Why a ranking does not choose for you
New AI models appear every few weeks, and each one leads some ranking. Public benchmarks are useful within their limits: Chatbot Arena measures which answers users prefer in anonymous comparisons, and HELM evaluates language models with several metrics across many scenarios. Neither measures how a model handles your documents, your language variety, your approval rules and your tools. Use rankings to pick two or three candidates, not to decide.
