One of the very first announcements on this year’s WWDC was that for the first time, third‑party developers will get to tap directly into Apple’s on‑device AI with the new Foundation Models framework. But how do these models actually compare against what’s already out there?

With the new Foundation Models framework, third-party developers can now build on the same on-device AI stack used by Apple’s native apps.

In other words, this means that developers will now be able
