Deutsche Telekom developed a scalable multi-agent enterprise platform called LMOS (Language Models Operating System), leveraging Qdrant to facilitate AI-powered customer service across its European subsidiaries. Faced with challenges in deploying AI agents at scale, the company recognized the complexity of integrating distributed systems with AI and addressed issues such as data segregation, memory management, and real-time context sharing. Initially struggling with operational instability and maintenance complexities in their AI stack, Deutsche Telekom shifted towards a PaaS-first approach, allowing developers to build AI agents using familiar tools. The choice of Kotlin and JVM supported seamless integration with existing systems, while Qdrant was selected for its simplicity, efficiency, and compatibility with the PaaS model. This transition reduced the time to develop new AI agents and enabled the platform to handle over 2 million customer interactions. LMOS's modular, open-source architecture now invites broader collaboration, positioning Deutsche Telekom as a leader in scalable, enterprise-grade AI infrastructure.
