apfel is an open-source Swift 6.3 binary that exposes Apple's on-device LLM (available on every Apple Silicon Mac with macOS 26 Tahoe) as a CLI tool, OpenAI-compatible HTTP server, and interactive chat. It bridges the gap between Apple's FoundationModels framework — which requires a Swift app — and everyday terminal workflows, shell scripts, and OpenAI SDK integrations. Key limitations: 4,096-token context window, single fixed model, Apple Silicon only.
