That’s a great real-world example. Switching providers mid-project is exactly where the tight coupling starts to hurt.

For latency, the cleanest approach is usually latency-aware routing at the gateway layer. The gateway can track response times per provider/model and route traffic to the fastest healthy option, with fallback rules if performance degrades. Some teams also keep different routing profiles per workload (e.g., low-latency vs high-reasoning tasks).
