Summary
User benchmarks Qwen3.6-35B-A3B on an M1 Max 64GB, reporting 464 tok/s prefill and 62 tok/s decode at a 128K prompt with the MTPLX M1 fork.
Setup is the MTPLX M1 fork v2.12.2-m1.11 with mlx-community 4-bit group-64 weights plus an MTP head, 8-bit paged affine KV cache, and speculative decoding on. Splash-M1 1.3.2-m1.1 reached 302 tok/s prefill and 41 tok/s decode at 128K, and oMLX 385 tok/s prefill and 33 tok/s decode.
The fork was faster from 8K up on agent logs, 1.46x prefill and 1.5x decode at 128K, while Splash-M1 used less memory (23.5 GB vs 28.1 GB at 128K). The same post also compares Qwen3.8-27B, where the fork reached 132 tok/s prefill and 25.0 tok/s decode at 128K. Only the 2K, 32K and 128K agent-log cells were run three times; the rest are single runs.
