The LUMI AI Factory is a three-year European initiative from March 2025 to February 2028 designed to accelerate AI innovation by providing a comprehensive one-stop-shop built on the LUMI supercomputer. It aims to empower SMEs and start-ups, researchers and public sector across Europe. This document will describe the roadmap of the core services of the LUMI AI Factory and the planned roadmap for delivery of the maturity levels of the services, as well as when the services will be deployed, and to whom the services will be available. The Service Portfolio will be divided into a Service Catalogue for external use and a Service Portfolio for internal use. The document includes a Service Catalogue draft with initial information on the availability of the services. Key services will be progressively rolled out and include: • Powerful AI Computing: Scalable access to GPU-accelerated resources for training and deploying everything from conventional ML models to massive foundation models, including secure environment for sensitive data • Data Services: Access to a curated library of datasets ("Dataset-as-a-Service") and expert support for data management and integration • Expert Support & AI Adoption: Direct consultation for technical challenges, grant applications, and business-focused programs like "Try & Buy" projects to ease into large-scale AI • Training & Skill Development: A full range of courses, hackathons, summer schools, and an accelerator program for AI start-ups • Collaboration Hubs: A physical co-working hub in Otaniemi, Finland, including virtual spaces, matchmaking and community building across borders Through this roadmap, the LUMI AI Factory will not only deliver advanced technical services but also measurable impact: strengthening European sovereignty in AI, lowering entry barriers for SMEs, accelerating public-sector digitalisation, and equipping a new generation of AI professionals with the skills to thrive in a rapidly evolving ecosystem. This document will be revised annually twice to reflect in increasing detail the current and evolving status of the service development roadmap, portfolio and catalogue.
