DeepSeek V4 Flash 0731 compact DSpark drafters

This repository contains the compact DSpark auxiliary for DeepSeek V4 Flash

1. It is not a standalone language model and does not include target-model

weights.

The routed experts use Q2_K. Dense projections use Q8_0. The 81-tensor GGUF

uses the standardized llama.cpp general.architecture=dflash schema.

The Q2_K artifact is the smallest option. The mixed artifact uses IQ2_XXS for

the gate and up routed-expert tensors and preserves the down routed-expert

tensors in native MXFP4. Its remaining quantized tensors use Q8_0. The mixed

recipe follows the small-drafter design from antirez/ds4 issue 642 and keeps

more expert fidelity while remaining suitable for 128 GiB Apple Silicon Macs.

The target, drafter, KV cache, runtime buffers, and other loaded models must

still fit together.

Unsloth publishes a full-MXFP4 Q8_0 drafter and a BF16 drafter. This repository

provides the smaller mixed expert recipe that Unsloth does not publish.

Provenance and verification

The source is deepseek-ai/DeepSeek-V4-Flash-0731 revision

9e165c30e2704aec5d9d593cce3eebd58bbef1cb. The repository contains the

pinned source manifest, the Q2_K converter, standardized dflash rewriters,

verification scripts, tests, build manifests, and checksums.

Both releases passed these schema checks:

• 81 canonical dflash tensors with 32-byte alignment.
• Byte-identical tensor payloads before and after the schema rewrite.
• Byte-identical repeated builds.
• Complete target-tokenizer metadata copied through the official llama.cpp

DeepSeek V4 DSpark converter at commit

15586e2d7165570fb3aa7c26e0d442e289ef69de, including

tokenizer.ggml.mask_token_id=128799.

• A real llama.cpp draft-dspark decode generated 120 draft tokens and

accepted 38, with no invalid -1 token.

• ns4 build e470f38280d9ff4f020c242233998562a88463ee loaded the corrected Q2

file and completed an exact 32-token decode, drafting 47 and accepting 12.

The Q2_K build also passed its numeric limits: maximum Q2_K block-relative

error 0.49072265625, below 0.5, and maximum Q8_0 block-relative error

0.00396728515625, below 0.01.

The mixed artifact was converted with antirez/ds4 pull request 645 at commit

d147270d7422ba0eb55985c8d4075b9dfaa84bf1. It uses the public routed-MoE

importance matrix from antirez/deepseek-v4-gguf. The build manifest pins its

revision, checksum, and the deterministic MTP alias transformation.

Compatibility

Use this file only with a compatible DeepSeek V4 Flash 0731 target. The runtime

must support the standardized llama.cpp dflash GGUF schema and the selected

Q2_K or IQ2_XXS/MXFP4 expert recipe.
