Meta calls its DOE lab AI open source. The license says otherwise. (ai.meta.com)
Two Meta vision models do the labeling: DINOv3 finds the structures, SAM 3 draws the pixel-precise boundaries around them, running across roughly 300 GPUs inside the DOE's Genesis Mission science program.
Meta's post calls the pipeline open source. A commenter who read the actual SAM 3 license found it bans reverse engineering and any weapons-related use, oddly restrictive wording for a federally funded lab.
