apfel is a free, open-source tool that unlocks the built-in large language model (LLM) on Apple Silicon Macs running macOS 26 (Tahoe) by providing a command-line interface, OpenAI-compatible server, and interactive chat. It runs entirely on-device with no internet connection or data leaving the machine, offering zero cost, privacy, and integration with existing tools and workflows. apfel supports tool calling via the Model Context Protocol, enabling advanced capabilities like calculators or APIs, and aims to provide a fast, privacy-first AI experience directly on the Mac.
