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
