Reflection demos Beam building a live NYC subway map from MTA data

Reflection AI demonstrates its Beam system building a live-updating NYC subway map from publicly available MTA data.

According to Reflection's post on X, Beam checked authentication requirements, located subway and map geometries, and built the frontend and backend so the server keeps pulling live MTA updates.

Reflection says the demo shows that reasoning from Beam's reinforcement learning training generalizes across domains, including ML workflows. The post is the only report on the demo, and the claim about generalization is Reflection's own.
