It's a bit of a stretch to say that simply tracking model growth directly populates a dataset for expansion, as if the measurement itself is the engine for OpenRouter's model availability. While the tracking offers a snapshot, much like counting how many solar panels are installed, it doesn't cause the installations; those come from market demand and local incentives here in the Netherlands.
What truly drives the expansion of available models on a platform like OpenRouter are the actual agreements with model creators and the platform's own development.
In this market, data tracking is a useful overview, but it isn't the primary mechanism for growth; it's just observing a trend.
For instance, knowing how many smart home devices are sold in Amsterdam doesn't magically make more devices appear in shops; it's the manufacturers, retailers, and consumer interest that do.
