# Profile with InstructCoder Dataset

AIPerf supports benchmarking using the InstructCoder dataset (`likaixin/InstructCoder`), which
contains code editing and generation instructions. This dataset is useful for measuring model
throughput and latency under code generation workloads.

This guide covers profiling OpenAI-compatible chat completions endpoints using the InstructCoder
public dataset.

---

## Start a vLLM Server

Launch a vLLM server with a chat model:

```bash
docker pull vllm/vllm-openai:latest
docker run --gpus all -p 8000:8000 vllm/vllm-openai:latest \
  --model Qwen/Qwen3-0.6B
```

Verify the server is ready:
```bash
curl -s localhost:8000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model":"Qwen/Qwen3-0.6B","messages":[{"role":"user","content":"test"}],"max_tokens":1}'
```

## Profile with InstructCoder Dataset

AIPerf loads the InstructCoder dataset from HuggingFace and uses each instruction as a
single-turn prompt.

<!-- aiperf-run-vllm-default-openai-endpoint-server -->
```bash
aiperf profile \
    --model Qwen/Qwen3-0.6B \
    --endpoint-type chat \
    --streaming \
    --url localhost:8000 \
    --public-dataset instruct_coder \
    --output-tokens-mean 1024 \
    --request-count 10 \
    --concurrency 4
```
<!-- /aiperf-run-vllm-default-openai-endpoint-server -->

**Sample Output (Successful Run):**

This sample was captured without `--output-tokens-mean`, so its output sequence lengths can exceed the 1024-token mean set above.

```
