Open Scientific Intelligence (OSI) Hackathon
-
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.
