Production's Hidden Bottleneck: Why LLM Routing Matters More Than Model Choice

As AI applications scale to production, the bottleneck shifts from code generation to infrastructure reliability. The real challenge lies in routing requests across multiple LLM providers to handle outages, rate limits, cost variations, and latency differences. Developers relying on single-provider setups need production-grade routing strategies that many overlook—a gap that sophisticated failover architectures must address.
