Short on time? Here's the quick answer

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

BaseRT

Fast open-source LLM inference for Apple Silicon, on-device

Best for you if:

  • • You want fast inference speeds, especially on prefill and decode phases
  • • You want keeps data fully local, enhancing privacy and security for sensitive work

oMLX

Fast local LLM inference on Apple Silicon with persistent SSD cache

Best for you if:

  • • You want dramatically reduces TTFT on long contexts for coding agents by persisting KV cache to SSD
  • • You want significant throughput improvements with continuous batching at high concurrency

In-Depth Analysis

BaseRTBaseRT

Fast open-source LLM inference for Apple Silicon, on-device

Starts at Free
Great value

BaseRT is completely free at $0/month, making it an exceptionally generous offering for Apple Silicon users.

Watch out

May lack features of paid runtimes (e.g., quantization options)

Strengths

  • +Fast inference speeds, especially on prefill and decode phases.
  • +Keeps data fully local, enhancing privacy and security for sensitive work.
  • +Free and open-source, with active community support.

Weaknesses

  • -Only compatible with Apple Silicon (M-series) hardware.
  • -Model support may not cover all open-source models available in other runtimes.

Key features

Supports a wide range of models: Qwen, Llama, Gemma, Mistral, Phi, Nomic BERT, and more.Serves models via a simple `basert serve` command for integration with coding agents.Installs with a single curl command for quick setup.Delivers significantly faster prefill tokens per second compared to MLX and llama.cpp.Community-driven development with documentation, GitHub repository, and Discord chat.

oMLXoMLX

Fast local LLM inference on Apple Silicon with persistent SSD cache

Starts at Free

Strengths

  • +Dramatically reduces TTFT on long contexts for coding agents by persisting KV cache to SSD
  • +Significant throughput improvements with continuous batching at high concurrency
  • +Seamless integration with popular coding tools via OpenAI/Anthropic compatible APIs

Weaknesses

  • -Requires macOS 15+ and Apple Silicon, limiting compatibility to recent Mac hardware
  • -Large models demand substantial RAM (64GB+ recommended), making it less accessible on lower-end Macs

Key features

Paged SSD KV caching with two-tier RAM/SSD architecture and LRU eviction policyContinuous batching via mlx-lm's BatchGenerator for concurrent request handlingNative macOS menu bar app with web dashboard for model management and real-time metricsMulti-model serving supporting LLM, VLM, embedding, and reranker models simultaneouslyOpenAI and Anthropic drop-in API endpoints with one-click config generator for tools like Claude Code and CursorTool calling support for JSON, Qwen, Gemma, GLM, and MiniMax formats with MCP integration
