Spec-Bench: A Comprehensive Benchmark and Unified
Evaluation Platform for Speculative Decoding
| Paper | Blog | Leaderboard | Roadmap |
Speedup comparison of Speculative Decoding methods on Spec-Bench, evaluated by Vicuna-7B-v1.3.
## Introduction
Spec-Bench is a comprehensive benchmark designed for assessing Speculative Decoding methods across diverse scenarios. Based on Spec-Bench, we aim to establish and maintain a unified evaluation platform for open-source Speculative Decoding approaches. This platform facilitates the systematic assessment of existing methods ***in the same device and testing environment***, thereby ensuring fair comparisons.
Currently, Spec-Bench supports the evaluation of the following open source models:
- [EAGLE-1,2,3](https://github.com/SafeAILab/EAGLE)
- [Hydra](https://github.com/zankner/hydra)
- [Medusa](https://sites.google.com/view/medusa-llm)
- [Speculative Sampling](https://huggingface.co/blog/assisted-generation)
- [Prompt Lookup Decoding](https://github.com/apoorvumang/prompt-lookup-decoding)
- [TokenRecycling](https://github.com/Luowaterbi/TokenRecycling)
- [REST](https://sites.google.com/view/rest-llm/)
- [Lookahead Decoding](https://lmsys.org/blog/2023-11-21-lookahead-decoding/)
- [SPACE](https://github.com/cteant/SPACE)
- [SAM-Decoding](https://github.com/hyx1999/SAM-Decoding)
Alongside the stable version, Spec-Bench now supports the latest transformers with multiple speculative decoding methods, including the SpS and Eagle series. For details, check out the [latest-transformer](https://github.com/hemingkx/Spec-Bench/tree/latest-transformer) branch.
## Update

**2025.03.18**: We have integrated [SAM-Decoding](https://github.com/hyx1999/SAM-Decoding) into Spec-Bench.
**2024.10.25**: We have integrated [EAGLE-2](https://github.com/SafeAILab/EAGLE) into Spec-Bench.
**2024.05.29**: We have integrated [SPACE](https://github.com/cteant/SPACE) into Spec-Bench.
**2024.05.16**: Our [paper](https://arxiv.org/abs/2401.07851) has been accepted by ACL 2024 Findings 🎉 !
**2024.03.12**: We now support statistics for [#Mean accepted tokens](https://github.com/hemingkx/Spec-Bench/blob/main/evaluation/speed.py#L65).
**2024.03.11**: We have integrated [Hydra](https://github.com/zankner/hydra) into Spec-Bench, check it out!
## Installation
```
conda create -n specbench python=3.12
conda activate specbench
cd Spec-Bench
pip install -r requirements.txt
```
## Model Weights
Download corresponding model weights (if required) and modify the checkpoint path in `eval.sh`.
- [vicuna-v1.3](https://huggingface.co/lmsys/vicuna-7b-v1.3)
- [EAGLE-1,3](https://github.com/SafeAILab/EAGLE?tab=readme-ov-file#eagle-weights)
- [Hydra](https://github.com/zankner/hydra?tab=readme-ov-file#model-weights)
- [Medusa-1](https://github.com/FasterDecoding/Medusa?tab=readme-ov-file#medusa-1)
- [Speculative Sampling](https://github.com/NJUNLP/MCSD?tab=readme-ov-file#model-release)
- [SPACE](https://huggingface.co/AntMan/vicuna-v1.3-7b-space)
## Additonal Setup
#### REST (Optional)
##### Build DraftRetriever from source
```
cd model/rest/DraftRetriever
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
maturin build --release --strip -i python3.12 # will produce a .whl file
pip3 install ./target/wheels/draftretriever-0.1.0-cp312-cp312-linux_x86_64.whl
```
##### Create a datastore
```
cd model/rest/datastore
./datastore.sh # modify your own path
```
## Inference
Select specific command line in `eval.sh`, the results will be stored in `data/spec_bench/model_answer/`.
```
./eval.sh
```
> We also provide an automatic evaluation script in `./scripts` for your reference.
## Speedup Report
Obtain the corresponding speedup compared to vanilla autoregressive decoding.
```
python evaluation/speed.py --file-path /your_own_path/eagle.jsonl --base-path /your_own_path/vicuna.jsonl
```
## Result Comparison
Examine whether the generated results are equal to autoregressive decoding or not.
```
python evaluation/equal.py --file-path /your_own_path/model_answer/ --jsonfile1 vicuna.jsonl --jsonfile2 eagle.jsonl
```
## Contributing
We warmly welcome contributions and discussions related to Spec-Bench! If you have any suggestions for improvements or ideas you'd like to discuss, please don't hesitate to open an issue. This will allow us to collaborate and discuss your ideas in detail.
***More models are welcome!*** - If you're aware of any open-source Speculative Decoding methods not currently included in Spec-Bench, we encourage you to contribute by submitting a pull request. This helps ensure Spec-Bench remains a comprehensive and fair benchmarking platform for comparing existing methods. Please ensure that your changes are well-tested before submission.
## Acknowledgments
This codebase is built from [Medusa](https://github.com/FasterDecoding/Medusa) and [EAGLE](https://github.com/SafeAILab/EAGLE). We integrated code implementations of multiple open-source Speculative Decoding methods to facilitate unified evaluation.
