Our Mission

A commons for AI, built in the open

AI is being shaped right now — and too much of it is happening behind closed doors. Mass Open exists to make sure New England has a strong, visible, and welcoming home for open source AI.

We bring together the people who build, study, and care about open models — so the region's deep talent in research and engineering translates into technology everyone can inspect, use, and improve.

What We're About

Three things we believe in

    Championing open weights, open data, and reproducible research so the next wave of AI is built in the open — not behind closed doors.

  • Local Builders

    Connecting engineers, founders, researchers, and students across Boston, Cambridge, and the wider New England corridor.

  • Shared Knowledge

    Talks, meetups, and write-ups that turn scattered expertise into a commons everyone can learn from and build on.
