The Biggest Brains Live in the Cloud Glossary
The Biggest Brains Live in the Cloud names a current form of frontier dependence: the most capable hosted AI systems combine large or unreleased models with memory capacity, accelerators, networking, serving software, tools, and other infrastructure that an ordinary local workstation cannot reproduce.
A local workstation can be sovereign and useful, but in 2026 it cannot reproduce every frontier service. Some model weights are unavailable, some models exceed local hardware limits, and some advertised capability belongs to the hosted system around the model rather than to the weights alone.
This is why Workflow-layer Sovereignty matters. Local systems can own memory, tools, files, routine work, privacy-sensitive work, and much of the operator’s day-to-day process. But the hardest reasoning and synthesis may still require frontier providers.
The practical response is to use frontier systems when their additional capability is needed while keeping suitable memory, tools, files, routine work, and privacy-sensitive work under local control.
