AIPerf supports benchmarking using the LLaVA-OneVision dataset, which contains a large multimodal collection of instruction-tuning examples covering charts, diagrams, scientific figures, natural photos, and more.
This guide uses the sharegpt4o subset — GPT-4o annotated ShareGPT conversations with natural
scene images.
Start a vLLM Server
Launch a vLLM server with a vision language model:
python -m vllm.entrypoints.openai.api_server \--model Qwen/Qwen2-VL-2B-Instruct \--host 127.0.0.1 \--port 8000
Verify the server is ready:
curl -s 127.0.0.1:8000/v1/chat/completions \-H "Content-Type: application/json" \-d '{"model":"Qwen/Qwen2-VL-2B-Instruct","messages":[{"role":"user","content":"test"}],"max_tokens":1}'
Profile with LLaVA-OneVision Dataset
AIPerf loads the sharegpt4o subset from HuggingFace, extracts the first user message and image
from each row, and sends each as a single-turn vision request.
aiperf profile \--model Qwen/Qwen2-VL-2B-Instruct \--endpoint-type chat \--streaming \--url 127.0.0.1:8000 \--public-dataset llava_onevision \--request-count 10 \--concurrency 4

LLaVA-OneVision’s GPT-4o annotated responses are detailed and verbose, producing longer output sequences than typical VQA datasets. Use
--prompt-output-tokens-meanto cap output length if needed.
