mlx-engine is the Apple MLX-based LLM inference engine that powers LM Studio on Mac, built on mlx-lm with support for vision models via mlx-vlm and structured output via Outlines. It can also be used standalone for model loading and text/vision inference on Apple Silicon.

Use cases

• run local LLM inference on Apple Silicon Macs
• serve MLX models inside LM Studio
• run vision-language models like Pixtral locally on Mac
• generate structured JSON output from local LLMs
• test MLX model inference from the command line

When to choose

• you want fast local LLM inference on Apple Silicon with MLX
• you use LM Studio on Mac and want to extend or understand its MLX engine
• you need vision model support with MLX

When to avoid

• you need inference on NVIDIA GPUs or non-macOS platforms
• you need a production serving stack with OpenAI-compatible APIs out of the box
• you don't use macOS 14+ or Python 3.11
