Next edition · October 21–22, 2026
Formerly the LLM Hackathon for Materials Science & Chemistry — now open to the physical sciences and mathematics. Covering agents, LLMs, datasets, benchmarks, models, scientific software and more against the biggest problems. Free, hybrid, and international.
Every year, this hackathon brings together scientists, mathematicians, and AI researchers from around the world for an intense sprint: build something real, in teams, across time zones and on-site locations.
Three editions in, the frontier has moved past language models alone — so the event has expanded in scope. As the Open Scientific Intelligence (OSI) Hackathon, the 2026 edition expands from materials science and chemistry to the physical sciences and mathematics, and welcomes submissions in: LLMs, autonomous agents, datasets, benchmarks, models, scientific software, and more.
The 2025 edition produced automated research assistants, novel data pipelines, and agentic lab workflows — explore them on the awards page. The next edition runs October 21–22, 2026 — registration is open. Join the Slack community to find teammates or propose hosting a site.
14 LLM applications built in a single sprint, published as a peer-reviewed paper in Digital Discovery.
34 projects across 7 on-site locations and a worldwide virtual cohort, documented on arXiv.
Agentic workflows, tool use, and lab automation took center stage — 120 projects across 16 sites, documented on arXiv.
The event becomes the Open Scientific Intelligence Hackathon — expanding to the physical sciences and mathematics, where LLMs, agents, datasets, models, and scientific software are all fair game. Registration is open now; the detailed schedule follows.
2026 sponsorship is open — see who's on board and how to join them.
