+**Qwen3-Coder Next DFlash**, the DFlash speculative-decoding **draft** converted to GGUF by [Atomic Chat](https://atomic.chat). Built straight from [z-lab](https://huggingface.co/z-lab)'s original weights. Runs fully offline.
+## What this is
+[DFlash](https://github.com/z-lab/dflash) is a speculative-decoding method that drafts a whole **block** of candidate tokens in a single forward pass using a lightweight block-diffusion model, instead of one token at a time. This repo is the **draft component only** — it does nothing on its own. You run it alongside the target model **`Qwen/Qwen3-Coder-Next`**, which verifies the drafted block and keeps the longest correct prefix. Output is identical to running the target alone, just faster.
+> [!NOTE]
+> These GGUFs are **converted from z-lab's original weights**, not a repack of someone else's GGUF. `Q8_0` and `bf16` give the same draft acceptance, so `Q8_0` is the pick.
+## Run in llama.cpp
+Needs a build of [llama.cpp](https://github.com/ggml-org/llama.cpp) with DFlash speculative decoding (PR #22105). You supply the target as `-m` and this draft as `-md`:
+```bash
+./llama-server \
+    -m   Qwen3-Coder-Next.gguf \
+    -md  Qwen3-Coder-Next-DFlash.Q8_0.gguf \
+    --spec-type draft-dflash --spec-draft-n-max 15 \
+    -ngl 99 -fa on --jinja -c 8192
+```
+DFlash is trained for **non-thinking** generation — pass `enable_thinking=false` in the chat template for best acceptance.
+## Choosing a quant
+| Quant | Size | Notes |
+|---|---|---|
+| **`Q8_0`** | 0.51 GB | **Recommended.** Same acceptance as bf16, half the size and slightly faster drafting. |
+| `bf16` | 0.95 GB | Full-precision draft (reference). No acceptance gain over Q8_0. |
+## Performance
+z-lab report up to **6.17x** lossless acceleration for Qwen3-8B on their reference stack (vLLM / SGLang / Transformers). In `llama.cpp` today the DFlash port is newer: on our RTX 4090 test (Q8_0 target + Q8_0 draft, code generation) it delivered about **2.3x** end-to-end at roughly **26%** draft acceptance. Acceptance is set by the implementation and the content, not by the quantization (bf16 and Q8_0 measure the same). Speedups grow on structured/code output and shrink on free-form prose.
+## How this was made
+1. Download the DFlash draft `z-lab/Qwen3-Coder-Next-DFlash` (original weights).
+2. Convert to GGUF with [llama.cpp](https://github.com/ggml-org/llama.cpp) `convert_hf_to_gguf.py --target-model-dir` (the target supplies the tokenizer; its weights are not needed).
+3. Quantize the draft to `Q8_0`.
