# Function getDefaultAvailableModelsCache

- getDefaultAvailableModelsCache(): AvailableModelsCache

  Get (or lazily construct) the process-default cache. Starts with no sources — adapter factories register themselves via `addSource` on construction. Until at least one source is added, the cache returns empty snapshots and `withModelNotFoundFallback` degrades to surfacing the original error (safe).

  #### Returns AvailableModelsCache
