In a hybrid architecture, new frontier models don't immediately become part of the critical routing path. They enter through an evaluation layer where they're benchmarked against existing systems across reasoning quality, latency, context retention, consistency, and cost efficiency.
So when a stronger model emerges, the question isn't "How do we rebuild the stack around it?" but rather "Which workloads does it outperform on?"
If it demonstrates superior performance in a given category, the routing engine can gradually allocate traffic to it while continuously monitoring outcomes against existing models.
