Every iPhone 11 / 11 Pro / 11 Pro Max has 4 GB of RAM, whatever its storage (64 GB, 128 GB, 256 GB or 512 GB). A model runs in RAM (the 4.0 GB here), not in storage. Storage (64 GB, 128 GB, 256 GB or 512 GB on this version) only keeps the downloaded files, and even the smallest size has room for several. iOS lets one app hold only part of the RAM before it closes the app, so we plan around 1.8 GB; a model bigger than that won’t run. Phone apps such as PocketPal AI download a model once, then run it with no connection.
