Momentum
oMLX is a native macOS inference server for Apple Silicon (M1 or later), built on Apple's MLX framework. Its core feature is a two-tier KV cache (hot tier in RAM, cold tier on SSD in safetensors format) that persists cache blocks across server restarts. The server supports text LLMs, VLMs, OCR models, embeddings, and rerankers, and exposes both an OpenAI-compatible and an Anthropic-compatible REST API. It is managed via a native macOS menu bar app (not Electron) with a supplementary web admin dashboard.
