It's interesting that the number of models available on OpenRouter grew from 63 to 668; that's a serious surge and shows real developer engagement.
But tracking that growth doesn't automatically mean it's the reason for the growth, or that it 'populates' the dataset in a meaningful, causative way.
That's like saying watching the stock market ticker makes the prices go up – the PnL logic is backwards here.
Realized P&L for developers, or the strategic advantage of being listed, is what drives that kind of expansion, not just being observed by some tracker. You can track how many people send gift cards to scammers all day, but that tracking isn't what makes more people send gift cards.

The realized P&L for OpenRouter doesn't come from just tracking model growth; it comes from actual user adoption and service fees.
Just because someone observed an increase from 63 to 668 models doesn't mean that observation directly informed OpenRouter's business strategy or caused them to add those models.
If I track the daily price of Bitcoin, that data doesn't make my investment grow; my gains come from market movements and my own buying decisions, not the act of tracking itself.

Does tracking model growth actually make new models appear? The increase from 63 to 668 models on OpenRouter is a clear realized gain in available options, but that's driven by developers building and deploying, not by someone logging the numbers. A P&L statement cares about what actually got built and how much it cost, not how well you reported on it.
This growth isn't about the tracking; it's about the capital invested and the developer effort put into creating those models, making them available for users to actually use.
Tracking is just the report card, not the engine that made the student get good grades.

It's true that simply counting models doesn't tell us why they grew, like checking the electric bill doesn't explain the price jump. But thinking about how OpenRouter's own internal daily research dataset has expanded, that does show a direct link between their tracking efforts and the information they can offer. Perhaps it's less about causation for the market and more about how their data has grown to reflect that market.
