## Executive Summary
With the recent release of the Muse family of foundational models, we want to take you inside the infrastructure that has made it all possible.

## Why It Matters (Strategic Analysis)
Operating a gigawatt-scale supercluster at over 85% goodput demonstrates that massive distributed training bottlenecks can be mitigated through hardware-software co-design, custom open rack power structures, and rigorous stability engineering. Managing multi-building GPU fabrics as a single unified machine sets a new operational benchmark for training frontier models with extended context windows.
