The FreeToken Weight (FTW) storage format is a pre-processed weight file format that stores expert parameters pre-merged into the normalized runtime bank layout ahead of time. By preparing the weights in advance according to the engine's exact runtime memory arrangement, the system completely bypasses tensor discovery, unpacking, and runtime weight repacking during startup. At engine launch, expert weights are loaded via parallel direct I/O as aligned chunks directly into pre-allocated, exact-size host banks, allowing rapid cold bootstrap prior to memory pinning.
