User reports Qwen3.6 35B-A3B at 154 t/s on a 2024 MacBook Pro M4 Pro with 48GB, using the Kapitsa engine. Setup is Kapitsa, an open-source Metal engine for Apple Silicon, with 4-bit MLX weights and DFlash2 speculative decoding; part of the 27B's prefill runs on the Neural Engine. The same table gives Qwen3.8 27B at 63 t/s and Qwen3.5 4B at 179 t/s on the M4 Pro, and on an M5 Max 128GB Qwen3.6 35B reaches 281 t/s. The author says not to trust benchmarks and notes Kapitsa is not fastest on the M5 Max for Qwen3.8 27B (102 vs mlx-serve's 130) or Flash-Next.
