oMLX
Native macOS server for fast local AI model inference
Overview
What is oMLX?
oMLX is a native macOS inference server for running local AI models on Apple Silicon using Apple's MLX framework. It provides paged SSD KV caching to reduce time-to-first-token for coding agents, continuous batching for higher throughput, and OpenAI- and Anthropic-compatible APIs. oMLX supports LLM, vision-language, embedding, and reranker models, along with tool calling, MCP integration, multi-model serving, and a native menu bar application with a web dashboard.
What is oMLX used for?

Top Features
- Paged SSD KV caching for faster responses and reduced time-to-first-token
- Continuous batching for concurrent request throughput
- OpenAI-compatible and Anthropic-compatible APIs
- Native macOS menu bar application
- Web dashboard for model management, chat, and real-time metrics
- Multi-model serving for LLM, VLM, embedding, and reranker models
- Tool calling and MCP integration
- Support for MLX-format models from Hugging Face
- LRU model eviction when memory is limited
- Automatic reuse of Hugging Face and LM Studio model caches
How to use oMLX?
Download the signed macOS DMG and drag oMLX to the Applications folder, then configure the model directory, start the server, and download or select an MLX-format model. Alternatively, install from source with Python 3.10+ using the provided Git commands and run omlx serve with a model directory. Connect Claude Code, OpenClaw, Cursor, or other compatible clients through the OpenAI or Anthropic API endpoints.
