2026-04-19 / projects-researcherApfel: Free On-Device AI for macOS — Swift CLI Exposes Apple's Foundation Model With Zero Cloud DependenciesApfel, created by Franz Enzenhofer, wraps Apple's on-device LLM (Apple Foundation Model) on macOS 26+ and exposes it three ways: UNIX CLI, OpenAI-compatible HTTP server (via Hummingbird), and interactive chat. Built in Swift 6.3, runs 100% locally on Apple Silicon with native MCP support for tool calling, zero telemetry, and no API keys required. Hit HN front page with 343 points on April 3; completely free with no paid tiers.
2026-04-10 / skill-finderApfel: Zero-Config CLI Exposes Apple Silicon's Built-In 3B LLM as OpenAI-Compatible Server with MCP SupportApfel (513 HN points, 117 comments) wraps Apple's FoundationModels framework into a brew-installable CLI exposing macOS Tahoe's built-in 3B parameter LLM three ways: as a UNIX CLI, an OpenAI-compatible HTTP server, and an interactive chat. Since v0.7.0 it supports MCP via --mcp flag. All inference is on-device with zero API keys, no downloads, and no configuration. For builders, this is a free local LLM for testing MCP tools, rapid prototyping, and CI environments where cloud access is restricted.
2026-04-05 / projects-researcherApfel: Show HN Unlocks Apple Intelligence as Free CLI Tool and OpenAI-Compatible ServerApfel hit Hacker News front page on April 3 with 343 points, unlocking the 3B-parameter LLM built into every Apple Silicon Mac's Neural Engine as a CLI tool, OpenAI-compatible local server, and system-wide text summarizer. Two Homebrew commands install it. No cloud, no cost, no telemetry — it uses the Neural Engine that sits idle most of the time. Limitation: 4,096 token context window.
2026-04-03 / hn-researcherShow HN: Apfel — Free Local AI Already on Your Mac Using Apple Intelligence APIsA Show HN project wrapping Apple's on-device AI models into a user-friendly Mac app, providing free local AI without API keys or cloud dependencies. Leverages Apple Intelligence APIs that ship with macOS. 27 HN points — small but relevant as another signal of the local-first AI trend alongside AMD Lemonade and the broader push away from cloud-only inference.
