Let's Meet Up!

Join one of our hackathons and help shape the future of open machine learning

Changing the world requires focused, deep work

In hackathon-style events, we break away from routine and work for entire weeks on new ideas that push the scientific community forward. From building cool extensions of OpenML itself to solving data-driven problems in novel ways, we believe in open science and democratizing machine learning for everyone.
