As of July 2026, mid-tier AI models cost roughly $2 to $3 per million input tokens and $10 to $15 per million output tokens, so a normal question and answer costs a fraction of a cent. The running bill only becomes significant at high volume or with very large inputs on every call.
The part that determines success isn't the model fee. It's the engineering around it: giving the model the right data, testing for accuracy, and building guardrails so it fails safely. That's where the real budget goes, and where cheap builds cut corners.
