Purchases

L3M starts with a 14-day free trial of everything. After the trial, a one-time unlock keeps it for good: there is no subscription and nothing renews. If you already unlocked L3M on this Apple ID, tap Restore Purchases on the paywall.

A model won't fit on my device

Every model shows whether it runs well, runs with tight memory, needs a check on your device, or won't run, with the memory arithmetic behind the verdict. A model that won't run on your device can't be downloaded there. Try a smaller model, or use Apple's on-device model on devices that have Apple Intelligence, which needs no download.

Downloads

Models are large. Downloads use Wi-Fi only by default, and you can allow cellular in Settings. A download that loses its connection waits and resumes. Each download is checked against its published size and fingerprint.
