User reports gpt-oss 20B MXFP4 at 63.3 t/s generation and 700.8 t/s prompt processing on a Mac mini M4 Pro with 64 GB unified memory. Setup is llama.cpp build 6280 with MXFP4 GGUF, F16 K/V cache, flash attention, one Metal device, and -ngl 99. The 63.3 t/s is a separate TG128 depth-zero test, not generation after the four large prompts; prompt rates fall from 700.78 t/s at 2048 tokens to 419.74 t/s at 32768.

User reports Qwen2.5-Omni-3B at 70.9 t/s generation and 1245.6 t/s prompt processing on an Apple M4 Pro with 64 GB unified memory. Setup is dasLLAMA version 16 with Q8_0 weights, f16 K/V cache, and one Metal GPU; the run used 512 synthetic prompt positions and 128 serial decode positions. The figures are engine-side loop wall time, not a 512-input/128-output chat request, and no speculative decoding was used.
