+
+## Overview
+
+This is the **AdaFlash drafter** for [Qwen3-8B](https://huggingface.co/Qwen/Qwen3-8B) — an on-policy distilled diffusion drafter with an adaptive length head, trained using PerfectBlend data and reverse-KL loss. It is initialized from [Qwen3-8B-DFlash-b16](https://huggingface.co/z-lab/Qwen3-8B-DFlash-b16).
+
+AdaFlash accelerates LLM inference through speculative decoding. The adaptive length head dynamically adjusts the number of draft candidates per step, balancing speed and acceptance rate.
+
+## Quick Start
+
+AdaFlash requires the patched [SGLang PR #34171](https://github.com/sgl-project/sglang/pull/34171) for serving.
+
+```bash
+# Install
+conda create -n adaflash python=3.12 -y && conda activate adaflash
+pip install "sglang[all] @ git+https://github.com/sgl-project/sglang.git@refs/pull/34171/head#subdirectory=python"
+
+# Serve
+export MODEL_PATH=Qwen/Qwen3-8B
+export DRAFT_MODEL_PATH=AdaFlash/Qwen3-8B-AdaFlash
+
+# Launch the server & benchmark
+bash scripts/tools/benchmark.sh
+```
+
+For full setup, training, and benchmark details, see the [GitHub repo](https://github.com/AdaFlash-project/AdaFlash).
