MLX-LM, Apple M4

Qwen3-0.6B, warm, batch 1, 6 interleaved runs.

Axis	vllm.cpp	MLX-LM	Ratio
Prefill TTFT	524.5 ms	532.6 ms	1.015x
Decode	27.23 tok/s	27.85	0.978x
Warm total	24.37 tok/s	24.96	0.976x

The 2.4% is a real gap, not noise: our spread was 0.12% and MLX-LM’s 0.34%. All of it sits in decode, 0.81 ms per token. Indicative rather than binding: two models, 18 of 75 ops native, and the 97.6% needs the optional MLX GEMM provider shape-gated to prefill (95.9% on the default build).
