for data privacy and control. It accomplishes this through an innovative approach that allows users to run LLMs on their own cloud infrastructure.

How Does Haven Work?

At the core of Haven's solution lies Kubernetes, a powerful container orchestration platform. By leveraging Kubernetes, Haven ensures that deploying and managing LLMs is a straightforward process. Here's a step-by-step overview of how Haven works:

1. Upload a Service Account Key

The first step in deploying an LLM with Haven is to upload a Service Account Key. This key provides Haven with the necessary permissions to manage your cloud resources on your behalf. Under the hood, Haven sets up a Kubernetes cluster in your designated cloud environment, ensuring that your data remains secure and under your control.

2. Configure Your Deployment

With the Kubernetes cluster in place, you can now configure your LLM deployment. Haven offers a user-friendly interface that allows you to select the specific LLM model you want to use, choose the GPUs for acceleration, and configure the scaling behavior of your deployment. This level of customization ensures that Haven caters to your specific requirements, whether you're deploying a small-scale application or handling a massive workload.

3. Enjoy Your Model

Once you've completed the configuration, Haven takes care of the rest. Your Large Language Model is up and running in minutes. Haven's deployments offer lightning-fast inference, making it ideal for real-time applications. Additionally, they include advanced features like input batching, which enhances efficiency and responsiveness, enabling seamless integration with your applications.
