Coordinating agents
Until now, using Foundation Models in an app meant invoking a single model for a single task. Dynamic Profiles, announced at the June 9 Platforms State of the Union, change the base architecture: a developer can now define profiles with different instructions and contexts, and have multiple model instances cooperate on the same pipeline. A typical example is a flow that first drafts text, then evaluates it critically, then reformulates it according to specific constraints — three distinct agents, coordinated by the app without leaving the on-device ecosystem.
As reported by TechTimes, the framework already supports dynamic routing between on-device model, Private Cloud Compute, and server-side providers like Claude and Gemini. Dynamic Profiles integrate with this routing system: the active profile determines which capability level is invoked based on task complexity. Apple's documentation describes three main areas of the updated framework: server-side intelligence with Private Cloud Compute, dynamic sessions with instructions and profiles, and multimodal prompting for image analysis.
Developer implications
Group Labs dedicated to Foundation Models during WWDC 2026 are among the most attended of the entire week, a signal that developers — particularly those working on health, productivity, and creative apps — see multi-agent workflows as a concrete opportunity for this development cycle.
