🛠 LLM Routers are Becoming a Distinct Service Category
The routing market is emerging as a standalone segment that allows for the optimization of costs and response quality. Instead of using a single expensive model, systems such as OpenRouter, LiteLLM, or Not Diamond dynamically distribute tasks: simple queries are sent to cheap models, while complex ones are sent to frontier models. For example, the AI editor Cursor reported a 30–50% reduction in costs by implementing an internal task complexity classifier.
🌍 Routing is becoming a critical management layer between the application and model providers, controlling costs, latency, and traffic distribution. This creates a conflict of interest between model developers and application developers.
👤 AI usage is becoming more efficient and affordable due to "smart" background switching between models, allowing complex features to be integrated into applications without a massive increase in token costs.
