mlx_lm.server
A local LLM inference server included with Apple's MLX framework, optimized for Apple Silicon chips, but lacking the priority scheduling and fault tolerance capabilities required for multi-agent scenarios.
Timeline (last 90 days)
mlx-lm ships with mlx_lm.server, an OpenAI-compatible HTTP server that exposes /v1/chat/completions, /v1/completions, and /v1/models, and listens on 127.0.0.1:8080 by default.
mlx_lm.server implements only basic security checks, and upstream explicitly does not recommend it for production environments.
Mainstream local inference servers (llama-server, Ollama, mlx_lm.server) do not have priority scheduling or checkpoint recovery capabilities, and are designed for data center rack throughput.
Official measurements: after the inference worker is killed midway through streaming output, Superfluid restores service within 1.8 seconds and keeps the stream intact; Ollama also restores within 1.8 seconds but the stream is truncated; llama-server and mlx_lm.server have no checkpoint recovery capability.
When 32 requests share the same 4k-token system prompt, Superfluid's prefix cache hit rate reaches 97%, on par with Ollama, while mlx_lm.server is 0%.
Superfluid batches MLX requests, which is more efficient than mlx_lm.server's one-by-one processing.
