Smart Model Switching
Three-tier Claude routing: Haiku → Sonnet → Opus
Start with the cheapest model. Escalate only when needed. Save 50-90% on API costs.
The Golden Rule
If a human would need more than 30 seconds of focused thinking, escalate from Haiku to Sonnet. If the task involves architecture, complex tradeoffs, or deep reasoning, escalate to Opus.
Cost Reality
| Model | Input | Output | Relative Cost |
|---|---|---|---|
| Haiku | $0.25/M | $1.25/M | 1x (baseline) |
| Sonnet | $3.00/M | $15.00/M | 12x |
| Opus | $15.00/M | $75.00/M | 60x |
