Building a support chatbot
The failure mode for support AI isn't getting the answer wrong — it's confidently making something up and a customer acting on it. Claude's training makes it more likely to say it doesn't know or route to a human than to fabricate a policy or refund amount. For anything customer-facing, that predictability matters more than the last few benchmark percentage points. A wrong answer in a support context creates more work than no answer at all.
Cost at scale
The numbers matter more than people expect. At GPT-4o mini pricing ($0.15/1M input tokens), handling 100,000 typical support messages costs roughly $1.50 in AI costs. At full GPT-4o pricing, the same volume costs $25. At millions of messages, the difference is tens of thousands of dollars a month. Size your model to the task — most support queries don't need the most capable model, just one that's fast, consistent, and cheap.
