BRUSSELS, October 28, 2025 (GLOBE NEWSWIRE) — Eclipse Foundationone of the world's largest open source software foundations, today announced the introduction of Agent Definition Language (ADL) functionality into LMOS Eclipse (Operating system language models).
Eclipse LMOS is an open source platform for managing intelligent AI agents that perform complex tasks at enterprise scale. It consists of three main components:
- Eclipse LMOS ADL (Agent Definition Language): A structured, model-neutral language and set of visual tools that allows domain experts to reliably define agent behavior and collaborate seamlessly with engineers.
- Eclipse LMOS ARC Agent Platform: Native JVM infrastructure with Kotlin runtime for developing, testing and extending AI agents comes with a built-in visual interface for fast iteration and debugging.
- Eclipse LMOS Platform: An open, vendor-neutral orchestration layer for agent lifecycle management, discovery, semantic routing, and observability, built on the CNCF stack and currently in alpha.
As an industry-first innovation, ADL eliminates the complexities of traditional operational design by providing a structured, model-agnostic framework that allows business and engineering teams to collaboratively define agent behavior in a consistent, maintainable, and versionable way. This common language improves the reliability and scalability of growing agent use cases, allowing enterprises to design and manage complex agent systems with confidence. This capability further differentiates Eclipse LMOS from proprietary alternatives.
The goal of the LMOS project is to create an independent, open platform on which AI agents can be developed, deployed, and seamlessly integrated into networks and ecosystems. Built on open standards such as Kubernetes, LMOS is already in production with one of the largest enterprise deployments of agent-based AI in Europe.
“Agentic AI is redefining enterprise software, but until now there have been no open source alternatives to proprietary offerings,” said Mike Milinkovic, executive director of the Eclipse Foundation. “With Eclipse LMOS and ADL, we provide a powerful, open platform that any organization can use to build scalable, intelligent, and transparent agent systems.”
Empowering enterprises to build the future of agent-based artificial intelligence
Agentic AI represents a generational shift in the way enterprises approach the use of their technology stack. According to Gartner (June 2025)by 2028, 15% of daily business decisions will be made autonomously using agent-based AI, and 33% of enterprise applications will include such capabilities, up from less than 1% in 2024.
Eclipse LMOS is uniquely designed to enable enterprise IT teams to leverage existing DevOps infrastructure, skills, and practices. Powered by technologies such as Kubernetes, Istio, and JVM-based applications, LMOS integrates naturally into enterprise environments, accelerating adoption while protecting previous investments.
ADL implementation builds on this foundation by empowering non-technical users to shape agent behavior. Business experts, not just engineers, can directly encode requirements into agents, accelerating time to market and ensuring that agent behavior accurately reflects real-world domain knowledge.
“With ADL, we wanted to make defining agent behavior as intuitive as describing a business process, while maintaining the rigor that engineers expect,” said Arun Joseph, Eclipse LMOS project manager. “This removes the fragility of operational design and gives enterprises a practical path to scaling agent-based AI using existing teams and resources.”
Together these two pillars, leverage existing engineering investments and empower business experts with ADLwill make LMOS unique among agent AI platforms.
Enterprise Benefits
Compared to proprietary solutions, Eclipse LMOS provides:
- Open architecture – Innovation thrives in an open environment. LMOS is part of an open ecosystem that invites developers, data scientists and organizations to collaborate and shape the future of multi-agent systems.
- Cooperation – AI agent collaboration improves problem solving. LMOS orchestrates these interactions through advanced routing based on user intent or goals, allowing agents to work seamlessly together as part of a single, unified system.
- Cloud scalability – As your AI needs grow, LMOS grows with you. Its cloud-based architecture dynamically scales from a few agents to hundreds, ensuring seamless operation as your AI operations scale.
- Modularity – LMOS is built on a modular basis, making it easy to integrate new agents into your preferred development language or framework.
- Extensibility – Extensibility drives innovation. LMOS defines clear specifications that allow it to rapidly expand its ecosystem.
- Ability to work with multiple tenants “Designed with enterprise in mind, LMOS is multi-user-ready from the start. LMOS enables efficient management of multiple tenants and groups of agents within a single infrastructure.
Real impact
At Deutsche Telekom Eclipse LMOS powers the award-winning Fragment of purple OneBOT assistant and other artificial intelligence systems that work with clients. This is the deployment one of Europe's largest multi-agent enterprise deploymentsprocessed millions of service and sales transactions in multiple countries, demonstrating the scalability and reliability of enterprise-grade LMOS in production environments.
