Experimenting with the proposed Cross-Origin Storage API in Transformers.js

Transformers.js allows Web developers to integrate AI models. A challenge arises with caching: even if multiple applications use the same AI models or Wasm runtime files, browsers re-download and re-cache them if they originate from different top-level sites. This is due to cache isolation, a security measure preventing timing attacks by partitioning caches based on the top-level site and current-frame site, leading to redundant downloads and storage.
