European AI Hackathon
HYBRID
Open Hackathons are multi-day, hands-on coding events that help developers and researchers accelerate, optimize, and scale their applications on a variety of data center architectures. Attendees work with dedicated mentors to identify and address data-loading bottlenecks, parallelize training, and optimize AI pipelines to accelerate experimentation and realize performance gains.
The European AI Hackathon, running from 6 October to 29 October 2026, targets small and medium-sized enterprises (SMEs), startups, industry practitioners, and researchers across Europe, with the aim of building AI-driven products and services. Teams benefit from personalized, expert guidance to take their AI workloads to the next level and access to leadership-class compute resources.
Examples of AI projects include:
Agentic Contract Intelligence: Multi-agent pipelines that parse, risk-score, and redline contracts across languages and jurisdictions
Real-Time Energy Grid Balancing: Agentic systems running thousands of parallel simulations to autonomously balance distributed energy resources within live decision windows
Legacy Code Modernization: Fine-tuning open-weight code LLMs on COBOL/Fortran codebases with long-context windows to enable enterprise migration
Autonomous Quality Inspection: Vision models running high‑FPS inference to detect defects on production lines. Predictive Maintenance at Scale: Multimodal LLMs that integrate sensor logs, manuals, and historical failures to recommend interventions
These projects are illustrations, not constraints. Any AI workload that benefits from scaling, speed-up, and hands‑on expert guidance is welcome.
Target audience
Applying teams should have a clear project ready for further development and scaling. Participating teams must be based in the EU and/or EuroHPC JU member countries. Please ensure that your team meets all prerequisites before you apply and use your company/institute email address in the application form.
