Before trying Qwen or another new model, compare accuracy, output format, and cost on your own task set to decide whether to migrate.Developers load real tasks and expected answers into a test suite, then run different models against the same inputs to compare factual errors, formatting deviations, latency, and cost. Model versions and prompts are retained so earlier results can be rerun.
