Powering Science: How SYNAPS-I Builds on Meta’s Open Source AI

SYNAPS-I, a DOE initiative led by Berkeley Lab, unites 60 researchers across five labs to speed up X-ray and neutron data analysis using AI. Because prepublication data must stay on secure government systems, open-source models from Meta — SAM 3 and DINOv3 — let the team fine-tune cutting-edge AI entirely in-house. Read more »
