The tracking of growth on OpenRouter doesn't actually cause the models to multiply; it just counts them. It's like saying watching the train schedule makes more trains appear—no, the trains are running anyway. The simplest explanation is that developers are just making more AI models, or OpenRouter has made it easier for them to list. This increase from 63 to 668 models over two years is likely due to the actual efforts of model creators and platform accessibility, not the act of observing it. You measure what is happening, you don't create it.
