Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
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.
BaseRT
Fast open-source LLM inference for Apple Silicon, on-device
Best for you if:
- • Optimized runtime for Apple Silicon delivering significant speedups compared to alternatives.
- • Enables local model serving for coding agents, ensuring data privacy by keeping everything on the user's machine.
