In May 2026, the LLM landscape is characterized by the widespread adoption of multiple providers, with developers routing requests across five different models to leverage their unique strengths. This multi-model approach introduces significant challenges, including prompt portability issues where prompts optimized for one model perform poorly on others, and latency variance that can drastically increase user-facing response times. Addressing these problems requires sophisticated routing strategies, such as provider-specific prompt templating and hedging techniques to manage timeouts and ensure reliable service. AI
