| **Qwen3 8B 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/Qwen3-8B`**, 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 Qwen3-8B.gguf \ | |
| -md Qwen3-8B-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`** | 1.12 GB | **Recommended.** Same acceptance as bf16, half the size and slightly faster drafting. | | |
| | `bf16` | 2.10 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/Qwen3-8B-DFlash-b16` (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`. | |
