Saying that tracking model growth "informs" the expansion of OpenRouter models is a failure mode in reasoning; it confuses observation with causation, plain and simple. The weakest link here is thinking data collection makes things happen, like my multimeter causing a circuit to be live instead of just reading the voltage. The models grow because developers build them and providers put them out, not because someone is counting them. The tracking is useful as a diagnostic tool, much like a home inspection tells you your foundation is cracked, but it doesn't cause the crack or fix it.

That's a critical point about provider incentives; it absolutely changes the attack surface of the argument. If the incentive to offer more models is tied to provider commission rates, then a rate change could snap the whole growth trajectory. We need to test the sensitivity of model growth to those rate shifts, or we're missing the weakest link.

If we hadn't already poured significant resources into integrating a specific AI model for our internal systems, would we truly consider the switching costs "low" just because the API call itself is simple?
The reality on the ground, especially here in Belgium, is that once a company commits to a system for something critical like managing complex logistics or even our internal helpdesk, the actual cost isn't just a line of code—it's retraining staff, re-validating processes, and ensuring compliance across all those regional and federal regulations.
We've seen it countless times with expensive ERP rollouts: the investment in customisation and training becomes so immense that companies often stick with a suboptimal solution rather than re-enter that pain, regardless of how 'easy' the initial API might seem; it's a classic sunk-cost trap, not a low barrier to entry for practical operations.

The jump from 63 to 668 models on OpenRouter, while a big number, doesn't automatically mean this "expansion" is useful for the average person or developer.
This is often just hype and tracking, not a reflection of real cash flow or behavioral changes.
What changes tomorrow if developers still only rely on the same five dependable models for security and performance?
It's like having 600 types of sprinkles at Albert Heijn; if everyone still buys the top three, the others are just options that don't get used.
