# ArcticSpeculator

Build a fastest OSS vllm-based speculative decoding system for your own model, using [ArcticTraining](https://github.com/snowflakedb/ArcticTraining) and [ArcticInference](https://github.com/snowflakedb/ArcticInference)!

We compare the throughput (tokens/s) of existing vllm-based speculative decoding systems for Llama3.1-70B-Instruct on 8xH100 as below:

| method                                 | ShareGPT      | HumanEval |
|--------------------------------------|----------------|--------------|
| VLLM V1 Baseline      | 84.1 | 84.1    |
| VLLM V1 Eagle | 102.2   | 112.0    |
| VLLM V1 Eagle3  | 77.7   | 85.3 |
| VLLM V0 MLP-Speculator (IBM) | 77.9   | 66.7        |
| ArcticSpeculator                          | **172.4**   | **203.7**    |

We also release ArcticSpeculator checkpoints we trained with [ArcticTraining](https://github.com/snowflakedb/ArcticTraining) to run with [ArcticInference](https://github.com/snowflakedb/ArcticInference):
