Short on time? Here's the quick answer

We've tested both tools. Here's who should pick what:

Ollama

Run open-source LLMs locally with one command

Best for you if:

  • • Run leading open-source models locally
  • • One command to download and run models

oMLX

Fast local LLM inference on Apple Silicon with persistent SSD cache

Best for you if:

  • • Paged SSD KV caching eliminates recomputation by persisting cache blocks to disk, enabling sub-5-second TTFT on long contexts for coding agents.
  • • Continuous batching delivers up to 4x generation speedup at high concurrency, outperforming in-memory-only solutions.
