AI Model Selection Economics
AI model selection economics is the pattern where users choose more capable, slower, or more expensive model classes for higher-value tasks and cheaper/faster models for simpler work.
Key points
- Anthropic uses Opus selection as a revealed-preference signal for when users believe higher intelligence is worth higher cost or scarce usage limits [src-071].
- Among paid Claude.ai users, Computer and Mathematical tasks use Opus more often than average, while Educational tasks use Opus less often [src-071].
- At the occupation level, Software Developer tasks use Opus more often than Tutor tasks, suggesting users calibrate model choice to task value and difficulty [src-071].
- For each additional $10 in estimated hourly task value, Opus share rises by about 1.5 percentage points on Claude.ai and 2.8 percentage points in first-party API traffic [src-071].
- API users appear more responsive to task value, likely because programmatic workflows make model routing, cost, and performance tradeoffs more explicit [src-071].
- For an AI operating system, model selection should become a routing habit: reserve strongest models for high-value, ambiguous, or failure-costly work and use lighter models for routine execution [src-071].
