MLX LM: LLM Inference and Fine-Tuning on Apple Silicon

Fri, 01 May 2026 00:00:00 +0000

The promise of running LLMs locally on a MacBook has been seductive but incomplete. Ollama and llama.cpp made it possible, but performance left room for improvement — models ran, but they did not fully leverage Apple Silicon’s architecture. The gap between what a MacBook could theoretically do and what inference engines delivered was visible in every benchmark.

MLX LM closes this gap. Built on Apple’s own MLX framework, it runs LLM inference and fine-tuning at speeds that previously required dedicated GPU hardware. The key is MLX’s unified memory architecture — no data copying between CPU and GPU, no PCI-e bottlenecks, just direct access to the full memory bandwidth of Apple Silicon. For a MacBook Pro with an M4 Max, MLX LM delivers inference performance that rivals mid-range NVIDIA GPUs.
