-## Description
-
-This file contains the downloading link for benchmarking results.
-
-- [benchmarking pipeline](artifact://nightly-pipeline.yaml)
-- [benchmarking results](artifact://results.zip)
-- [benchmarking code](artifact://nightly-benchmarks.zip)
-
-Please download the visualization scripts in the post
-
-## Results reproduction
-
-- Find the docker we use in `benchmarking pipeline`
-- Deploy the docker, and inside the docker:
-    - Download `nightly-benchmarks.zip`.
-    - In the same folder, run the following code:
-
-    ```bash
-    export HF_TOKEN=<your HF token>
-    apt update
-    apt install -y git
-    unzip nightly-benchmarks.zip
-    VLLM_SOURCE_CODE_LOC=./ bash .buildkite/nightly-benchmarks/scripts/run-nightly-benchmarks.sh
-    ```
-
-And the results will be inside `./benchmarks/results`.

-# Nightly benchmark
-
-This benchmark aims to:
-
-- Provide performance clarity: Provide clarity on which one (vllm, tensorrt-llm, lmdeploy and SGLang) leads in performance in what workload.
-- Be reproducible: one can run the exact same set of benchmarking commands inside the exact same docker by following reproducing instructions.
-
-Latest results: [results link](https://blog.vllm.ai/2024/09/05/perf-update.html), scroll to the end.
-
-Latest reproduction guide: [github issue link](https://github.com/vllm-project/vllm/issues/8176)
-
-## Setup
-
-- Docker images:
-    - vLLM: `vllm/vllm-openai:v0.6.2`
-    - SGLang: `lmsysorg/sglang:v0.3.2-cu121`
-    - LMDeploy: `openmmlab/lmdeploy:v0.6.1-cu12`
-    - TensorRT-LLM: `nvcr.io/nvidia/tritonserver:24.07-trtllm-python-py3`
-        - *NOTE: we use r24.07 as the current implementation only works for this version. We are going to bump this up.*
-    - Check [nightly-pipeline.yaml](nightly-pipeline.yaml) for the concrete docker images, specs and commands we use for the benchmark.
-- Hardware
-    - 8x Nvidia A100 GPUs
-- Workload:
-    - Dataset
-        - ShareGPT dataset
-        - Prefill-heavy dataset (in average 462 input tokens, 16 tokens as output)
-        - Decode-heavy dataset (in average 462 input tokens, 256 output tokens)
-        - Check [nightly-tests.json](tests/nightly-tests.json) for the concrete configuration of datasets we use.
-    - Models: llama-3 8B, llama-3 70B.
-        - We do not use llama 3.1 as it is incompatible with trt-llm r24.07. ([issue](https://github.com/NVIDIA/TensorRT-LLM/issues/2105)).
-    - Average QPS (query per second): 2, 4, 8, 16, 32 and inf.
-        - Queries are randomly sampled, and arrival patterns are determined via Poisson process, but all 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).
-
-## Known issues
-
-- TRT-LLM crashes with Llama 3.1 8B [issue](https://github.com/NVIDIA/TensorRT-LLM/issues/2105).
-- TGI does not support `ignore-eos` flag.

 ## Introduction
 
-This directory contains two sets of benchmark for vllm.
-
-- Performance benchmark: benchmark vllm's performance under various workload, for **developers** to gain clarity on whether their PR improves/degrades vllm's performance
-- Nightly benchmark: compare vllm's performance against alternatives (tgi, trt-llm and lmdeploy), for **the public** to know when to choose vllm.
-
-See [vLLM performance dashboard](https://hud.pytorch.org/benchmark/llms?repoName=vllm-project%2Fvllm) for the latest performance benchmark results and [vLLM GitHub README](https://github.com/vllm-project/vllm/blob/main/README.md) for latest nightly benchmark results.

-## Nightly test details
-
-See [nightly-descriptions.md](nightly-descriptions.md) for the detailed description on test workload, models and docker containers of benchmarking other llm engines.
-
-### Workflow
-
-- The [nightly-pipeline.yaml](nightly-pipeline.yaml) specifies the docker containers for different LLM serving engines.
-- Inside each container, we run [scripts/run-nightly-benchmarks.sh](scripts/run-nightly-benchmarks.sh), which will probe the serving engine of the current container.
-- The `scripts/run-nightly-benchmarks.sh` will parse the workload described in [nightly-tests.json](tests/nightly-tests.json) and launch the right benchmark for the specified serving engine via `scripts/launch-server.sh`.
-- At last, we run [scripts/summary-nightly-results.py](scripts/summary-nightly-results.py) to collect and plot the final benchmarking results, and update the results to buildkite.
-
-### Nightly tests
-
-In [nightly-tests.json](tests/nightly-tests.json), we include the command line arguments for benchmarking commands, together with the benchmarking test cases. The format is highly similar to performance benchmark.
-
-### Docker containers
-
-The docker containers for benchmarking are specified in `nightly-pipeline.yaml`.
-
-WARNING: the docker versions are HARD-CODED and SHOULD BE ALIGNED WITH `nightly-descriptions.md`. The docker versions need to be hard-coded as there are several version-specific bug fixes inside `scripts/run-nightly-benchmarks.sh` and `scripts/launch-server.sh`.
-
-WARNING: populating `trt-llm` to latest version is not easy, as it requires updating several protobuf files in [tensorrt-demo](https://github.com/neuralmagic/tensorrt-demo.git).

+This benchmark runs the same workload twice:
+1. With VLLM_BATCH_INVARIANT=0 (baseline)
+2. With VLLM_BATCH_INVARIANT=1 (batch invariant mode)
+
+And reports the timing and throughput metrics for comparison.
+
+Environment variables:
+    VLLM_BENCH_MODEL: Model to benchmark (default: "Qwen/Qwen3-1.7B")
+    VLLM_BENCH_TP_SIZE: Tensor parallel size (default: 1, use 8 for deepseek)
+    VLLM_BENCH_BATCH_SIZE: Max batch size (default: 128)
+    VLLM_BENCH_NUM_TRIALS: Number of trials to run (default: 5)
+    VLLM_BENCH_MIN_PROMPT: Min prompt length in words (default: 1024)
+    VLLM_BENCH_MAX_PROMPT: Max prompt length in words (default: 2048)
+    VLLM_BENCH_MAX_TOKENS: Max tokens to generate (default: 128)
+    VLLM_BENCH_TEMPERATURE: Temperature for sampling (default: 0.0)
