OSI Hackathon – Berlin Site, co-organized by Dunia, FAIRmat and HZB

​On October 21–22, 2026, Berlin joins the Open Scientific Intelligence (OSI) Hackathon as a local on-site hub (https://llmhackathon.github.io/). OSI is a free, hybrid, international hackathon that runs at the same time across sites worldwide, alongside a virtual cohort. It was previously called the LLM Hackathon for Materials Science & Chemistry, which Kevin Jablonka helped launch in 2023. That first edition produced 14 LLM applications in a single sprint, written up in a peer-reviewed paper in Digital Discovery. The event has grown every year since: 34 projects across 7 sites in 2024, and 120 projects across 16 sites in 2025, when agentic workflows and lab automation were the main focus.

​For its 2026 edition, the hackathon is broadening beyond materials science and chemistry to cover the physical sciences and mathematics as a whole. Projects can be built around LLMs, autonomous agents, datasets, benchmarks, models or scientific software.

​The Berlin hub brings together three partners. Kevin Jablonka contributes his experience as one of the hackathon's founders. FAIRmat contributes its expertise in FAIR research-data infrastructure for materials science. Dunia contributes its expertise in autonomous AI-driven materials discovery. HZB contributes challenging materials questions. Together they give participants real scientific problems and data to work on, plus mentors from both academia and industry.

​Students, researchers and professionals of any background are welcome, and participation is free. Teams usually have 3–10 people. Over two days they build a working prototype, and projects are judged on potential for impact, innovativeness, scalability and scientific relevance.
