Which platform should you choose?
Choose representative tasks and failure cases, then compare tracing, evaluator calibration, dataset management, retention, and full usage costs. Human review helps identify where automated evaluation misses important errors. Validate claims with the vendor and test the important workflow with your team. Differences shown here are evaluation prompts, not hands-on performance findings.
