EAGLE-3 Draft Model for Qwen3-VL-8B-Instruct
Model Overview
This repository contains an EAGLE-3 style draft model specifically trained to accelerate the inference of the Qwen3-VL-8B-Instruct large language model.
This is not a standalone model. It must be used in conjunction with its corresponding base model (Qwen3-VL-8B-Instruct) within a speculative decoding framework to achieve significant speedups in text generation.
- Base Model:
Qwen3-VL-8B-Instruct - Model Architecture: EAGLE-3 (Speculative Decoding Draft Model)
- Primary Benefit: Accelerates text generation throughput by 1.5x to 2.5x without compromising the generation quality of the base model.
What is EAGLE?
EAGLE (Extrapolative A* Generative Language Engine) is an advanced speculative decoding method. It uses a small draft model to generate a sequence of draft tokens in parallel. These tokens are then verified by the larger, more powerful base model in a single forward pass. If the draft is accepted, the generation process advances multiple steps at once, leading to a substantial increase in speed.
This model serves as the "draft model" in this process. Its average acceptance length (acc_length) on standard benchmarks is approximately 1.87 tokens (with 4 draft tokens), meaning on average, it helps the base model advance nearly 2 tokens per verification step.
Performance
This model was evaluated on a diverse set of benchmarks. The acc_length (average number of accepted draft tokens) indicates the efficiency of the acceleration. A higher value is better.
| Benchmark | acc_length (num_draft_tokens=4) | acc_length (num_draft_tokens=8) |
|---|---|---|
| math500 | 2.30 | 2.55 |
| humaneval | 2.23 | 2.43 |
| gsm8k | 2.05 | 2.15 |
| ceval | 1.84 | 1.93 |
| cmmlu | 1.81 | 1.88 |
| mtbench | 1.76 | 1.83 |
| Average | ~2.00 | ~2.13 |
These results demonstrate consistent and effective acceleration across various tasks, including coding, math, and general conversation.

模型简介
本仓库包含一个 EAGLE-3 风格的草稿模型，专为加速 Qwen3-VL-8B-Instruct 大语言模型的推理而训练。
请注意：这是一个非独立模型。它必须与对应的基座模型 (Qwen3-VL-8B-Instruct) 在推测解码 (speculative decoding) 框架下配合使用，才能实现显著的文本生成加速效果。
- 基座模型:
Qwen3-VL-8B-Instruct - 模型架构: EAGLE-3 (推测解码草稿模型)
- 核心优势: 在不牺牲基座模型生成质量的前提下，将文本生成吞吐量提升 1.5 到 2.5 倍。
什么是 EAGLE？
EAGLE (Extrapolative A* Generative Language Engine) 是一种先进的推测解码方法。它利用一个轻量的草稿模型并行生成一系列草稿词元 (draft tokens)，然后由更大、更强的基座模型通过单次前向传播进行验证。如果草稿被接受，生成过程就能一次性前进多个步骤，从而实现显著的速度提升。
性能表现
本模型在一系列多样化的评测基准上进行了评估。acc_length (平均接受的草稿词元数) 反映了加速的效率，数值越高越好。
| 评测基准 (Benchmark) | acc_length (num_draft_tokens=4) | acc_length (num_draft_tokens=8) |
|---|---|---|
| math500 | 2.30 | 2.55 |
| humaneval | 2.23 | 2.43 |
| gsm8k | 2.05 | 2.15 |
| ceval | 1.84 | 1.93 |
| cmmlu | 1.81 | 1.88 |
| mtbench | 1.76 | 1.83 |
| 平均值 | ~2.00 | ~2.13 |
这些结果表明，该模型在编码、数学和通用对话等不同任务上都能提供稳定且高效的加速效果。
