## What it is
Python bindings for Apple's Foundation Models framework, giving access to the on-device foundation model behind Apple Intelligence on macOS. It supports streaming text generation, guided generation with typed structured outputs, and batch evaluation of Swift app AI features from Python.

## Use cases
- run on-device LLM inference on macOS with Apple Intelligence
- generate structured typed objects from a Python class schema
- evaluate Swift app Foundation Models features from Python
- stream real-time text generation responses
- analyze transcripts exported from Swift apps

## When to choose
- you're on macOS 26+ with Apple Intelligence and want Python access to the system model
- you need type-safe guided generation with constrained outputs
- you want to evaluate on-device model behavior using Python's data/ML ecosystem

## When to avoid
- you're on Linux, Windows, or older macOS versions
- you need cloud-hosted or cross-platform LLM access
- you need a mature project accepting contributions
