Agent engineering, measured

Every figure here says where it came from

buildagentic tracks 46 open-source frameworks, language models and inference machines across 7 sources. Every value resolves to the source that reported it, the moment it was observed, and how it was measured. A figure that fails validation is withheld rather than shown — withheld means we refused to publish it, not that it is zero.
