When do you need multi-model routing?¶

Short answer: Stay single-model for one stable workload; add multi-model routing when you have data tiers, cost spikes, or capability gaps — default private AW36, overflow commercial APIs via policy, not manual switching.

Four triggers (two is enough)¶

1. Data tiers — sensitive text stays private; public search can use SaaS
2. Cost spikes — daily volume swings >3×
3. Capability mix — extract / summarize / code / multimodal need different winners
4. SLA layers — counter latency vs batch jobs

Quotable KPIs¶

• ~41% monthly inference cost drop after routing
• Sensitive hospital path 100% on AW36, zero egress
• Peak overflow to commercial APIs with controlled P95
