A Swift package that gives every app a single, unified chat interface across cloud and on-device AI providers. OpenAI, Anthropic, and Apple Intelligence all share the same protocol, message model, and optional SwiftUI components — swap providers with a one-line change.

Adds on-device Apple MLX inference to any app already using AIChatKit. Models are downloaded from Hugging Face Hub on first use and cached locally. Runs on Metal GPU and Apple Neural Engine — no network calls during inference.

Adds on-device GGUF inference via llama.cpp to any app already using AIChatKit. Models run entirely in-process using Metal GPU acceleration — no network calls after the initial download.
