Architecture

Device, phone, local-host and cloud processing across documented product configurations.

## Processing stages

An AI device can capture input locally and use another computer for inference, response generation or storage. Architecture comparisons require documentation for each stage and its connection requirements.

## Local hosts and endpoints

Home Assistant Voice Preview Edition is an endpoint. Its voice pipeline can use a separate local host or cloud services. Local operation of the complete setup does not establish that the endpoint itself runs a language model.

## Feature-level routing

Brilliant Labs describes an NPU inside Halo, models on the phone and a cloud-based agent. The reviewed documentation leaves some feature-level routing and offline-operation requirements unresolved.

## Privacy and network dependencies

Local processing capability and privacy are separate properties. A local-capable computer can run software that contacts external services. Privacy assessment requires data-flow documentation for the specific feature and configuration.

This is our interpretation of the linked documentation. No hands-on testing or independent benchmarking was performed.
