- Performance clarity: Provide clarity on which one (vllm, tensorrt-llm, lmdeploy and tgi) leads in performance in what workload.
- Reproducible: one can run the exact same set of benchmarking commands inside the exact same docker by following reproducing instructions in [reproduce.md]().
## Docker images
We benchmark vllm, tensorrt-llm, lmdeploy and tgi using the following docker images:
<!-- Please check <a href="artifact://workspace/build/buildkite/vllm/performance-benchmark/.buildkite/nightly-benchmarks/nightly-pipeline.yaml">nightly-pipeline.yaml</a> artifact for more details on how we deploy the docker images. -->
## Hardware
One AWS node with 8x NVIDIA A100 GPUs.
## Workload description
We benchmark vllm, tensorrt-llm, lmdeploy and tgi using the following workload:
- Input length: randomly sample 500 prompts from ShareGPT dataset (with fixed random seed).
- Output length: the corresponding output length of these 500 prompts.
- Models: llama-3 8B, llama-3 70B, mixtral 8x7B.
- Average QPS (query per second): 4 for the small model (llama-3 8B) and 2 for other two models. For each QPS, the arrival time of each query is determined using a random Poisson process (with fixed random seed).
- Evaluation metrics: Throughput (higher the better), TTFT (time to the first token, lower the better), ITL (inter-token latency, lower the better).

## Plots
In the following plots, the dot shows the mean and the error bar shows the standard error of the mean. Value 0 means that the corresponding benchmark crashed.
- Input length: randomly sample 200 prompts from ShareGPT dataset (with fixed random seed).
- Output length: the corresponding output length of these 200 prompts.
- Batch size: dynamically determined by vllm to achieve maximum throughput.
- Models: llama-3 8B, llama-3 70B, mixtral 8x7B.
- Evaluation metrics: throughput.

## Serving tests
This test suite aims to test vllm's real serving metrics.
- Input length: randomly sample 200 prompts from ShareGPT dataset (with fixed random seed).
- Output length: the corresponding output length of these 200 prompts.
- Batch size: dynamically determined by vllm and the arrival pattern of the requests.
-**Average QPS (query per second)**: 1, 4, 16 and inf. QPS = inf means all requests come at once. For other QPS values, the arrival time of each query is determined using a random Poisson process (with fixed random seed).
- Models: llama-3 8B, llama-3 70B, mixtral 8x7B.
- Evaluation metrics: throughput, TTFT (time to the first token, with mean, median and p99), ITL (inter-token latency, with mean, median and p99).
