Unannounced model swaps in routing layers hide costs, quality drops, and compliance risks.
Intelligent request routing through a single gateway cuts LLM costs by 30 to 50 percent.
A gateway layer can unify caching across providers with different implementations.

Latency splits into three metrics, and routing decisions fail when teams measure the wrong one.
A central gateway eliminates duplicated retry logic across services.
Balances cost, speed, and quality as simultaneous signals rather than competing priorities.
