Problem
Paying Sonnet rates for Haiku tickets.
50K tickets per month, 80% routine (order status, password reset, shipping), 20% complex (billing disputes, damage claims). Everything went to Sonnet at $28K/month to guarantee quality on the 20% edge cases.
Solution
Let the router learn the map.
model: "auto" + Guardian Intelligence + Thompson sampling. The router observed satisfaction scores and discovered 47 query patterns in 60 days. No manual routing rules.
Outcome-driven routing
Router optimizes on satisfaction + speed, not cost alone. Sonnet's depth focuses on nuanced disputes — billing, custom orders, damage claims.
Guardian Intelligence
Per-pattern satisfaction tracking. No manual rules means the policy self-adjusts as query volume shifts seasonally.
“First-contact resolution jumped because Sonnet's depth now focused exclusively on nuanced disputes.”
