Validate activity before betting a new project on mlx-swift-chat. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between jan and mlx-swift-chat? jan: open source alternative to ChatGPT that runs offline locally. mlx-swift-chat: A multi-platform SwiftUI frontend for running local LLMs with Apple's MLX framework..
