How This Startup Is Betting on Small, In-House AI Models Over OpenAI's API Amid Tech Companies' Experiments

ZenML aims to serve as the central connector for various open-source AI tools. This innovative open-source framework allows data scientists, machine-learning engineers, and platform engineers to seamlessly collaborate and develop new AI models.

What makes ZenML particularly noteworthy is its ability to empower companies to create private AI models tailored to their specific needs. While it's unlikely that businesses will produce a competitor to GPT-4, they can indeed develop smaller, specialized models that address their unique challenges. This approach will significantly reduce their reliance on external API providers like OpenAI and Anthropic.

"The vision is that once the current wave of excitement surrounding proprietary APIs like OpenAI subsides, ZenML will enable companies to build their own integrated AI stack," explained Louis Coppey, a partner at the VC firm Point Nine. Earlier this year, ZenML successfully secured an extension of its seed funding from Point Nine, with the participation of existing investor Crane. Since its inception in Munich, Germany, ZenML has raised a total of $6.4 million.

Co-founders Adam Probst and Hamza Tahir have a history of working together on machine learning (ML) pipelines for specific industries. "Every day, we faced the challenge of developing machine learning models and deploying them into production," noted ZenML's CEO, Adam Probst. This experience led them to create a modular system designed to adapt to varying conditions and customers, eliminating the need for repetitive tasks.

Additionally, ZenML's modular system helps engineers embarking on their machine learning journey to gain a head start. This space is known as MLOps—akin to DevOps, but specifically tailored for machine learning applications.

“We are linking various open-source tools that focus on specific stages of the ML pipeline, utilizing both hyperscaler infrastructure like AWS and Google Cloud as well as on-premise solutions,” Probst said.

The core of ZenML's functionality lies in its pipelines. Users can write a pipeline that can be executed locally or deployed via open-source tools such as Airflow or Kubeflow. Furthermore, it is compatible with managed cloud services like EC2, Vertex Pipelines, and SageMaker, while also integrating with open-source ML frameworks from Hugging Face, MLflow, TensorFlow, PyTorch, and more.

"ZenML acts as a unifying platform that consolidates various tools into a cohesive experience—it accommodates multiple vendors and cloud providers," stated ZenML CTO Hamza Tahir. The framework enhances ML workflows through integrated connectors, observability, and audit functionality.

Initially released on GitHub as an open-source tool, ZenML has garnered over 3,000 stars on the platform. The company has also introduced a cloud version featuring managed servers, with triggers for continuous integrations and deployments (CI/CD) set to roll out soon. Organizations have begun utilizing ZenML for applications in industrial sectors, e-commerce recommendation systems, and image recognition in healthcare, with notable clients including Rivian, Playtika, and Leroy Merlin.

The future of ZenML depends significantly on the evolution of the AI landscape. Currently, many companies are integrating AI features into their products by leveraging OpenAI's APIs—offering capabilities like text summarization and automated customer support responses.

"While OpenAI will continue to play a role, we believe the majority of the market will need to adopt its own tailored solutions," Probst asserted.

However, there are challenges with these APIs—they tend to be overly complex and costly. "OpenAI and other large language models are designed for general use but can be too advanced and expensive for specialized applications," Probst elaborated.

OpenAI’s CEO, Sam Altman, also acknowledges the necessity for a diverse approach within AI, asserting, "It’s likely a hybrid model will emerge, both for specialized models and broader solutions."

Moreover, ethical and regulatory considerations surrounding AI are rapidly evolving. As regulations progress, particularly in Europe, there may be greater incentive for companies to leverage AI models trained on specific datasets tailored to their needs.

"Gartner predicts that 75% of enterprises will transition from proofs of concept to production in 2024. This next year or two could represent pivotal moments in AI history as we move toward deploying a mix of open-source foundational models refined on proprietary data," Tahir shared.

"The essence of MLOps lies in our belief that 99% of AI applications will be powered by more specialized, cost-effective, and smaller models developed in-house," he added, highlighting ZenML's transformative potential.
