Tipster Says Apple Is Developing Harbor for Local AI on Macs

An unnamed tipster claims Apple is developing Harbor, a Mac app for running open-weight AI models locally, and says Claris is privately previewing the software.

The tipster says Harbor would run models on Macs with Apple silicon without requiring data to be uploaded to the cloud. The account describes connecting two or more compatible Macs over Thunderbolt 5 and combining their unified memory in a cluster. That setup could handle models too large for one computer or more simultaneous requests, without manual configuration or command-line use.

The tipster says no official launch timing has been announced.
