The federation-layer position for AI model coordination across boundaries.

A meta-category coordinate for the infrastructure that enables AI models to collaborate, share state, and coordinate across organizational, trust, and infrastructure boundaries — the federation layer of the model stack.

Why this is canonical

'Model federation' names the architectural challenge that distributed AI deployment creates: how do models from different organizations, vendors, or trust domains coordinate without centralizing sensitive data or ceding control? Federated learning, federated inference, and federated model registries are all active research and product areas. The .ai TLD makes this the native-era formulation of the federation problem at the model layer.

Where it fits

A few directions this coordinate opens —

Federated learning and privacy-preserving AI
A product brand for federated model training and inference infrastructure — models that coordinate across data silos without centralizing sensitive information.
Privacy-preserving AI platforms, federated learning infrastructure companies, healthcare and finance AI vendors
Multi-organization model coordination
A home for the infrastructure that enables competing organizations to share model capabilities, benchmarks, or evaluations under federated governance.
AI infrastructure companies, consortium-model platforms, government AI sharing programs

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
