Qwen3.8-Flash-Next MTP block (1.4 GB)

The MTP (multi token prediction) block of Qwen3.8-Flash-Next as a standalone GGUF: the 32 blk.48.* tensors and the model metadata, nothing else. It is meant for GGUF releases that ship without the block, such as ISTA-DASLab/Qwen3.8-Flash-Next-GSQ-RCO-GGUF, so that speculative decoding works without downloading a second full model.

Qwen3.8-Flash-Next-MTP-block.gguf 1.52 GB (1.41 GiB) bbb435d7ba548ddd5b2d6f660863bf56836e76f2b7d7ef98fa2c983fd0fefae1

Quantization: Q4_K gate/up experts, MXFP4 down experts, Q8_0 dense projections, F16 hyper-connection mixers.

Where it comes from

The tensors are copied byte for byte from ivanfioravanti/Qwen3.8-Flash-Next-DS4-IQ2, which was quantized from the original Qwen/Qwen3.8-Flash-Next weights. Nothing was requantized or retrained here.

Usage

With the paperniuk/ds4 fork of DwarfStar (branch m1-flash-next):

hf download paperniuk/Qwen3.8-Flash-Next-MTP-block --local-dir ~/models/flash-next/mtp

M=~/models/flash-next/Q2_0
DS4_QWEN_NGRAM_GGUF=$M/Qwen3.8-Flash-Next-GSQ-RCO-Q2_0-00002-of-00002.gguf \
DS4_QWEN_MTP_GGUF=~/models/flash-next/mtp/Qwen3.8-Flash-Next-MTP-block.gguf \
./ds4-server -m $M/Qwen3.8-Flash-Next-GSQ-RCO-Q2_0-00001-of-00002.gguf \
    --ctx 262144 --prefill-chunk 2048 --mtp

Measurements

M1 Max 64 GB, ISTA Q2_0 main model, 4K context, greedy, 400 tokens. Output is identical to plain decoding in every run.

Prompt No MTP This block ggml-org mtp-...-Q8_0.gguf (3.9 GB)
Code 34.6 tok/s 42.7 to 43.8 tok/s 43.2 tok/s
Prose 33.6 tok/s 37.9 tok/s 37.7 tok/s

First draft acceptance: 91% on code, 70% on prose. The larger Q8_0 block from ggml-org also works with the fork and is as fast; this one needs 1.2 GiB less memory.
