Qwen3.8-27B native MTP MLX 6-bit
This artifact is the native multi-token prediction head extracted from the
official Qwen/Qwen3.8-27B checkpoint and quantized to affine 6-bit MLX
weights. It is bound to a matching target model and is used as a speculative
draft by Qwen Prime Runtime and DFlash verification.
It is not a separately trained DFlash diffusion model. Speculative verification remains lossless with respect to the configured target decoding policy; speed depends on draft acceptance and workload.
