How it works

Get evidence for your next rollout.

Send your model, GPU and vLLM versions.

You confirm the scope. We test both versions under the same agreed conditions.

See which checks passed, which need investigation and what wasn't tested.

DSpark and FA4: known correctness defects and fixed controls.

Qwen: requests completed with the required output length.

These are public calibration workloads, not customer checks. Qwen answer correctness was not assessed. Speed is not calibrated.

Every finding names the tested versions, workload and configuration. PASS applies only to the listed checks. Untested behavior is marked clearly.

Email your model, GPU and the versions to compare. We confirm scope and availability before testing.

First supported check: Free.

Subject to available free places. No card required.

Do not send secrets or production data.
