rxwei · x · 2026-09-21

macOS 27 now includes a new fm CLI that lets you call Apple's Foundation Models directly from the terminal.

rxwei, developer of SwiftChat, confirmed the CLI supports both the on-device model and Private Cloud Compute — local inference with seamless escalation to Apple's privacy-preserving cloud for heavier tasks. It's free, requires zero setup, and makes no privacy compromises, designed to enable effortless automations for Mac users.
