# DFlash: Block Diffusion for Flash Speculative Decoding\n[**Paper**](https://arxiv.org/abs/2602.06036) | [**Blog**](https://z-lab.ai/projects/dflash/) | [**Models**](https://huggingface.co/collections/z-lab/dflash)\n\n**DFlash** is a lightweight **block diffusion** model designed for speculative decoding. It enables efficient and high-quality parallel drafting.\n\n\n\nhttps://github.com/user-attachments/assets/5b29cabb-eb95-44c9-8ffe-367c0758de8c\n\n## Supported Models\n\n| Model | DFlash Draft |\n|---|---|\n| gemma-4-26B-A4B-it | [z-lab/gemma-4-26B-A4B-it-DFlash](https://huggingface.co/z-lab/gemma-4-26B-A4B-it-DFlash) |\n| gemma-4-31B-it | [z-lab/gemma-4-31B-it-DFlash](https://huggingface.co/z-lab/gemma-4-31B-it-DFlash) |\n| Qwen3.6-27B | [z-lab/Qwen3.6-27B-DFlash](https://huggingface.co/z-lab/Qwen3.6-27B-DFlash) |\n| Qwen3.6-35B-A3B | [z-lab/Qwen3.6-35B-A3B-DFlash](https://huggingface.co/z-lab/Qwen3.6-35B-A3B-DFlash) |\n| MiniMax-M2.5 (Preview) | [z-lab/MiniMax-M2.5-DFlash](https://huggingface.co/z-lab/MiniMax-M2.5-DFlash) |\n| Kimi-K2.5 | [z-lab/Kimi-K2.5-DFlash](https://huggingface.co/z-lab/Kimi-K2.5-DFlash) |\n| Qwen3.5-4B | [z-lab/Qwen3.5-4B-DFlash](https://huggingface.co/z-lab/Qwen3.5-4B-DFlash) |\n| Qwen3.5-9B | [z-lab/Qwen3.5-9B-DFlash](https://huggingface.co/z-lab/Qwen3.5-9B-DFlash) |\n| Qwen3.5-27B | [z-lab/Qwen3.5-27B-DFlash](https://huggingface.co/z-lab/Qwen3.5-27B-DFlash) |\n| Qwen3.5-35B-A3B | [z-lab/Qwen3.5-35B-A3B-DFlash](https://huggingface.co/z-lab/Qwen3.5-35B-A3B-DFlash) |\n| Qwen3.5-122B-A10B | [z-lab/Qwen3.5-122B-A10B-DFlash](https://huggingface.co/z-lab/Qwen3.5-122B-A10B-DFlash) |\n| Qwen3-Coder-Next | [z-lab/Qwen3-Coder-Next-DFlash](https://huggingface.co/z-lab/Qwen3-Coder-Next-DFlash) |\n| Qwen3-Coder-30B-A3B | [z-lab/Qwen3-Coder-30B-A3B-DFlash](https://huggingface.co/z-lab/Qwen3-Coder-30B-A3B-DFlash) |\n| gpt-oss-20b | [z-lab/gpt-oss-20b-DFlash](https://huggingface.co/z-lab/gpt-oss-20b-DFlash) |\n| gpt-oss-120b | [z-lab/gpt-oss-120b-DFlash
