The Take
Capability access is expanding — export controls dropping, new agentic models shipping, cheaper local inference arriving — while the fine print on cost, provenance, and output transparency tightens in the same window. Engineers who haven't revisited billing models, output-tagging assumptions, and OSS contribution policies are already operating on stale assumptions.
