The premise
AI model selection trades capability against cost and latency — frontier models for hard reasoning, mid-tier for routine quality work, small models for high-volume narrow tasks.
What AI does well here
- Frontier: complex multi-step reasoning, code, novel synthesis
- Mid-tier: routine analysis, summarization, structured extraction
- Small: classification, routing, simple transforms
- All tiers: predictable behavior on clearly-scoped tasks
What AI cannot do
- Recommend a tier without knowing your accuracy and cost requirements
- Substitute small models for frontier on genuinely complex reasoning
