AFM MLX Squeezes More Mac Speed

This is the kind of unglamorous runtime work that actually moves the needle for local AI: less overhead, better throughput, and fewer wasted cycles in multi-turn agent workflows.

• –Native Swift matters here because the whole stack is trying to stay close to Apple Silicon and Metal instead of paying Python orchestration tax
• –Concurrent batch connections make more sense for multi-agent setups than a single chat loop, especially when each context needs its own lane
• –Prefix caching is the practical headline feature for long-running conversations, since it stops the model from recomputing the same prompt prefix over and over
• –The OpenAI-compatible API keeps adoption low-friction, so the performance gain can slot into existing tools rather than forcing a rewrite
• –The caveat is that this is a systems optimization, not a model breakthrough, so the win depends on how well your workload maps to local Mac inference
