Mixture-of-Models

The pattern

Mixture-of-Models composes eligible specialists when a governed multi-stage plan can improve an outcome. Each stage must remain policy-eligible, attributable, bounded, and evaluable.

• Decompose only when added complexity has a measurable purpose.
• Preserve stage-level model and provider evidence.
• Bound total latency, cost, attempts, and failure behavior.
• Evaluate the composed result, not only individual stages.
