OpenRouter shows how teams can route for lower-cost LLM inference

OpenRouter has published a tutorial on using its platform to find lower-cost LLM inference.

The useful signal is that inference cost is becoming dynamic. Teams can route across providers and models depending on latency, price, reliability, and task requirements instead of committing every request to one endpoint.

For production AI apps, that makes the gateway layer strategically important. It is where cost controls, fallback behavior, and model selection can be managed without rewriting the product.
